Group II selective metabotropic glutamate receptor agonists and local cerebral glucose use in the rat. (1/66)

The novel mGluR agonist LY354740 and a related analogue LY379268 are selective for mGluR2/3 receptors and are centrally active after systemic administration. In this study, rates of local cerebral glucose use were measured using the [14C]2-deoxyglucose autoradiographic technique to examine the functional consequences of their systemic administration in the conscious rat. Both LY354740 (0.3, 3.0, 30 mg/kg) and LY379268 (0.1, 1.0, 10 mg/kg) produced dose-dependent changes in glucose use. After LY354740 (3.0mg/kg), 4 of the 42 regions measured showed statistically significant changes from vehicle-treated controls: red nuclei (-16%), mammillary body (-25%), anterior thalamus (-29%), and the superficial layer of the superior colliculus (+50%). An additional 15 regions displayed significant reductions in function-related glucose use (P < .05) in animals treated with LY354740 (30 mg/ kg). LY379268 (0.1, 1.0, 10 mg/kg) produced changes in glucose metabolism in 20% of the brain regions analyzed. Significant increases (P < .05) in glucose use were evident in the following: the superficial layer of the superior colliculus (+81%), locus coeruleus (+57%), genu of the corpus callosum (+31%), cochlear nucleus (+26%), inferior colliculus (+20%), and the molecular layer of the hippocampus (+14%). Three regions displayed significant decreases: mammillary body (-34%), anteroventral thalamic nucleus (-28%), and the lateral habenular nucleus (-24%). These results show the important functional involvement of the limbic system together with the participation of components of different sensory systems in response to the activation of mGluR2 and mGluR3 with LY354740 and LY379268.  (+info)

Primary somatosensory cortex activation is not altered in patients with ventroposterior thalamic lesions: a PET study. (2/66)

BACKGROUND AND PURPOSE: We know remarkably little about the mechanisms underlying cortical activation. Such mechanisms might be better understood by studying the effect of well-localized lesions on the cortical activations in simple paradigms. METHODS: We used H(2)(15)O and positron emission tomography to measure regional cerebral blood flow (rCBF) at rest and during hand vibration in 7 patients with unilateral thalamic lesion involving the ventroposterior (VP) somatosensory thalamic relay nuclei. We compared the results with those obtained in 6 patients with thalamic lesions sparing the VP nuclei and 6 healthy controls. RESULTS: The patients with VP lesions had a selective hypoperfusion at rest in the ipsilesional primary sensorimotor cortex (SM1). This hypoperfusion was significantly correlated with the degree of contralateral somatosensory deficit. This abnormality may reflect the deafferentation of SM1 from its somatosensory thalamic input. Despite this deafferentation, the ipsilesional SM1 was normally activated by the vibration of the hypoesthetic hand. CONCLUSIONS: The fact that a lesion of the somatosensory thalamic relay nuclei alters the rCBF at rest in SM1 but not its activation by hand vibration indicates that the mechanism of cortical activation is complex, even in the case of simple sensory stimulation. In addition, a dissociation may occur between obvious neurological deficits and apparently normal activation patterns, which suggests that activation studies should be interpreted cautiously in patients with focal brain lesions.  (+info)

Calcium-independent afterdepolarization regulated by serotonin in anterior thalamus. (3/66)

Previous studies have identified an afterdepolarization (ADP) in thalamocortical neurons that is mediated by an upregulation of the hyperpolarization-activated current I(h). This ADP has been suggested to play a key role in the generation of spindle oscillations. In the lateral geniculate nucleus, upregulation of I(h) has been shown to be signaled by a rise in intracellular calcium leading to the activation of adenylate cyclase and formation of cAMP. However, it is unclear how generalizable this mechanism is to other thalamic nuclei. We have used whole cell recording to examine the electrophysiological properties of neurons of the anterodorsal thalamic nucleus, a nucleus thought not to undergo spindle oscillations. We now report that cells in this nucleus also display an ADP mediated by I(h). Surprisingly, the ADP and the underlying upregulation of I(h) persisted even after buffering intracellular calcium and blocking calcium influx. These results indicate that, in neurons of the anterodorsal thalamic nucleus, an I(h)-mediated ADP can occur through a mechanism that does not involve a rise in intracellular calcium. We next examined the possibility that this calcium-independent ADP might be modulated by serotonin. Serotonin produced a robust enhancement in the amplitude of the ADP even after strong buffering of intracellular calcium and blockade of calcium channels. These results indicate that neurons of the anterodorsal thalamic nucleus display a calcium-independent, I(h)-mediated ADP and that this ADP is a target for regulation by serotonin. These findings identify a novel mechanism by which serotonin can regulate neuronal excitability.  (+info)

Modeling attractor deformation in the rodent head-direction system. (4/66)

We present a model of the head-direction circuit in the rat that improves on earlier models in several respects. First, it provides an account of some of the unique characteristics of head-direction (HD) cell firing in the lateral mammillary nucleus and the anterior thalamus. Second, the model functions without making physiologically unrealistic assumptions. In particular, it implements attractor dynamics in postsubiculum and lateral mammillary nucleus without directionally tuned inhibitory neurons, which have never been observed in vivo, and it integrates angular velocity without the use of multiplicative synapses. The model allows us to examine the relationships among three HD areas and various properties of their representations. A surprising result is that certain combinations of purported HD cell properties are mutually incompatible, suggesting that the lateral mammillary nucleus may not be the primary source of head direction input to anterior thalamic HD cells.  (+info)

Coinciding early activation of the human primary visual cortex and anteromedial cuneus. (5/66)

Proper understanding of processes underlying visual perception requires information on the activation order of distinct brain areas. We measured dynamics of cortical signals with magnetoencephalography while human subjects viewed stimuli at four visual quadrants. The signals were analyzed with minimum current estimates at the individual and group level. Activation emerged 55-70 ms after stimulus onset both in the primary posterior visual areas and in the anteromedial part of the cuneus. Other cortical areas were active after this initial dual activation. Comparison of data between species suggests that the anteromedial cuneus either comprises a homologue of the monkey area V6 or is an area unique to humans. Our results show that visual stimuli activate two cortical areas right from the beginning of the cortical response. The anteromedial cuneus has the temporal position needed to interact with the primary visual cortex V1 and thereby to modify information transferred via V1 to extrastriate cortices.  (+info)

Background, but not foreground, spatial cues are taken as references for head direction responses by rat anterodorsal thalamus neurons. (6/66)

Two populations of limbic neurons are likely neurophysiological substrates for cognitive operations required for spatial orientation and navigation: hippocampal pyramidal cells discharge selectively when the animal is in a certain place (the "firing field") in the environment, whereas head direction cells discharge when the animal orients its head in a specific, "preferred" direction. Cressant et al. (1997) showed that the firing fields of hippocampal place cells reorient relative to a group of three-dimensional objects only if these are at the periphery, but not the center of an enclosed platform. To test for corresponding responses in head direction cells, three objects were equally spaced along the periphery of a circular platform. Preferred directions were measured before and after the group of objects was rotated. (The rat was disoriented in total darkness between sessions). This was repeated in the presence or absence of a cylinder enclosing the platform. When the enclosure was present, the preferred directions of all 30 cells recorded shifted by the same angle as the objects. In the absence of the enclosure, the preferred directions did not follow the objects, remaining fixed relative to the room. These results provide a possible neurophysiological basis for observations from psychophysical experiments in humans that background, rather than foreground, cues are preferentially used for spatial orientation.  (+info)

Active locomotion increases peak firing rates of anterodorsal thalamic head direction cells. (7/66)

Head direction (HD) cells discharge selectively in macaques, rats, and mice when they orient their head in a specific ("preferred") direction. Preferred directions are influenced by visual cues as well as idiothetic self-motion cues derived from vestibular, proprioceptive, motor efferent copy, and command signals. To distinguish the relative importance of active locomotor signals, we compared HD cell response properties in 49 anterodorsal thalamic HD cells of six male Long-Evans rats during active displacements in a foraging task as well as during passive rotations. Since thalamic HD cells typically stop firing if the animals are tightly restrained, the rats were trained to remain immobile while drinking water distributed at intervals from a small reservoir at the center of a rotatable platform. The platform was rotated in a clockwise/counterclockwise oscillation to record directional responses in the stationary animals while the surrounding environmental cues remained stable. The peak rate of directional firing decreased by 27% on average during passive rotations (r(2) = 0.73, P < 0.001). Individual cells recorded in sequential sessions (n = 8) reliably showed comparable reductions in peak firing, but simultaneously recorded cells did not necessarily produce identical responses. All of the HD cells maintained the same preferred directions during passive rotations. These results are consistent with the hypothesis that the level of locomotor activity provides a state-dependent modulation of the response magnitude of AD HD cells. This could result from diffusely projecting neuromodulatory systems associated with motor state.  (+info)

The conjoint importance of the hippocampus and anterior thalamic nuclei for allocentric spatial learning: evidence from a disconnection study in the rat. (8/66)

A disconnection procedure was used to test whether the hippocampus and anterior thalamic nuclei form functional components of the same spatial memory system. Unilateral excitotoxic lesions were placed in the anterior thalamic (AT) nuclei and hippocampus (HPC) in either the same (AT-HPC Ipsi group) or contralateral (AT-HPC Contra group) hemispheres of rats. The behavioral effects of these combined lesions were compared in several spatial memory tasks sensitive to bilateral hippocampal lesions. In all of the tasks tested, T-maze alternation, radial arm maze, and Morris water maze, those animals with lesions placed in the contralateral hemispheres were more impaired than those animals with lesions in the same hemisphere. These results provide direct support for the notion that the performance of tasks that require spatial memory rely on the operation of the anterior thalamus and hippocampus within an integrated neural network.  (+info)

The anterior thalamic nuclei are important for spatial and episodic memory, however, surprisingly little is known about the status of these nuclei in neurological conditions that present with memory impairments, such as Down syndrome. We quantified neurons and glial cells in the anterior thalamic nuclei of four older patients with Down syndrome. There was a striking reduction in the volume of the anterior thalamic nuclei and this appeared to reflect the loss of approximately 70% of neurons. The number of glial cells was also reduced but to a lesser degree than neurons. The anterior thalamic nuclei appear to be particularly sensitive to effects of aging in Down syndrome and the pathology in this region likely contributes to the memory impairments observed. These findings reaffirm the importance of examining the status of the anterior thalamic nuclei in conditions where memory impairments have been principally assigned to pathology in the medial temporal lobe ...
The hippocampus projects to the anterior thalamic nuclei both directly and indirectly via the mammillary bodies, but little is known about the electrophysiological properties of these convergent pathways. Here we demonstrate, for the first time, the presence of long-term plasticity in anterior thalamic nuclei synapses in response to high- and low-frequency stimulation (LFS) in urethane-anesthetized rats. We compared the synaptic changes evoked via the direct vs. the indirect hippocampal pathways to the anterior thalamus, and found that long-term potentiation (LTP) of the thalamic field response is induced predominantly through the direct hippocampal projections. Furthermore, we have estimated that that long-term depression (LTD) can be induced only after stimulation of the indirect connections carried by the mammillothalamic tract. Interestingly, basal synaptic transmission mediated by the mammillothalamic tract undergoes use-dependent, BDNF-mediated potentiation, revealing a distinct form of ...
The anterior thalamic nuclei (ATN), a central component of Papez circuit, are generally assumed to be key constituents of the neural circuits responsible for certain categories of learning and memory. Supporting evidence for this contention is that damage to either of two brain regions, the medial temporal lobe and the medial diencephalon, is most consistently associated with anterograde amnesia. Within these respective regions, the hippocampal formation and the ATN (anteromedial, anteroventral, and anterodorsal) are the particular structures of interest. The extensive direct and indirect hippocampal-anterior thalamic interconnections and the presence of theta-modulated cells in both sites further support the hypothesis that these structures constitute a neuronal network crucial for memory and cognition. The major tool in understanding how the brain processes information is the analysis of neuronal output at each hierarchical level along the pathway of signal propagation coupled with ...
Take-home message - two key findings: (1) there are head-direction cells in the anteroventral thalamus (head direction cells fire when the head is pointed in a particular orientation); (2) a large fraction of these cells are theta-modulated (a strong 7-12 Hz oscillation in the EEG, studied most frequently in the hippocampal formation). These data are interesting because they suggests that the anterior thalamus…

The brain regions that may be functionally involved in the control of anxiety and the development of seizures were examined using quantitative 1-14C-deoxyglucose autoradiography. For this purpose, beta- carbolines FG 7142 and DMCM were employed. They exert their effects via the benzodiazepine receptor, and whereas both possess anxiogenic properties, FG 7142 is a proconvulsant and DMCM a potent convulsant. The pattern of increases of local cerebral glucose utilization (LCGU) induced by FG 7142 was mainly restricted to limbic structures, such as the lateral septal nucleus, the anterior thalamic nuclei, and the mamillary nuclei. However, structures involved in motor regulation were also affected. A pronounced increase in LCGU was observed in the posterior part of the substantia nigra, pars reticulata. Further, the LCGU of the globus pallidus, the ventral thalamic nucleus, and the cerebellum was increased. DMCM likewise increased LCGU of the mamillary body and the lateral septal nucleus. In contrast ...
The study of the limbic system explains how emotions are generated. Four interconnected modules: the hypothalamus, the anterior thalamic nucleus, the cingulate gyrus and the hippocampus
Some neurons encode information about the orientation or position of an animal, and can maintain their response properties in the absence of visual input. Examples include head direction cells in rats and primates, place cells in rats and spatial view cells in primates. Continuous attractor neural networks model these continuous physical spaces by using recurrent collateral connections between the neurons which reflect the distance between the neurons in the state space (e.g. head direction space) of the animal. These networks maintain a localized packet of neuronal activity representing the current state of the animal. We show how the synaptic connections in a one-dimensional continuous attractor network (of for example head direction cells) could be self-organized by associative learning. We also show how the activity packet could be moved from one location to another by idiothetic (self-motion) inputs, for example vestibular or proprioceptive, and how the synaptic connections could self-organize to
The cytokine interleukin-1 (IL-1) has a number of biologic activities, including pronounced effects on the nervous and neuroendocrine systems. In this study, in situ histochemical techniques were used to investigate the distribution of cells expressing type I IL-1 receptor mRNA in the CNS, pituitary, and adrenal gland of the mouse. Hybridization of 35S-labeled antisense cRNA probes derived from a murine T-cell IL-1 receptor cDNA revealed a distinct regional distribution of the type I IL-1 receptor, both in brain and in the pituitary gland. In the brain, an intense signal was observed over the granule cell layer of the dentate gyrus, over the entire midline raphe system, over the choroid plexus, and over endothelial cells of postcapillary venules throughout the neuraxis. A weak to moderate signal was observed over the pyramidal cell layer of the hilus and CA3 region of the hippocampus, over the anterodorsal thalamic nucleus, over Purkinje cells of the cerebellar cortex, and in scattered clusters ...
Thalamic contributions to memory were assessed in monkeys with lesions placed in the medial portions of either the anterior or posterior thalamus (AMT and PMT respectively). Nine cynomolgus monkeys (Macaca fascicularis) were trained on a recognition task which required the animal to select a novel object in preference to a sample object which had been presented to the monkey 10s earlier. Three monkeys then received surgical lesions centred in the anterior nuclei (AMT) and three received lesions centred in nucleus medialis dorsalis (PMT). Although the experimental monkeys rapidly relearned this task of object recognition, both the AMT and PMT groups performed significantly worse than the unoperated control monkeys when the task was made harder by requiring the animals to distinguish the sample objects after increasing delays (30s, 60s, 120s) or after additional intervening objects (3, 5, and then 10). Furthermore, all three PMT animals and two of the AMT group were moderately impaired on a test ...

The thalamus has now been almost completely removed, the anterior and medial portion being all that remains. The subthalamic nucleus is left in place. Fibers of the ansa lenticularis (5) lie above this nucleus and pass laterally toward the ventral lateral nucleus (now removed) and ventral anterior nucleus (removed). The mass of fibers which forms the posterior stalk of the thalamus is visible in the lateral and posterior wall of the thalamic dissection. The fasciculus retroflexus is exposed farther ventrally toward the interpeduncular fossa ...
Our previous study found volume reduction of the amygdala when we estimated regional GM volume using optimized VBM for the PD patients.37 The present study showed volume reduction of amygdala in PD patients, confirmed on both manual tracing and optimized VBM with small-volume correction. Furthermore, smaller amygdala was associated with anxiety, suggesting that the amygdala, especially the corticomedial nuclear group, is a crucial area of the neurobiological pathway underlying PD.. The amygdala is a heterogeneous collection of nuclear groups located in the temporal lobe.38 A variety of different functions has been attributed to the amygdaloid complex, including memory, attention, interpretation of emotional significance of sensory stimuli, perception of body movements and generation of emotional aspects of dreams.39-41 The amygdala consists of anterior nucleus (AN), LA, BA, CE, ME, CO and ABA. Notably, LA, BA and CE are candidate nuclei related to PD pathophysiology.42,43 The LA and BA receive ...

The Seizure and Cognitive Outcome of Anterior Thalamic Nucleus Deep Brain Stimulation for Patients with Intractable Epilepsy, Yuguang Guan, Sichang Chen, Yao Zhang, Changqing Liu,
The treatment of patients with refractory epilepsy has always been challenging. Despite the availability of multiple antiepileptic medications and surgical procedures with which to resect seizure foci, there is a subset of epilepsy patients for whom little can be done. Currently available treatment options for these unfortunate patients include vagus nerve stimulation, the ketogenic diet, and electric stimulation, both direct and indirect, of brain nuclei thought to be involved in epileptogenesis. Studies of electrical stimulation of the brain in epilepsy treatment date back to the early 20th century, beginning with research on cerebellar stimulation. The number of potential targets has increased over the years to include the hippocampus, subthalamic nucleus, caudate nucleus, centromedian nucleus, and anterior nucleus of the thalamus (ANT). Recently the results of a large randomized controlled trial, the electrical Stimulation of the Anterior Nucleus of Thalamus for Epilepsy (SANTE) trial, were ...
Discrete populations of brain cells signal heading direction, rather like a compass. These head direction cells are largely confined to a closely-connected network of sites. We describe, for the first time, a population of head direction cells in nucleus reuniens of the thalamus in the freely-moving rat. This novel subcortical head direction signal potentially modulates the hippocampal CA fields directly and, thus, informs spatial processing and memory. ...
TY - JOUR. T1 - MR imaging of compact white matter pathways. AU - Curnes, J. T.. AU - Burger, P. C.. AU - Djang, W. T.. AU - Boyko, Orest. PY - 1988. Y1 - 1988. N2 - A prominent decreased signal intensity can be seen in many of the heavily myelinated, compact fiber pathways of the brain on T2-weighted spin-echo MR images (TR = 2500 msec, TE = 80 msec). These areas include the anterior commissure, internal capsule, optic tract and radiations, fornix, mammillothalamic tract, superior frontooccipital fasciculus, cingulum, corpus callosum, uncinate fasciculus, and superior longitudinal fasciculus. All these pathways could be identified in normal subjects 3 years old and older when 1.5-T axial and coronal images of 50 adults and 17 children were reviewed. Correlation of the in vivo and postmortem MR appearance of two human brains with Perls and Luxol fast blue stains indicates that the short T2 reflects heavy myelination and fiber density, not iron deposition. This is in contrast to the short T2 ...
Medtronic Inc. received FDA approval for its DBS System for Epilepsy on April 27, 2018.. The Medtronic Deep Brain Stimulation (DBS) System for Epilepsy is a device that delivers controlled electrical pulses to a location inside the brain which is involved in seizures. The system consists of a pulse generator (IPG) implanted under the skin of the upper chest, and two leads implanted in the brain. The system sends a constant stream of tiny electrical pulses through the leads to the electrodes in selected area of the brain; these impulses block seizures associated with epilepsy. The device helps reduce the frequency of seizures in patients who have frequent, disabling, partial-onset seizures, and have not responded well to antiepileptic medications.. The clinical trial SANTE (Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy) demonstrated that patients with the device turned on experienced a 17 percent greater reduction in the average number of seizures per month as compared to the ...
New results show a 69% mean reduction in seizure frequency 5 years after stimulation of anterior nuclei in patients with refractory epilepsy.
The symptoms of Parkinsons disease result from the loss of pigmented dopamine-secreting (dopaminergic) cells in the pars compacta region of the substantia nigra (literally black substance). These neurons project to the striatum and their loss leads to alterations in the activity of the neural circuits within the basal ganglia that regulate movement, in essence an inhibition of the direct pathway and excitation of the indirect pathway. The direct pathway facilitates movement and the indirect pathway inhibits movement, thus the loss of these cells leads to a hypokinetic movement disorder. The lack of dopamine results in increased inhibition of the ventral anterior nucleus of the thalamus, which sends excitatory projections to the motor cortex, thus leading to hypokinesia. There are four major dopamine pathways in the brain; the nigrostriatal pathway, referred to above, mediates movement and is the most conspicuously affected in early Parkinsons disease. The other pathways are the mesocortical, ...
Follicular development and ovulation are suppressed during lactation in various mammalian species, mainly due to the suppression of pulsatile GnRH/LH secretion. Metastin (kisspeptin-54), a KiSS-1 gene product, is an endogenous ligand for GPR54, a G-protein-coupled receptor, and suggested to play a critical role in regulating the gonadal axis. The present study therefore aims to determine whether metastin (kisspeptin-54)-GPR54 signaling in discrete brain areas is inhibited by the suckling stimulus that causes suppression of LH secretion in lactating rats. Quantitative RT-PCR revealed that the KiSS-1 mRNA level was significantly lower in the arcuate nucleus (ARC)-median eminence region in lactating ovariectomized (OVX) and estrogen-treated OVX rats than in nonlactating controls. KiSS-1 mRNA in the anteroventral periventricular nucleus was kept at a low level in both lactating and nonlactating rats despite estrogen treatment. GPR54mRNAlevels were significantly lower in lactating than nonlactating ...

To orient ourselves, we mainly need two pieces of information: where am I and in which direction am I heading? Experiments in the rat have shown that these types of information are directly accessible and independently coded in the brain. When the rat explores a new territory, so-called place cells and head direction cells form within only a few minutes. Place cells are active when the rat visits a particular area, no matter which direction it is facing. In contrast, head direction cells code the direction the rat is heading, independent of where it is. Also humans presumably have these and other types of cells which specifically instruct its sense of orientation. Scientists around Mathias Franzius and Laurenz Wiskott from the Humboldt-University and Bernstein Center for Computational Neuroscience Berlin (Germany) have now developed a theoretical model that can explain the emergence of all orientation-specific cells that are known in rats and primates to date.. Now my personal experience is that ...

The OP is inherently a less accurate plane to measure on account of the lack of precise landmarks. Zollikofer et al. (2005) and Brunet and Allemand (2005) did not provide details of how they measured the orientation of the OP, but judging from the illustrations it was obtained by drawing a vertical line in the middle of the orbit extending from the anterodorsal margin of the orbit to the antero-ventral edge of the orbit immediately beneath the former point. There are four main difficulties with this measurement, the first being that the left and right sides of the same skull may be different (in fact each orbit has its own OP). The second, and a more serious difficulty is that the upper and lower margins of the orbits are curved dorsoventrally (strongly) and mediolaterally (gently), and thus it is difficult to define precise points for consistent measurements between individuals or successive measurements in the same individual, and thus of obtaining reliable results for the orientation of the ...

Reply: We thank Duprez et al for their attention and valuable comments concerning our article Acute Korsakoff Syndrome Following Mammillothalamic Tract Infarction (1) and also for presentation of their advanced work in neuroradiology and neuromodulation (2, 3). Their excellent depictions of the mammillothalamic tract (MTT) and implanted neuromodulation electrodes with MR imaging allow us the opportunity to further discuss amnesia-initiating lesion(s) in our case.. Korsakoff syndrome is defined as a disproportionate impairment in memory, relative to other aspects of cognitive function, resulting from a nutritional (thiamine) depletion (4). In our case, however, the patient developed acute amnesia with features of Korsakoff syndrome that were not attributable to malnutrition but were the result of a left MTT infarction. MR imaging studies revealed acute ischemic damage of the left MTT assessed by diffusion-weighted imaging and a previous contralateral right MTT infarct on T2-weighted and ...

The role of the thalamus in high-level cognition-attention, working memory (WM), rule-based learning, and decision making-remains poorly understood, especially in comparison to that of cortical frontoparietal networks [1-3]. Studies of visual thalamus have revealed important roles for pulvinar and lateral geniculate nucleus in visuospatial perception and attention [4-10] and for mediodorsal thalamus in oculomotor control [11]. Ventrolateral thalamus contains subdivisions devoted to action control as part of a circuit involving the basal ganglia [12, 13] and motor, premotor, and prefrontal cortices [14], whereas anterior thalamus forms a memory network in connection with the hippocampus [15]. This connectivity profile suggests that ventrolateral and anterior thalamus may represent a nexus between mnemonic and control functions, such as action or attentional selection. Here, we characterize the role of thalamus in the interplay between memory and visual attention. We show that ventrolateral lesions impair
The laterodorsal nucleus (LDN) of the thalamus provides a prominent afferent projection to the postsubiculum (dorsal presubiculum). To characterize synaptic transmission in this pathway, we placed stimulating electrodes in the LDN and recorded fEPSPs elicited in the postsubiculum of urethane-anesthetized rats. LDN stimulation elicited a source-sink dipole between the deep and superficial layers of the postsubiculum, respectively, consistent with anatomical evidence for the termination of thalamic afferents in the superficial layers of the structure, and the existence of deep layer neurons with apical dendrites extending into these layers. Postsubicular fEPSPs were typically 0.5-1.0 mV in amplitude, with a peak latency of approximately 6 ms. Consistent with anatomical observations, the short onset latency of fEPSPs elicited by LDN stimulation, and their ability to follow a 60-Hz train of stimulation, indicate that the projection is monosynaptic. Paired-pulse stimulation revealed pronounced ...
The aims of this study were to i) identify substantia nigra subregions i.e. pars reticulata (SNr) and pars compacta (SNc), in human, and ii) to assess volumetric changes in these subregions in the diagnosis of Parkinsons disease. Current MR imaging techniques are unable to distinguish SNr and SNc. Segmentation of these regions may be clinically useful in Parkinsons disease (PD) as substantia nigra is invariably affected in PD. We acquired quantitative T1 as well as diffusion tensor imaging (DTI) data from ten healthy subjects and ten PD patients. For each subject, the left and right SN were manually outlined on T1 images and then classified into two discrete regions based on the characteristics of their connectivity with the rest of the brain using an automated clustering method on the DTI data. We identified two regions in each subjects SN: an internal region that is likely to correspond with SNc because it was mainly connected with posterior striatum, pallidum, anterior thalamus, and prefrontal

We aimed to test the hypothesis that lateral line placodes form both ampullary organs and neuromasts in cartilaginous fishes, by performing in vivo fate-mapping in the little skate. We used the fluorescent lipophilic dye DiI to label focally the anterodorsal lateral line placode alone, or the anterodorsal plus anteroventral lateral line placodes, in L. erinacea embryos at stage 25 (n=18). These placodes were selected because they are the largest cranial lateral line placodes, hence the easiest to target, and they give rise to both ampullary organs and neuromasts in the axolotl (Northcutt et al., 1995) and paddlefish (Modrell et al., 2011a). The anterodorsal and anteroventral lateral line placodes can both be recognized in skate embryos morphologically as thickenings of ectoderm caudal to the eye and dorsal to the mandibular and hyoid arches, respectively (Fig. 1D), and molecularly, by expression of the gene encoding the transcription co-factor Eya4 (Fig. 1E), an established marker of the ...
In Vivo Demonstration of Homonymous Hemimacular Loss of Retinal Ganglion Cells Due to a Thalamic Lesion Using Optical Coherence Tomography
This study was designed to determine whether the sympathetic nervous system exerts a protective or enhancing effect in acoustic overstimulation. The compound action potential of the cochlea (CAP) was recorded in guinea pigs while the cervical sympathetic nervous system (SNS) was electrically stimulated or after it was surgically eliminated. The stimulation or the elimination of the cervical SNS has no effect on the threshold of CAP. The threshold shift in CAP after acoustic overstimulation (110, 115, or 130 dB SPL for 10 min) was measured in the cervical SNS stimulation group, in the cervical SNS elimination group, and in the control group. When the animal was under insufficient sedation, there was no difference among these three groups. However, the CAP threshold shift was significantly smaller in the cervical SNS stimulation group than in the other two groups when the animals were sufficiently sedated. The cervical SNS stimulation had some protective effect on the susceptibility to acoustic trauma
The study did not meet the primary effectiveness outcome. The mean IDS-C 30-item change from baseline over weeks 10, 14, 18, and 22 (the Acute Phase) was not statistically different between the high dose and the low dose groups (Low vs. High stimulation group: P=0.8027) as well as between the medium dose and the low dose groups (Low vs. Medium stimulation group: P=0.8131).. Although on average the score for all 3 groups showed an improved score over time, this was not set as the primary study outcome and could be due to response to other treatments as well as natural course of the disorders or statistical regression to the mean, and perhaps to a placebo effect since the study was blinded to dosage but not to VNS Therapy implant. No statistically significant differences were noted between treatment groups for any of the effectiveness outcomes, in either of the study periods (Acure Phase or Long-term Phase ...

This thesis introduces a hierarchical model for unsupervised learning from naturalistic video sequences. The model is based on the principles of slowness and sparseness. Different approaches and implementations for these principles are discussed. A variety of neuron classes in the hippocampal formation of rodents and primates codes for different aspects of space surrounding the animal, including place cells, head direction cells, spatial view cells and grid cells. In the main part of this thesis, video sequences from a virtual reality environment are used for training the hierarchical model. The behavior of most known hippocampal neuron types coding for space are reproduced by this model. The type of representations generated by the model is mostly determined by the movement statistics of the simulated animal. The model approach is not limited to spatial coding. An application of the model to invariant object recognition is described, where artificial clusters of spheres or rendered fish are ...
In epigeic rodents, familiar landmarks exert primary control over a variety of spatial behaviors and related neural mechanisms (OKeefe and Nadel, 1978; Taube et al., 1990; Taube and Burton, 1995; Dudchenko et al., 1997; Sharp et al., 2001; Sharp, 2002). Nevertheless, a directional sense that is not linked to visual landmarks also appears to play a central role in many aspects of rodent spatial behavior and cognition (e.g. Knierim et al., 1995; Skinner et al., 2010; van der Meer et al., 2010). Species such as rats show a remarkable ability to place neural representations of different surroundings into register. When rats are transferred to an unfamiliar laboratory enclosure, directional properties of, for example, head direction cells and subicular place cells typically retain the same absolute alignment (Sharp and Green, 1994; Knierim et al., 1995; Taube and Burton, 1995; Dudchenko et al., 1997; Sharp, 1997; Sharp, 2002; Sharp et al., 2001), suggesting that these properties are transferred to ...
Montreal, QC. Introduction. An early symptom of Alzheimers disease is frequent disorientation in familiar settings, often resulting in patients getting lost on their routine commutes to work or home. What pathology in the brain causes this debilitating deficit in spatial cognition? Recent experiments have identified a neural circuit in the entorhinal cortex that is essential for spatial memory and navigation. This circuit contains three navigation-related neuronal types including `grid cells that track your movement through space (similar to a GPS), `head direction cells that act as the brains `internal compass, and `border cells that signal proximity to edges of the environment.. Objectives. We propose to test the hypothesis that a disruption of this entorhinal navigational circuit underlies the spatial memory and spatial cognition deficits reported in Alzheimers disease. The first objective is to identify whether the spatial firing patterns of neurons in this circuit undergo a ...
The objective of this trial is to demonstrate the efficacy and safety of pallidal DBS in HD patients, and show superiority of DBS on motor function in the stimulation group compared to stimulation-off group and that DBS is a good alternative to medication therapy. For ethical reasons all patients (including the controls) will receive best contact stimulation after assessment of the primary endpoint for 3 months and a final follow up is planned 6 month after study inclusion. All patients will receive a bilateral stereotactic insertion of quadripolar electrodes (Medtronic Inc, 3387) into the Globus pallidus (GP) for chronic high-frequency stimulation with the upper two contacts reaching the external GP (GPe) and the lower two contacts placed in the internal GP (GPi). The implantation of the stimulator (ACTIVA®PC) will take place in the same procedure. This approach has been successfully used in previous studies of DBS in dystonia. ...
OBJECTIVE: To evaluate the impact of a short-term neuromuscular electrical stimulation program on exercise tolerance in hospitalized patients with advanced heart failure who have suffered an acute decompensation and are under continuous intravenous inotropic support. DESIGN: A randomized controlled study. SUBJECTS: Initially, 195 patients hospitalized for decompensated heart failure were recruited, but 70 were randomized. INTERVENTION: Patients were randomized into two groups: control group subject to the usual care ( n = 35); neuromuscular electrical stimulation group ( n = 35) received daily training sessions to both lower extremities for around two weeks. MAIN MEASURES: The baseline 6-minute walk test to determine functional capacity was performed 24 hours after hospital admission, and intravenous inotropic support dose was daily checked in all patients. The outcomes were measured in two weeks or at the discharge if the patients were sent back home earlier than two weeks. RESULTS: After ...
