We have demonstrated that volume of the head and body of the caudate nucleus differs significantly and substantially (ranging from 93% to 75% of control caudate volumes) in subtypes of FTLD. We also found that caudate nucleus volume was correlated with cognition measured via MMSE score, with lower volume correlating with poorer cognition. This finding complements previous meta-analyses showing functional and structural change in the caudate within subtypes of FTLD as well as in cortical regions.1. Krishnamoorthy30 has postulated that increase in volume of brain structures associated with emotion, such as the amygdala, may reflect either a predilection for emotional reactivity or plasticity and growth of the structure due to hyperactivity. The corollary is that neurodegenerative processes may result in atrophy and underactivity of the structure. Therefore, the caudate may be reduced in volume due to underactivity and/or degeneration as part of the FTLD process. That smaller caudate nucleus volume ...

The cat caudate nucleus has been reported to possess a rich and fairly even distribution of nerve endings, containing both dopamine- and cholecystokinin-like peptides. In this study, the effect of cholecystokinin-octapeptide (CCK-8) on basal and electrically evoked tritium outflow from slices of cat caudate nucleus previously labeled with [3H]dopamine was examined. Evoked tritium outflow from slices of cat caudate nucleus was Ca2+ dependent and abolished by tetrodotoxin, suggesting that it reflects action potential-induced [3H]dopamine release. In the presence of bovine serum albumin and bacitracin, the sulfated but not the unsulfated form of CCK-8 inhibited both basal and electrically evoked tritium outflow from slices of cat caudate nucleus at very low concentrations. CCK-8 sulfate was efficient in causing this effect in concentrations down to 10(-14) M, and the maximum effect was obtained with 10(-11) M. In contrast, without bovine serum albumin and bacitracin, no inhibitory effect of CCK-8 ...

The caudate nucleus is one of three basic structures that make up the basal ganglia. Along with the putamen and globus pallidus, as well in conjunction with the thalamus and two related structures (the substantia nigra and subthalamic nucleus), the caudate nucleus constitutes a system that is responsible largely for voluntary movement. While this system has long been associated with motor processes due primarily to the basal ganglias role in Parkinsons disease, there is mounting evidence that the structures that make up the basal ganglia-the caudate nucleus included-play important roles in various other nonmotor functions as well. Organizationally, the interplay between the basal ganglia and various regions in the brain is best described as a series of cortico-striatal loops, in which the striatum receives axons from the cortex (along with the putamen, the caudate nuclei are the main input regions for the basal ganglia), processes the information, then relays this back to distinct cortical ...

To test the hypothesis that craving for alcohol in the alcohol-dependent individual is mediated by a limbic circuit involving the caudate nuclei, regional cerebral blood flow was measured with [99mTc]HMPAO SPECT during control and craving conditions in 9 alcohol-dependent subjects. In all subjects, blood flow in the head of the right caudate nucleus increased during the craving condition, and these blood flow increases were strongly correlated with the experimentally induced increases in craving for alcohol. These new findings suggest a functional role for the limbic striatum in the mediation of craving and impaired control over alcohol consumption.

Love. Brain imaging has to be interpreted with some degree of care; the relationship between brain and mind is only beginning to emerge. With that caution, some interesting results. The madly in love infatuation phase doesnt actually seem to involve the emotional brain. Instead, it heavily involves the motivation and reward areas of the brain (dopamine heaven). Its only later, as a relationship matures, that the regions of the brain associated with emotion become more involved. (Personal note: This supports a belief Ive long held, Im sure in common with many readers, that the strongest long-term relationships start off as gradually-deepening friendships.) Said another way, the wild infatuation phase has much more in common with powerful drives like hunger and thirst than with the complexities and satisfactions of love in the long term. An aside to gratify a certain segment of the SBAA membership, the same regions activated when madly in love - the right caudate nucleus and the right ...

By Luke Davies. Follow Luke on Twitter.. A recent article in the New York Times has advocated extending the notion of personhood, and the rights associated with that status, to dogs. Gregory Burns, the author of the article, argued for this position on the basis of the structural and functional similarity between the caudate nucleus of dogs and humans. The caudate nucleus, Burns tells us, is that part of the brain responsible for our feeling of anticipation of things we enjoy. More than this, the activity of the caudate nucleus is so consistent in MRI scans that he claims we may be able to use our monitoring of its activity to predict our tastes for certain things (he lists music, food and beauty). Importantly for Burns, activity in the caudate increased in dogs in response to positive stimulus: a gesture signaling food, or the appearance of the owner. The tentative conclusion to these findings is that the MRI images signal the possibility of canine emotion. Burns makes clear that without the ...

Contemporary associative theory distinguishes between habitual S-R associations and a combination of S-O, O-R, and R-O associations thought to mediate goal-directed performance (Balleine and Ostlund, 2007). In this study, we used multivariate pattern analysis to assess whether dissociable regions of the human brain encode these distinct associative structures. Unlike previous work in humans, contrasting qualitatively different experimental conditions designed to encourage different action-selection strategies, or comparing largely parameter-driven value signals generated by RL algorithms, our approach sought to identify a neural implementation of the associative content of goal-directed versus habitual behavioral control. We found evidence for stimulus-elicited response representations but no outcome representations, indicative of habits, in the DLS (posterior putamen). Conversely, in the vmPFC, dlPFC, and anterior caudate nucleus, both response and outcome representations were present, ...

By comparison with these reports our results demonstrate a different pattern of hyperechogenic lesions in Huntingtons disease, primarily affecting the caudate nucleus and the substantia nigra. Considering different basal ganglia regions, hyperechogenic lesions of the substantia nigra were detectable in Huntingtons disease half as often as reported previously in Parkinsons disease.9 The rate of hyperechogenic lesions of the caudate nucleus was similar in Huntingtons disease and dystonia. Nevertheless, we found a considerably high signal intensity in most patients showing caudate nucleus hyperechogenic lesions, possibly pointing towards the predominant localisation of neuronal loss, whereas hyperechogenic lesions of the caudate nucleus in dystonia were described as mild. The precise morphological and pathological interpretation of basal ganglia hyperechogenicity demonstrated by TCS is still speculative. The fact that in the present study hyperechogenic lesions of the caudate nucleus were ...

There is still considerable controversy regarding the influence of blood viscosity upon CBF. We have measured CBF with microspheres in 23 cats. Autoregulation was disturbed in the left caudate nucleus by microsurgical occlusion of the left middle cerebral artery. Induced hypertension or hypotension was used and i.v. mannitol (1 g/kg) administered. In all cats blood viscosity decreased an average of 16% at 15 minutes and, in 16 cats, increased 10% at 75 minutes post-mannitol. CBF in the right caudate was 79 +/- 6 ml/100g/min, in the left 38 +/- 6 (p less than 0.001). Only minor changes of CBF occurred in areas with presumed normal autoregulation, including the right caudate, in conjunction with pressure or viscosity changes. In the left caudate CBF decreased 21% with hypotension and 18% with higher viscosity, more than on the right (p less than 0.01 and p less than 0.2, respectively). CBF increased in the left caudate 56% with hypertension and 47% with lower viscosity, again much more than on the ...

Methods 25 NOTCH3 mutation carriers and 18 healthy controls were examined using high-resolution T2*-weighted imaging on a 7 T whole body MRI scanner. Susceptibility-weighted MRI scans were analysed for areas of signal loss and increased phase shift. Phase shift measurements in deep grey nuclei, cortex and subcortical white matter were compared between mutation carriers and controls. For confirmation, ex vivo brain specimens from another three patients with CADASIL were analysed for iron deposition using ex vivo MRI combined with iron histochemistry.. ...

Huntingtons disease (HD) pathology is well understood at a histological level but a comprehensive molecular analysis of the effect of the disease in the human brain has not previously been available. To elucidate the molecular phenotype of HD on a genome-wide scale, we compared mRNA profiles from 44 human HD brains with those from 36 unaffected controls using microarray analysis. Four brain regions were analyzed: caudate nucleus, cerebellum, prefrontal association cortex [Brodmanns area 9 (BA9)] and motor cortex [Brodmanns area 4 (BA4)]. The greatest number and magnitude of differentially expressed mRNAs were detected in the caudate nucleus, followed by motor cortex, then cerebellum. Thus, the molecular phenotype of HD generally parallels established neuropathology. Surprisingly, no mRNA changes were detected in prefrontal association cortex, thereby revealing subtleties of pathology not previously disclosed by histological methods. To establish that the observed changes were not simply the ...

People are not born with this mental illness. Rather, they inherit the genetic predisposition to developing it. People can inherit a tendency for psychosis but not specific forms of schizophrenia.[5] Rather than thinking of the root of psychiatric disabilities as only set genes that cannot be changed, the cause should be viewed as activated genes which lead to certain neural circuits that subsequently produce symptoms. Treatments can be helpful and effective by modifying these neural circuits and strengthening brain functioning.. Baxter et al. (1992) proved that psychotherapy affects brain functioning. Clients with obsessive-compulsive disorder have metabolic disturbances in the caudate nucleus of the basal ganglia of their brains, which is proven through PET scans. However, behavioral treatment of exposure and response-prevention treatment normalize the functioning of peoples caudate nucleus.[6]. While this example is not specific to schizophrenia, it is relevant by proving that treatments ...

In the absence of visual input, the question arises as to how complex spatial abilities develop and how the brain adapts to the absence of this modality. As such, the aim of the current study was to investigate the relationship between visual status and an important brain structure with a well established role in spatial cognition and navigation, the caudate nucleus. We conducted a volumetric analysis of the caudate nucleus in congenitally and late blind individuals, as well as in matched sighted control subjects ...

The performances of 12 patients with Parkinsons disease (PD), 16 with Huntingtons disease (HD), and young and old healthy controls were assessed on a number of tests of verbal and nonverbal declarative memory, on a test of nonmotor conditional associative learning (words and colors), and on a number of reaction time (RT) tasks. The RT tasks consisted of cued simple and choice reactions. The relationship between the precue and the imperative stimulus in the S1-S2 paradigm was nonarbitrary in the first series and arbitrary in the second series. The series with arbitrary S1-S2 associations was repeated across two successive blocks of trials. The rationale of the study was to investigate the function of the basal ganglia complex loop, and it was postulated that HD patients would show greater deficits because of greater involvement of the caudate nucleus. The patients with HD had the slowest RTs. Across the two blocks with arbitrary S1-S2 associations, the patients with HD but not PD nevertheless ...

ASPERGERS SYNDROME LESSON. Directions:. Print the Aspergers Syndrome reading comprehension passage and questions (see below).. Students should read the passage silently, then answer the questions. Teachers may also use the text as part of a classroom lesson plan.. Lesson Excerpt. Aspergers Syndrome is a disorder in which people have extreme difficulty with social interaction. There is much more to it than just being shy around other people. This disorder is severe to the point that it causes major problems socially, at work, and in other areas of life. Many cases of Aspergers Syndrome go undetected. It was not even recognized as a disorder until 1994.. There are many symptoms of Aspergers Syndrome. A person may have difficulty using nonverbal gestures like eye contact, facial expression, and body posture. There may be difficulty in developing relationships with peers. A person may not seek to enjoy things with other people. He/she may be socially or emotionally unresponsive.. People with ...

Every year I read several manuscripts written by mothers about having a child with Aspergers syndrome. The quality of manuscripts varies considerably. As soon as I started to read Living Your Best Life with Aspergers syndrome I knew it was going to be one of my favourite biographies.

advice on what/how to tell your child.. As parents/teachers of children with Aspergers Syndrome we are expected to source all this information on our own. And so begins the Aspergers Syndrome journey - endless hours spent trawling the Internet; reading every book in your local library and filing every piece of information relevant to Aspergers Syndrome in your head for future reference. Only when youve upskilled and become enormously knowledgeable about Aspergers Syndrome can you finally match up the characteristics of AS with how those characteristics present in your child/student. Once the initial shock and disbelief settles, then you begin negotiating with your childs school (or parents of the child) over the best support strategies and accommodations to implement to give the AS child the greatest chance of success. This process usually takes somewhere between 10 and 18 months after diagnosis to complete. Were so busy upskilling ourselves as ourselves as parents/teachers during this ...

We describe an atypical neuropatholgical phenotype of sporadic Creutzfeldt-Jakob disease (sCJD) in a 64-year-old man presenting with a 5-month history of rapidly progressive dementia, comprising behavioral disturbances, memory complaints, disorientation and language alterations. MRI showed diffuse atrophy and hyperintensities in parietal, occipital, temporal and frontal cortices and left caudate nucleus on T2-weighted and fluid-attenuated inversion recovery images. No typical EEG alterations were observed. Repeated 14-3-3 assay was positive after a first negative test. Neuropathology showed classical CJD changes with small cortical foci of large confluent vacuoles and relatively well-preserved cerebellar cortex. The most striking feature was the presence of abundant Kuru-type plaques in both cerebral cortex and subcortical white matter. Sparse Kuru-type plaques were also seen in cerebellum, although only in white matter. Immunohistochemistry showed, in addition to unicentric plaques, diffuse ...

Tourette Syndrome (TS) is a developmental disorder of childhood characterized by motor and vocal tics. Patients with TS have decreased volume of the striatum (a region of the basal ganglia composed by caudate and putamen), and the decrease in caudate volume in childhood is inversely correlated with the severity of symptoms in adulthood. We have shown a large decrease in density of three classes of striatal interneurons in the striatum of TS: Parvalbumin+-GABAergic; NOS+/NPY+/SST+-GABAergic; and cholinergic (Kalanithi et al, 2005; Kataoka et al, 2010). Transcriptome analysis revealed a corresponding decreased expression of 308 genes encompassing genes related to these three classes of interneuron and inhibitory neurotransmission in general, as well as an up-regulation of 822 genes representing inflammatory response- and immune system-related genes (Lennington et al., 2014). Current studies in the lab aim to analyze genetic and epigenetic differences in the striatum and cortex as a whole and ...

The zone in which the posterior limb of the internal capsule reaches the cortex is an especially interesting point. Since the posterior limb is a perfectly flat sheet in the model in a plane exactly parallel to the median sagittal plane, it reaches the cortex in the upper third of the central convolutions. Thus in a transverse section the posterior limb corresponds to the lateral border of the tail of the caudate nucleus, and the fibres first medullated are projected straight to the cortex in a sagittal plane parallel to the median sagittal plane and exactly midway between the edge of the lateral ventricle and the surface of the island of Reil. In the adult brain the plane of the primitive posterior limb of the internal capsule can be demonstrated by making a sagittal section along the lateral border of the caudate nucleus to the point where it curves around into the roof of the lateral ventricle. In all of the models there is a curious band labeled no. 37 on the cortical radiation at the ...

Aspergers syndrome (AS) is one of the pervasive developmental disorders-a group of neurodevelopmental conditions of early onset characterized by impairments in social interaction and communication, and by restricted interest and behaviors. This chapter provides an overview of the historical and research background of AS leading to current debates; the changing nature of this discussion given the transformative changes in autism research in general in the past decade; the unchanging nature of these individuals needs whether or not the term survives new updates in psychiatric classification; and suggestions for a future more likely to clarify old questions while raising new and more scientifically helpful ones. To anchor this discussion in clinical realities, an overview of clinical features, treatment, and support services is also provided.

It is well-known that social influences affect consumption decisions. We used functional magnetic resonance imaging (fMRI) to elucidate the neural mechanisms associated with social influence with regard to a common consumer good: music. Our study population was adolescents, age 12-17. Music is a common purchase in this age group, and it is widely believed that adolescent behavior is influenced by perceptions of popularity in their reference group. Using 15-s clips of songs from MySpace.com, we obtained behavioral measures of preferences and neurobiological responses to the songs. The data were gathered with, and without, the overall popularity of the song revealed. Song popularity had a significant effect on the participants likability ratings of the songs. fMRI results showed a strong correlation between the participants rating and activity in the caudate nucleus, a region previously implicated in reward-driven actions. The tendency to change ones evaluation of a song was positively ...
