The role of sensory network dynamics in generating a motor program. (1/9)

Sensory input plays a major role in controlling motor responses during most behavioral tasks. The vestibular organs in the marine mollusk Clione, the statocysts, react to the external environment and continuously adjust the tail and wing motor neurons to keep the animal oriented vertically. However, we suggested previously that during hunting behavior, the intrinsic dynamics of the statocyst network produce a spatiotemporal pattern that may control the motor system independently of environmental cues. Once the response is triggered externally, the collective activation of the statocyst neurons produces a complex sequential signal. In the behavioral context of hunting, such network dynamics may be the main determinant of an intricate spatial behavior. Here, we show that (1) during fictive hunting, the population activity of the statocyst receptors is correlated positively with wing and tail motor output suggesting causality, (2) that fictive hunting can be evoked by electrical stimulation of the statocyst network, and (3) that removal of even a few individual statocyst receptors critically changes the fictive hunting motor pattern. These results indicate that the intrinsic dynamics of a sensory network, even without its normal cues, can organize a motor program vital for the survival of the animal.  (+info)

Neural mechanisms underlying co-activation of functionally antagonistic motoneurons during a Clione feeding behavior. (2/9)

The ability of some neural networks to produce multiple motor patterns required during different behaviors is a well-documented phenomenon. We describe here a dramatic transition from coordinated inhibition between two functionally antagonistic groups of motoneurons to their co-activation in the feeding neural network of the predatory mollusk Clione limacina. To seize its prey, Clione uses specialized oral appendages, called buccal cones, which are controlled by two groups of motoneurons: cerebral A (Cr-A) neurons controlling buccal cone protraction and cerebral B (Cr-B) neurons controlling buccal cone retraction. When Cr-A neurons are active, Cr-B neurons usually receive strong inhibitory inputs that terminate their firing, which leads to the full protraction and elongation of the buccal cones. We have found, however, that the Cr-A and Cr-B motoneurons sometimes burst simultaneously without any traces of inhibition in the Cr-B motoneurons. This transformation of the neural network activity from inhibitory interactions to co-activation presumably occurs during the late "extraction" period of the feeding behavior when buccal cones become partially retracted and rhythmically active. The transition from the inhibitory interaction to co-activation is controlled by the activity of a single pair of cerebral interneurons (Cr-Aint interneurons), which are electrically coupled to the Cr-A neurons and monosynaptically inhibit Cr-B neurons. Normally, the Cr-Aint interneurons are active along with Cr-A motoneurons and inhibit Cr-B motoneurons. During a period of co-activation, however, these interneurons do not produce spikes, thus allowing Cr-A motoneuron activation without inhibition of the Cr-B motoneurons.  (+info)

To support long-lasting autonomic operation of the platform, all mechanical, electronic and photonic components were designed to provide minimal weight, size and power consumption, while still providing high operational efficiency, accuracy of
In both cortices and sensory systems, information is represented and transmitted through the correlated activity of large neuronal networks. Methods borrowed from Statistical Physics and Machine Learning are powerful tools for characterizing the collective behavior of large systems and thus offer promising approaches to understand the activity of neuronal populations. In this talk I will show how the Maximum Entropy principle, applied to cortical in-vivo recording, allows for comparing the population behavior during wakefulness and deep sleep and eventually for identifying cell-assemblies, i.e. strongly co-activated groups of neurons that play a central role in memory consolidation. I will then use hidden layer models, point processes and "experimental" linear response theory to account for the non-linear stimulus processing in sensory networks such as the retina. These approaches allow for constructing high performing models of the retinal population response to visual stimuli and thus for ...
Correlations in sensory neural networks have both extrinsic and intrinsic origins. Extrinsic or stimulus correlations arise from shared inputs to the network and, thus, depend strongly on the stimulus ensemble. Intrinsic or noise correlations reflect biophysical mechanisms of interactions between neurons, which are expected to be robust to changes in the stimulus ensemble. Despite the importance of this distinction for understanding how sensory networks encode information collectively, no method exists to reliably separate intrinsic interactions from extrinsic correlations in neural activity data, limiting our ability to build predictive models of the network response. In this paper we introduce a general strategy to infer population models of interacting neurons that collectively encode stimulus information. The key to disentangling intrinsic from extrinsic correlations is to infer the couplings between neurons separately from the encoding model and to combine the two using corrections ...

Alzheimers disease is a progressive disorder, starting in certain areas and proceeding through the brain in a particular pattern. Specific brain regions may develop Alzheimers-like changes including the clumping of a protein fragment called beta-amyloid, ultimately forming amyloid plaques, a hallmark of the disease. Though amyloid clumping can first occur in certain brain areas, it appears to trigger more widespread damage to the brains circuitry - the pathways through which chemical and electrical signals are transmitted and brain areas are connected. Thus damage in the "upstream" brain areas hinders the ability of connected "downstream" brain areas from processing information correctly. This can lead to a loss of function related to the networks affected, for example sensory networks such as those needed for olfaction which is the sense of smell. Daniel Wesson, Ph.D., and colleagues plan to study how damage localized to cells in the nasal cavity behind the nose (called olfactory receptor ...

These outcomes serve to additional illustrate the importance of topographical restrictions on a global sign digesting feature of a sensory network, while also showing how wealthy spatio-temporal and oscillatory aspect can evolve from a fairly little amount ...

that need it most. To achieve this feat, the capillary sensory network relies on a protein (an ion channel) that detects increases in potassium during neuronal activity.. Increased activity of this channel facilitates the flow of ions across the capillary membrane, thereby creating a small electrical current that generates a negative charge - a rapidly transmitted signal - that communicates the need for additional blood flow to the upstream arterioles, which then results in increased blood flow to the capillaries, researchers said. Researchers also determined that if the potassium level is too high, this mechanism can be disabled, which may contribute to blood flow disturbances in a broad range of brain disorders.. "These findings open new avenues in the way we can investigate cerebral diseases with a vascular component," said Fabrice Dabertrand of University of Vermont. These findings were published in the journal Nature Neuroscience.. ...
The shells of tiny sea snails called pteropods, or "sea butterflies", are dissolving thanks to the acidification of sea water brought about to increasing levels of CO2 in the ocean, according to researchers from the British Antarctic Survey BAS).. A letter in Nature Geoscience titled Extensive dissolution of live pteropods in the Southern Ocean details the research, which according to BAS saw researchers examine "... an area of upwelling, where winds cause cold water to be pushed upwards from the deep to the surface of the ocean." Such areas are of interest because their waters are "... usually more corrosive to a particular type of calcium carbonate (aragonite) that pteropods use to build their shells.". A "saturation horizon" of 1000 metres is usually the depth at which ocean water becomes sufficiently corrosive to damage pteropod shells, but the sample taken by researchers came from just 200 metres down reached the same level of acidity.. BAS says "as a result of the additional influence of ...
Author Summary Dynamic gain, the amount by which features at specific frequencies in the input to a neuron are amplified or attenuated in its output spiking, is fundamental for the encoding of information by neural populations. Most studies of dynamic gain have focused on neurons without intrinsic degrees of freedom exhibiting integrator-type subthreshold dynamics. Many neuron types in the brain, however, exhibit complex subthreshold dynamics such as resonance, found for instance in cortical interneurons, stellate cells, and mitral cells. A resonator neuron has at least two degrees of freedom for which the classical Fokker-Planck approach to calculating the dynamic gain is largely intractable. Here, we lift the voltage-reset rule after a spike, allowing us to derive a complete expression of the dynamic gain of a resonator neuron model. We find the gain can exhibit only six shapes. The resonant ones have peaks that become large due to intrinsic adaptation and become sharp due to an intrinsic frequency. A

Encoded in the strings of DNA bases that make up the genomes of living species are codes that regulate, control, and describe all sorts of biological processes. The underpinnings of these codes lie in the base sequence-dependent micromechanical properties of DNA, which determine the degree to which the long, threadlike molecule fluctuates and how it responds to the proteins that control its processing and govern its packaging. In order to understand the mechanisms by which DNA base sequence and tightly bound proteins control the biophysical properties of the long, threadlike molecule, we have developed a coarse-grained model, in which the DNA base pairs are treated as rigid bodies subject to realistic, knowledge-based energy constraints, and computational techniques to determine the minimum-energy configurations, intrinsic dynamics, and looping/cyclization propensities of these molecules. The presentation will highlight some of the unique, sequence-dependent spatial information that has been ...

Motoneurons may be active in more than one phase. the picture below shows a simplified diagram, showing which neurons are active in any one phase ...

We combined technologies of multiple disciplines, including modern biophysics, electrophysiology, neuroethology, neuropharmacology and psychology, to explore the origin, evolution and brain mechanism of consciousness and cognitive processes. We are now mainly focused on the cognitive function of prefrontal lobe in rodent and non-human primate macaques and its involvement in certain mental and neurological diseases. We are also interested in the brain mechanism of psychological withdrawal from drug addiction. ...
BERMEL, Afghanistan - Down a dirt alley a half-mile from Forward Operating Base Boris, a no-frills bastion that houses several hundred U.S. and Afghan troops behind 10-foot-high, sand-filled walls with a pair of 145 mm mortars at the center, American soldiers slinked like cats on the prowl.
We propose a new mathematical modeling framework to investigate the transmission and spread of foot-and-mouth disease. Our models incorporate relevant biological and ecological factors, vaccination effects, and seasonal impacts during the complex interaction among susceptible, vaccinated, exposed, infected, carrier, and recovered animals. We conduct both epidemic and endemic analysis, with a focus on the threshold dynamics characterized by the basic reproduction numbers. In addition, numerical simulation results are presented to demonstrate the analytical findings.
All biological processes including perturbation-responses are inherently dynamic. Investigating the temporal behavior of these dynamic processes is an important part of biological research. With the advancement of technology and reduction in cost, study of time-series gene expression has become routine [1]. The objectives of these types of research cannot be achieved without appropriate computational algorithms and methods. For example, a targeted perturbation like drug treatment activates or inhibits certain molecules in the cellular system in a transient or sustained manner; however, if we ignore these intrinsic dynamics of molecular changes due to lack of analysis techniques, we may miss out critical biological findings.. To analyze time-series gene expression profiles, several approaches have been used which can be divided into two classes. One of the classes is conventional clustering algorithms such as hierarchical, k-means clustering and self-organizing maps, which do not consider any ...
Impaired awareness or denial of ones disorder. A significant problem in several kinds of strokes and in neuropsychiatric disorders such as schizophrenia and bipolar disorder. It is strikingly manifest when a person with a paralysed limb claims it is still functioning. [One of Professor Ramachandrans patients, who had suffered a stroke which had paralysed the left side of her body, refused to accept that her arm couldnt move. Even though lucid in every other aspect (including awareness of the fact that she had suffered a stroke) she claimed her left arm was carrying out tasks even though clearly it wasnt. An explanation may involve close analysis of the different roles of the left and right hemispheres of the brain.] ...
Accumulation of carbonate mud is minor on the Northwest Shelf (Western Australia), a broad (, 200-300 km wide), distally steepened, tropical carbonate ramp. It is negligible along most of the inner ramp (0 to 50 m water depth) owing to siliciclastic (riverine) input. It is also negligible along the mid (from 50 to 120 m) ramp, and where the entire ramp narrows to , 100 km, owing to constant reworking by storm waves and ocean swell. In these areas, carbonate mud is derived mostly from mechanical degradation of skeletal fragments, but this does not include calcified remains of calcareous green algae (e.g., Halimeda) although these plants grow locally. Only along the outer (120 to 200 m water depth) ramp and slope is there any relatively abundant accumulation of carbonate mud. Here the sediment consists of modern pelagic (foraminifer, pteropod, and nannoplantkon) ooze and aragonitic needle-rich (, 2 μm) micrite, the latter having an age (based on AMS 14C) of ~ 19 ka. Distribution of aragonite ...
