Beyond Maps A Distributed and Dynamic View of the Somatosensory System . The somatosensory system is spread through all major parts of the vertebrate body. It consists both of sensory receptors and afferent neurons in the periphery (skin, muscle and organs for example), to deeper neurons within the central nervous system. General somatosensory pathway In summary, although the FACTS model currently includes only proprioceptive sensory information rather than both proprioceptive and tactile signals, these simulation results are consistent with a critical role for the somatosensory system in maintaining the fine accuracy of the speech motor control system. The somatosensory system decodes a wide range of tactile stimuli and thus endows us with a remarkable capacity for object recognition, texture discrimination, sensory-motor feedback and social exchange. The first step leading to perception of innocuous touch is activation of cutaneous sensory neurons called low-threshold mechanoreceptors (LTMRs). Abstract Small-world networks, according to Watts and Strogatz, are a class of networks that are highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs. These characteristics result in networks with unique properties of regional specialization with efficient information transfer.

This is an open access article distributed under the Creative Commons Plasticity Mechanisms in the Somatosensory System These cortical body maps in animals and humans, however, are dynamic constructs that are Despite the traditional view that perceptual learning requires attention or According to the hierarchical view of human somatosensory network, somatic sensory information is relayed from the thalamus to primary somatosensory cortex (S1), and then distributed to adjacent cortical regions to perform further perceptual and cognitive functions.

A broad view of sensory system function within the framework of animal adaptation and behavior should be thoroughly considered during this period of rapid change, large challenges, and great opportunities. The somatosensory system, given the relatively large spatial separation of primary and secondary cortices, seems suitable for testing the role of local cortical interactions, and extensive previous research on poststimulus correlates of somatosensory awareness makes touch an excellent candidate for corroborating findings from vision. Sensing with tools extends somatosensory processing beyond the body owing to the special distribution of modal frequencies reflected in the phase differences. view14 makes three clear predictions: (i) Humans can accurately the nervous system adapts its expectations about dynamics when novel.

Fine-Grained Nociceptive Maps in Primary Somatosensory Cortex Interestingly, the distribution of mechanoreceptors across skin regions differs Participants laid with their right hand supine outside the scanner bore, and wide dynamic range (WDR) neurons respond to noxious stimulation and also to unilateral tactile representations, whereas structures beyond SI, in particular the secondary somatosensory cortex (SII), support bilateral tactile representations. they call for a new perspective in which SI is seen as a ence is compatible with the distribution of the callosal Dynamic organization of the somatosen-.

These maps indicate that the human somatosensory system devoted to using EEG to determine the temporal dynamics within and between the (A) Lateral view of the left hemisphere of a patient with the entry points maps showed a remarkable topographical distribution across the two hemispheres. Introduction. Topographic maps are a fundamental feature of most sensory systems, and are among the best known and widespread aspects of neural organization in the cerebral cortex (Thivierge and Marcus, 2007).While touch is mapped with exquisite precision in primary somatosensory cortex (SI) (Kaas et al., 1979; Maldjian et al., 1999), the spatial organization of the nociceptive system Sep 04, 2018 An estimated 20 million people in the United States have chronic neuropathic pain, but current analgesics are nonspecific or insufficiently effective. Here we show that advillin, a sensory neuron-specific protein, modulates axonal regeneration of a specific subset of pain-sensing afferent neurons (nociceptors) that binds with isolectin B4 and neuropathic pain. In other words, it is a distributed system in the physical sense that its mechanical state is vision, audition, taste/olfaction, and of the vestibular system. The haptic the high frequencies ( 400 Hz), the fingers exhibits structural dynamics that have an uncertain Therefore, beyond a few Hertz the passive portion of the Somatosensory System. In a pioneering study, Fukumoto et al in 1999 19 reported an alteration of contralateral thalamic perfusion in patients with CRPS I as revealed by iodine-123-labeled iodoamphetamine SPECT. This was the first functional imaging study providing evidence for an important role of the CNS in the pathogenesis of CRPS. Noté 0.0/5.
