Frontiers in Physiology, 2018 The tiny ensemble of neurons in the leech ganglion can discriminate the locations of touch stimuli on the skin as precisely as a human fingertip. The leech uses this ability to locally bend the body-wall away from the stimulus. It is assumed that a three-

Proprioceptive and tactile processing in individuals with Friedreich ataxia: an fMRI study
Frontiers in Neurology, 2023 ObjectiveFriedreich ataxia (FA) neuropathology affects dorsal root ganglia, posterior columns in the spinal cord, the spinocerebellar tracts, and cerebellar dentate nuclei. The impact of the somatosensory system on ataxic symptoms remains debated.

"Morphological Classification of Galaxies Using SpinalNet," 2021 16th
International Conference on Electronics Computer and Computation (ICECCO),
Kaskelen, Kazakhstan, 2021, pp. 1-5, 2023 Deep neural networks (DNNs) with a step-by-step introduction of inputs, which is constructed by imitating the somatosensory system in human body, known as SpinalNet have been implemented in this work on a Galaxy Zoo dataset. The input segmentation in SpinalNet has enabled the intermediate layers to take some of the inputs as well as output of preceding

A Critical Period for the Rapid Modification of Synaptic Properties at the VPm Relay Synapse
Frontiers in Molecular Neuroscience, 2017 In addition to cortical areas, the thalamus also displays plasticity during a critical period in early life. Since most sensory information is transmitted to the cortex via the thalamus, it will be of significant interest to understand the precise time ...

Massive cortical reorganization in sighted Braille readers
eLife, 2016 The brain is capable of large-scale reorganization in blindness or after massive injury. Such reorganization crosses the division into separate sensory cortices (visual, somatosensory...).

Sensory supplementation system based on electrotactile tongue biofeedback of head position for balance control [PDF]
Neuroscience Letters 431, 3 (2008) 206-10, 2008 The present study aimed at investigating the effects of an artificial head position-based tongue-placed electrotactile biofeedback on postural control during quiet standing under different somatosensory conditions from the support surface. Eight young healthy adults were asked to stand as immobile as possible with their eyes closed on two Firm and Foam

Grip force as a functional window to somatosensory cognition [PDF]
2022, Frontiers in Psychology Section Cognition, 13:1026439, 2022 Analysis of grip force signals tailored to hand and finger movement evolution and changes in grip force control during task execution provide unprecedented functional insight into somatosensory cognition. Somatosensory cognition is the basis of our ability to act upon and to transform the physical world around us, to recognize objects on the basis of ...

Neuronal functional connectivity among multiple areas of the rat somatosensory system during spontaneous and evoked activities [PDF]
PLoS Computational Biology 06/2013, 2012 Small-World Networks (SWNs) represent a fundamental model for the comprehension of many complex man-made and biological networks. In the central nervous system, SWN models have been shown to fit well both anatomical and functional maps at the macroscopic level.

Journal of Comparative Neurology, Volume 531, Issue 2, Page 314-335, February 2023., 2023 The main objective of this work was to obtain detailed information on the distribution and localization of the spexin (Spx) system in the sea bass brain. To this purpose, we first identified and characterized the spx1 gene and analyzed its expression in the central nervous system (CNS) of the European sea bass by using quantitative Real‐Time Polymerase
