Information And Control: Insights from within the brain [PDF]
arXiv, 2022 The neural networks of the brain are capable of learning statistical input regularities on the basis of synaptic learning, functional integration into increasingly larger, interconnected neural assemblies, and self organization. This self organizing ability has implications for biologically inspired control structures in robotics.

Thickening in the somatosensory cortex of patients with migraine [PDF]
Neurology, 2007 To examine morphologic changes in the somatosensory cortex (SSC) of patients with migraine.Cortical thickness of the SSC of patients with migraine was measured in vivo and compared with age- and sex-matched healthy subjects. The cohort was composed of 24 patients with migraine, subdivided into 12 patients who had migraine with aura, 12 patients who had

Respiratory rhythm entrains membrane potential and spiking of non-olfactory neurons [PDF]
arXiv, 2022 In recent years, several studies have tended to show a respiratory drive in numerous brain areas so that the respiratory rhythm could be considered as a master clock promoting communication between distant brain areas. However, outside of the olfactory system it is not known if respiration-related oscillation (RRo) could exist in the membrane potential

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.

Correspondence of MRI and nTMS With EDSS in Multiple Sclerosis: Longitudinal Follow‐Up Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Considering the characteristics of multiple sclerosis (MS) disease and its impact on motor disability, this study aims to assess the functional integrity of the corticospinal tract by examining motor evoked potentials (MEPs), Expanded Disability Status Scale (EDSS) scores, magnetic resonance imaging (MRI) lesion counts, and ...

Glia, Volume 71, Issue 2, Page 187-204, February 2023., 2023 Main Point Loss of oligodendrocyte ErbB receptor signaling leads to A1 hypomyelination, reduced PV expression and density of PV+ neurons and synapses, hypoconnectivity of inhibitory circuits and shift of the E/I balance towards excitation. Abstract For a long time, myelin was thought to be restricted to excitatory neurons, and studies on dysmyelination

Neural basis of somatosensory target detection independent of uncertainty, relevance, and reports
eLife, 2019 Research on somatosensory awareness has yielded highly diverse findings with putative neural correlates ranging from activity within somatosensory cortex to activation of widely distributed frontoparietal networks. Divergent results from previous studies

Diversity of Intrinsic Frequency Encoding Patterns in Rat Cortical Neurons -Mechanisms and Possible Functions [PDF]
, 2012 Extracellular recordings of single neurons in primary and secondary somatosensory cortices of monkeys in vivo have shown that their firing rate can increase, decrease, or remain constant in different cells, as the external stimulus frequency increases.

gACSON software for automated segmentation and morphology analyses of myelinated axons in 3D electron microscopy [PDF]
arXiv, 2021 Background and Objective: Advances in electron microscopy (EM) now allow three-dimensional (3D) imaging of hundreds of micrometers of tissue with nanometer-scale resolution, providing new opportunities to study the ultrastructure of the brain. In this work, we introduce a freely available Matlab-based gACSON software for visualization, segmentation ...

Cortical Excitability Before and After Long‐Term Perampanel Treatment for Epilepsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Antiseizure medications (ASMs), which may influence cortical excitability, are the mainstay of epilepsy treatment. Transcranial magnetic stimulation (TMS) helps evaluate cortical excitability. We assessed changes in TMS responses using serial TMS measurements in people treated with an adjunctive noncompetitive AMPA‐receptor ...
