Neuronal Activity in Rat Barrel Cortex Underlying Texture Discrimination
Rats and mice palpate objects with their whiskers to generate tactile sensations. This form of active sensing endows the animals with the capacity for fast and accurate texture discrimination. The present work is aimed at understanding the nature of the underlying cortical signals. We recorded neuronal activity from barrel cortex while rats used their whiskers to discriminate between rough and ...
متن کاملExcitatory neuronal connectivity in the barrel cortex
Neocortical areas are believed to be organized into vertical modules, the cortical columns, and the horizontal layers 1-6. In the somatosensory barrel cortex these columns are defined by the readily discernible barrel structure in layer 4. Information processing in the neocortex occurs along vertical and horizontal axes, thereby linking individual barrel-related columns via axons running throug...
متن کاملModulatory Effects of Memantine on Neuronal Response Properties in Rat Barrel Cortex
Introduction: Memantine as N-Methyl-D-aspartic acid (NMDA) receptor antagonist is used in some neurological disorders. It has been reported that memantine has modulatory effects on the somatosensory information processing in healthy subjects. This study investigated the effect of memantine on electrophysiological properties of barrel cortex neurons in male rats. Methods: Single unit recording ...
متن کاملEffects of Dimethyl Sulfoxide on Neuronal Response Characteristics in Deep Layers of Rat Barrel Cortex
Introduction: Dimethyl sulfoxide (DMSO) is a chemical often used as a solvent for waterinsoluble drugs. In this study, we evaluated the effect of intracerebroventricular (ICV) administration of DMSO on neural response characteristics (in 1200–1500 μm depth) of the rat barrel cortex. Methods: DMSO solution was prepared in 10% v/v concentration and injected into the later...
متن کاملRORβ induces barrel-like neuronal clusters in the developing neocortex.
Neurons in layer IV of the rodent whisker somatosensory cortex are tangentially organized in periodic clusters called barrels, each of which is innervated by thalamocortical axons transmitting sensory information from a single principal whisker, together forming a somatotopic map of the whisker pad. Proper thalamocortical innervation is critical for barrel formation during development, but the ...
