Barrel cortex function

TL;DR: This work reveals sparse and spatially intermingled representations of multiple tactile features in mice expressing GCaMP6s and nuclear red fluorescent proteins during performance of a single whisker object localization task and an encoding model related activity to behavioral variables.

TL;DR: Early spontaneous activity patterns control the formation of developing networks in sensory cortices, and disturbances of these activity patterns may lead to long-lasting neuronal deficits.

TL;DR: The potential for the use of known critical and sensitive periods during vertebrate development to investigate and advance the understanding of the neural bases underlying impairments in these developmental disorders of the nervous system is highlighted.

TL;DR: Making whole-cell recordings in primary somatosensory barrel cortex of behaving mice shows that S1 neurons projecting to primary motor cortex and those projecting to secondary somatoensory cortex have distinct intrinsic membrane properties and exhibit markedly different membrane potential dynamics during behavior.

TL;DR: It is suggested that a vibrissal column contains a central core zone intimately linked with the ventrobasal thalamus that is bounded by narrower regions of more diverse inputs and outputs that form an interface between adjacent cortical columns.

TL;DR: Juxtasomally recorded action potential patterns from excitatory cells in layer (L) 2/3, L4, L5 and L6 of rat barrel cortex in response to a standard stimulus, suggesting that these cells could direct sensory guided behaviours.

TL;DR: Data support the conclusion that in the rat, as in other species, SII and PV represent anatomically and functionally distinct areas of secondary somatosensory cortex.

TL;DR: It is proposed that mult isensory cortex be considered functionally distinct from SII, and that SII may be more concerned with unisensory processing tasks.
