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: The results suggest that the POm is functionally segregated into anterior and posterior parts and that the 2 parts may play different roles in somatosensory information processing.

TL;DR: It is demonstrated that ZI gates peripheral inputs to POm, enabling it to function both as a first-order and higher-order nucleus, and this gating mechanism may exert similar regulation of thalamic processing in other sensory systems.

TL;DR: This review summarizes recent knowledge of the maturation of various aspects of the GABAergic systems, like functional expression of GABA synthesizing/degrading enzymes and transporters, density of GABAergic synapses, GABAergic projection patterns, GABA receptor subunit composition, and properties ofGAergic interneurons, with an emphasis on the late developmental alterations.

TL;DR: Property of antidromically identified efferent neurons within the cortical representation of the vibrissae, sinus hairs, and philtrum were examined in motor cortex of fully awake adult rabbits to demonstrate their receptive field and axonal properties.
