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: Using genetic engineering in mice, approximately 20 Cre and inducible CreER knockin driver lines that reliably target major classes and lineages of GABAergic neurons are generated, thereby enabling a systematic and comprehensive analysis from cell fate specification, migration, and connectivity, to their functions in network dynamics and behavior.

TL;DR: A representative group of researchers are convened to agree on a set of terms to describe the anatomical, physiological and molecular features of GABAergic interneurons of the cerebral cortex, and the resulting terminology might provide a stepping stone towards a future classification of these complex and heterogeneous cells.

TL;DR: Each subtype of cells made GABAergic synapses onto relatively specific portions of cortical cells, but similar domains were innervated by multiple classes of GABA cells.

TL;DR: It is suggested that the heterogeneity of both the core and co-morbid features predicts a heterogeneous pattern of neuropathology in autism, and defined phenotypes in larger samples of children and well-characterized brain tissue will be necessary for clarification of the neuroanatomy of autism.
