TL;DR: It is argued that in order to understand neocortical function one needs to combine a microscopic view, elucidating the workings of the local columnar microcircuits, with a macroscopic view, which keeps track of the linkage of distant cortical modules in different behavioral contexts.

Sleep Spindles: Mechanisms and Functions.
TL;DR: Their fine spatiotemporal organization reflects NREMS as a physiological state coordinated over brain and body and may indicate, if not anticipate and ultimately differentiate, pathologies in sleep and neurodevelopmental, -degenerative and -psychiatric conditions.

A Cellular Resolution Map of Barrel Cortex Activity during Tactile Behavior
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.
Sensitive and critical periods during neurotypical and aberrant neurodevelopment: a framework for neurodevelopmental disorders.
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.

Membrane potential dynamics of neocortical projection neurons driving target-specific signals.
Takayuki Yamashita,Aurélie Pala,Leticia Pedrido,Yves Kremer,Egbert Welker,Carl C.H. Petersen +5 more
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.

Reconstruction of an average cortical column in silico
TL;DR: The possibilities to obtain a model cortical column by using in vitro and in vivo pair recordings, followed by anatomical reconstructions of the projecting and target cells to establish connection modules that eventually may be useful to synthesize an average cortical column in silico are reviewed.
A functional microcircuit for cat visual cortex.
TL;DR: The microcircuit simulates with good fidelity the intracellular responses of neurones in cat visual cortex to electrical pulse stimulation of the cortical afferents and provides a novel explantation for the apparent lack of significant inhibition during visual stimulation.

TL;DR: Viral expression of the ratiometric Ca2+ sensor yellow cameleon 3.60 in pyramidal neurons of mouse barrel cortex enables in vivo measurement of neuronal activity with high dynamic range and sensitivity across multiple spatial scales, and opens a multitude of opportunities for functional studies of the neural basis of animal behavior.
Nonlinear encoding of tactile patterns in the barrel cortex
TL;DR: The temporal structure of cortical dynamics after a single deflection dictates the response to complex temporal patterns, which are more representative of stimuli encountered under natural conditions.
Task- and Subject-Related Differences in Sensorimotor Behavior during Active Touch
TL;DR: On two types of tactile discrimination tasks, macrogeometric and microgeometric, better performers palpated the discrimnanda for longer periods of time and used movement patterns that appeared to optimize whisking frequency bandwidth and the extent to which the vibrissae would be bent by object contact.
