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.

Spontaneous Neuronal Activity in Developing Neocortical Networks: From Single Cells to Large-Scale Interactions.

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.

TL;DR: It is suggested that the interaction between movement-triggered sensory feedback signals and self-organized spindle oscillations shapes the formation of cortical connections required for sensorimotor coordination.

The Largest Group of Superficial Neocortical GABAergic Interneurons Expresses Ionotropic Serotonin Receptors
TL;DR: Fast modulation of serotonergic and cholinergic transmission may influence cortical activity through an enhancement of GABAergic synaptic transmission from 5-HT3AR-expressing neurons during sensory process depending on different behavioral states.

'Where' and 'what' in the whisker sensorimotor system.

TL;DR: Recent evidence is presented about how the brain constructs a representation of the surrounding world through whisker-mediated sense of touch and how the transformation of one representation to another is achieved.

Target-cell-specific facilitation and depression in neocortical circuits
TL;DR: In this article, the authors made simultaneous recordings from three classes of neurons in cortical layer 2/3, and induced repetitive action potentials in pyramidal cells and recorded the evoked unitary excitatory (E)PSPs in two classes of GABAergic neurons.

TL;DR: The results show that perceptual decisions and learning can be driven by extremely brief epochs of cortical activity in a sparse subset of supragranular cortical pyramidal neurons in mouse primary somatosensory cortex.
