Barrel cortex function
Dirk Feldmeyer,Michael Brecht,Fritjof Helmchen,Carl C.H. Petersen,James F.A. Poulet,Jochen F. Staiger,Heiko J. Luhmann,Cornelius Schwarz +7 more
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.
Heiko J. Luhmann,Anne Sinning,Jenq-Wei Yang,Vicente Reyes-Puerta,Maik C. Stüttgen,Sergei Kirischuk,Werner Kilb +6 more
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.

Three-dimensional axon morphologies of individual layer 5 neurons indicate cell type-specific intracortical pathways for whisker motion and touch
Marcel Oberlaender,Zimbo S. R. M. Boudewijns,Tatjana Kleele,Huibert D. Mansvelder,Bert Sakmann,Christiaan P. J. de Kock +5 more
TL;DR: Based on anatomical reconstructions and previous measurements of spiking, the hypothesis that thick-tufted neurons in rat vibrissal cortex receive input of whisker motion from slender-tufts neurons onto their apical tuft dendrites and input of whisky touch from thalamic neurons on their basal dendrite is put forward.

Organizing Principles of Cortical Layer 6
TL;DR: Examination of the anatomical and physiological characteristics of different classes oflayer 6 neuron, each specialized to participate in distinct circuits, provides insight into the functional contributions of layer 6 neurons toward cortical information processing.
Intersubnuclear connections within the rat trigeminal brainstem complex.
TL;DR: It is suggested that most intersubnuclear axons originate in TBNC local-circuit neurons, though some originate in cells that project to midbrain and/or diencephalon, as well as other TBNC subnuclei.

Motor Cortex Gates Vibrissal Responses in a Thalamocortical Projection Pathway
Nadia Urbain,Martin Deschênes +1 more
TL;DR: Evidence is provided that the stimulation of the vibrissa motor cortex suppresses vibrissal responses in ZIv via an intra-incertal GABAergic circuit, which provides support for the proposal that sensory transmission operates via a top-down disinhibitory mechanism that is contingent on motor activity.
