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.

Mapping the brain-wide network effects by optogenetic activation of the corpus callosum
Y Chen,Y Chen,Filip Sobczak,Filip Sobczak,Patricia Pais-Roldán,Patricia Pais-Roldán,Cornelius Schwarz,Alan P. Koretsky,Xin Yu,Xin Yu +9 more
TL;DR: The need of fMRI to elucidate the brain-wide network activation in response to projection-specific optogenetic stimulation is raised, and the calcium-amplitude modulation (AM)-based correlation with whole-brain fMRI signal revealed that the inhibitory effects spread to contralateral BC as well as ipsilateral MC and PO.

TL;DR: Spatial attention elevates neuronal activity in the primary vibrissal cortex of mice, dissociating attention from arousal.
Neural coding in barrel cortex during whisker-guided locomotion
Nicholas James Sofroniew,Yurii A. Vlasov,Yurii A. Vlasov,Samuel Andrew Hires,Jeremy Freeman,Karel Svoboda +5 more
TL;DR: Neural coding in the barrel cortex of head-fixed mice that tracked walls with their whiskers in tactile virtual reality revealed that barrel cortex plays a role in wall-tracking, and closed-loop optogenetic control of layer 4 neurons can substitute for whisker-object contact to guide behavior resembling wall tracking.
Selection of head and whisker coordination strategies during goal-oriented active touch.
TL;DR: It is suggested that mice can select from a diverse range of sensing strategies incorporating both knowledge of the task and whisk-by-whisk sensory information and the existence of high level control (not solely reflexive) of sensing motions coordinated between multiple body parts is suggested.
Olfactory Development, Part 2: Neuroanatomic Maturation and Dysgeneses.
TL;DR: Cellular markers of neuronal differentiation and synaptogenesis demonstrate immaturity of the olfactory system at birth, previously believed by histology alone to occur early in fetal life.

Distributed Hierarchical Processing in the Primate Cerebral Cortex
TL;DR: A summary of the layout of cortical areas associated with vision and with other modalities, a computerized database for storing and representing large amounts of information on connectivity patterns, and the application of these data to the analysis of hierarchical organization of the cerebral cortex are reported on.

TL;DR: The timing of a sensory input relative to a gamma cycle determined the amplitude and precision of evoked responses and provided the first causal evidence that distinct network activity states can be induced in vivo by cell-type-specific activation.
