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.

Impact of somatostatin interneurons on interactions between barrels in plasticity induced by whisker deprivation
TL;DR: In this paper , the authors used a spared vibrissa paradigm to visualize the plasticity formation induced by sensory deprivation in adult mice (2-3 months old) using a [14C]-2-deoxyglucose mapping of the spared whisker.

TL;DR: This study reveals the retrosplenial cortex plays a crucial role in context-dependent goal-directed sensorimotor transformation, enabling mice to adjust behavioral responses to stimuli based on contextual cues, and is the first cortical area to show context discrimination.
Neocortical dynamics during whisker-based sensory discrimination in head-restrained mice
TL;DR: These findings provide first glimpses of cortico-cortical communication but emphasize that for understanding the complete process of discrimination it will be crucial to elucidate the details of how neural processing is coordinated across brain-wide neuronal networks including the S1-S2-M1 triangle and cortical areas beyond.
A somatosensory circuit for cooling perception in mice.
Nevena Milenkovic,Wen-Jie Zhao,Jan Walcher,Tobias Albert,Jan Siemens,Gary R. Lewin,James F.A. Poulet +6 more
TL;DR: The results identify parts of a neural circuit underlying cold perception in mice and provide a new model system for the analysis of thermal processing and perception and multimodal integration.
Projection-specific Activity of Layer 2/3 Neurons Imaged in Mouse Primary Somatosensory Barrel Cortex During a Whisker Detection Task

- 01 Jan 2020
TL;DR: The hypothesis that communication between primary and secondary somatosensory cortex might be an early critical step in whisker sensory perception is supported and the importance of investigating projection-specific neuronal activity in distinct populations of intermingled excitatory neocortical neurons during task performance is suggested.

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.
