Stimulus-induced causal interactions in the gamma range can flow in direction opposite to the canonical microcircuit, violating the notion that they are signatures of feedforward communication.
RORβ is a key layer 4 transcription factor orchestrating a critical juncture in barrel development where terminal differentiation and activity inputs are integrated to drive cellular organization in the cortex.
Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

Elaborate dendritic branch patterns lead to a local and branch-specific reduction in impedance, which attenuates back-propagating action potentials and limits voltage-gated calcium influx.
ATAC-seq, transcriptomics, and transcription factor motif searches collaborate to build a network that regulates gene expression in different cortical layers.
Subtypes of dendrite-targeting somatostatin cells segregate into separate networks by specifically connecting with neurons in different layers, forming circuits that could independently control different input pathways to the neocortex.

The areas of the cerebral cortex that are necessary for mice to perform goal-directed navigation differ depending on previous experience in cognitively challenging tasks.
