Topic: inter-laminar communication

Visual perception emerges from intricate interactions among neuronal populations across the brain's sensory processing hierarchy. Neuronal correlations in the visual cortex can be modulated by both external visual stimuli and internal states. Recent studies emphasize the role of communication subspaces as a population-level routing mechanism that serve as “channels” for transmitting information, facilitating coordinated activity across brain areas (e.g., V1-V2) or between cortical layers (e.g., input-superficial). It is however not known if this co-ordinated activity has directed or shared ori
