Topic: superficial layers

Successful navigation requires knowledge of the specific locations of different objects. However, currently only an object-invariant signal was discovered, marking all objects at all locations (carried by object-vector cells in the superficial layers of the medial entorhinal cortex (MEC)). It is thus unknown where and if this general object signal is crossed with a signal for a specific location (as is carried by place cells in the hippocampus), and whether these two variables are encoded conjunctively. We hypothesized that if indeed the brain represents object × position in a conjunctive ma

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
