Cortical microcircuit

Layer 3 — Biologyin the systems-neuroscience subtree

Canonical 6-layer column with stereotyped connectivity: L4 input, L2/3 feed-forward, L5 output, L6 thalamocortical feedback. Inhibitory interneurons (PV, SST, VIP) sculpt activity via distinct targeting. Basis of Hubel–Wiesel orientation…
