Three-way inhibitive structure. (A) Average amount of connected PCs (green) and LBCs (blue) from a single PC per inter-somatic distance (avg. sum of neurons per distance surrounding a single PC). PC and LBC distributions and connectivity functions allow for Mexican hat shaped excitation, as connected PCs are generally closer than connected LBCs. (B) Illustration of structure topology. Activation of central PC immediately drives connected PCs while inhibiting others which are connected via basket cell lateral inhibition. It also inhibits its own local neighborhood within a certain delay, the effect attributed to Martinotti cells.
