Schematic view of migration routes used by PV neurons. The first step of each route shows the migration path while the right part depicts the invasion of the cortical plate. A: paths from the MGE (in purple) and the POA (in pink). B: the path from the VGZ (in green). MZ: marginal zone, CP: cortical plate, SP: subplate, IZ: intermediate zone, SVZ: sub-ventricular zone, I–VI: layers of the cortex. Colored areas represent the population of migrating neurons and arrows represent the movement the population is taking.
