Anatomy of the sulcus septomedialis and medial cortex. (A) Transverse section through the telencephalon, stained with hematoxylin and eosin (red line = level of section), yellow box indicates position of (B). (B) Location of the sulcus septomedialis and medial cortex. The ventricular zone of the sulcus septomedialis is separated from the neuron-rich cellular layer of the medial cortex by a cell-sparse inner plexiform layer. The outer plexiform layer separates the cellular layer from the pial surface of the brain. Scale bar: 20 μm. advr = anterior dorsal ventricular ridge, cl = cellular layer, dc = dorsal cortex, dmc = dorsal medial cortex, ipl = inner plexiform layer, lc = lateral cortex, mc = medial cortex, opl = outer plexiform layer, sp = septum, vz = ventricular zone.
