subcallosal gyrus(redirected from peduncle of corpus callosum)
a slender vertical whitish band immediately anterior to the lamina terminalis and anterior commissure; despite its name, it is not a cortical convolution but is the ventral continuation of the transparent septum. The small ridge of tissue immediately rostral to the lamina terminalis is sometimes designated as a separate part of the subcallosal area and called the paraterminal gyrus [TA] (gyrus paraterminalis [TA]).
