|Brain: Diagonal band of Broca|
Base of brain. (Diagonal band of Broca not labeled, but anterior perforated substance labeled at center.)
Human brainstem, anterior view. (Diagonal band of Broca not labeled, but anterior perforated substance is #5.)
The diagonal band of Broca is one of the forebrain nuclei that are derived from the ventral telencephalon during development. This structure forms the medial margin of the anterior perforated substance.
It consists of fibers that are said to arise in the parolfactory area, the gyrus subcallosus and the anterior perforated substance, and course backward in the longitudinal striae to the dentate gyrus and the hippocampal region.
This is a cholinergic bundle of nerve fibers posterior to the anterior perforated substance. It interconnects the paraterminal gyrus in the septal area with the hippocampus and lateral olfactory area.
