Diagonal band of Broca
Lua error in Module:Infobox at line 235: malformed pattern (missing ']'). 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.[1]
Contents
Structure
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.
Nucleus
The nucleus of diagonal band is a structure in the brain. It projects to the hippocampal formation through the fornix.[1]
Function
Along with the septum pellucidum and medial septal nucleus, the diagonal band of Broca is believed to be involved in the generation of theta waves in the hippocampus.[2]
Its behavior can be altered by nerve growth factor.[3]
