Anterior perforated substance

Body
was changed:
The anterior perforated substance, or substantia perforata anterior, is an area in the basal forebrain that plays an important role with regards to blood supply of deep brain grey matter structures.
Gross anatomy
Located inwithin the basal forebrain, the anterior perforated substance is an irregular quadrilaterala rectangular area of grey matter which is positioned posterior to the gyrus rectus and olfactory trigone and anterolateral to the optic tract. It is bounded medially by the optic chiasm and laterally by the lateral olfactory striae.
Blood supply
Blood supply is by the medial and lateral lenticulostriate arteries that arise from the anterior and middle cerebral arteries.
Etymology
It derives its name from the numerous small holes created by branches of the anterior and middle cerebral arteries called the lenticulostriate arteries which travel through this area and supply the internal capsule and structures of the basal ganglia.
