Exploration of the brain from its lateral aspect
Inferior and posterior horns of lateral ventricle
The tapetum is cut away and the lateral ventricle thus opened. Most of the inferior horn is exposed, the entire posterior horn is visible and the area of confluence of these two horns with the central part of the ventricle is shown. This area is known as the atrium. Note the presence of choroid plexus only in the body and inferior horn of the ventricle. Its line of attachment (and thus closure of the ventricle from the transverse fissure medially) is along the concave medial margin of the ventricle.
