Inferior view of the temporal horn of the lateral ventricle and choroidal fissure. Note here the location of the temporal horn of the lateral ventricle deep to the parahippocampal gyrus. The uncus is immediately medial. The curvilinear fimbria of the fornix courses just lateral to the thalamic pulvinar and lateral geniculate body, and along the medial edge of the temporal horn adjacent to the choroidal fissure. The tenia of the fornix is the name for the attachment site of the tela choroidea within the temporal horn to the lateral surface of the fornix. (Image courtesy of AL Rhoton, Jr.)
