ANATOMY
OF THE MEDIAL (MIDSAGITTAL) SURFACE OF THE BRAIN, WITH
BRAIN STEM REMOVED
When the brain stem is
removed, a midsagittal view reveals the C-shaped course of the fornix, extending
from the hip-pocampal formation in the temporal lobe to the septum and hypothalamus.
Temporal lobe structures, such as the parahippocampal cortex, the dentate gyrus
and fimbria of the hippocampus, and the uncus (olfactory cortex) also are
visible. In the hypothalamus, the caudal mammillary bodies and the
interconnecting pathway to the thalamus, the mammillothalamic tract, are
revealed.
