The thalamus (Greek, chamber)
lies on the midline between the
cerebral cortex and the midbrain
(mesencephalon). Its two halves
surround the third ventricle.
There are two hippocampi
(Greek: seahorse) and two
amygdalae (Greek: almond,
tonsil).
The fornix (Latin: arch) connects
the hippocampus to the
mamilliary bodies.

The pituary gland is an
endocrine gland secreting a wide
range of hormones. It lies next to
the hypothalamus (Greek, under
chamber).
The anterior and posterior
commisures connect the left and
right hemispheres.
