Anatomy 3
Corpus callosum
center of the cerebrum
white matter bundle
bridge between the two hemispheres
surrounded by cingulate gyrus: important for emotion
Diencephalon
region around the thalamus and the hypothalamus
Inferior to the fornix(major output tract of the hipocampus, for memory recall)
and lateral Ventricle
ANterior commissure
above hypothalamus,
white matter tract connecting the two hemispheres for communication
Thalamus
best known for relay and prcessing location for sensory and motor
systems
Hypothalamus
controls stress
fight or flight
reproduction, sleep, thirst, hunger, & homeostatic functions
Mamillary bodies
posterior part of the hypothalamus
memory
Anatomy 3 1
, Optic nerves from retina cross optic chiasm → Optic nerve tracts→
diencephalon
Brain stem
tectum and mid brain consist of superior and inferior colliculi
responsible for vision and hearing, respectively
Rectangular formation
Formation of neurons within the brain stem
regulate sleep, consciousness, pain and motor control
4th ventricle lies between brain stem and the cerebellum
Misc. Brain structures
From brain image in the more anterior part of the brain
Amygdala
within the medial temporal lobe
