Front Back
Sulcus (pl. Sulci)
Fissure in the brain. Between Gyri
Gyrus (pl. Gyri)
A ridge on the cerebral cortex, Generally surrounded by one or more sulci.
Longitudinal Fissure
Separates the two hemispheres of the brain.
Transverse Fissure
Separates the Cerebrum from Cerebellum
Cerebral Cortex
Motor - Frontal
Sensory - Parietal
Corpus Callosum
Bundle of neural fibers beneath the cortex at the longitudinal fissure. Connects right and left cerebral hemispheres
Fornix
C-Shaped bundle of neural fibers below the Corpus Callosum that carries signals from the hippocampus to the mammillary bodies and septal nuclei
Central Sulcus
Separates the frontal lobe from the parietal lobe (primary motor cortex from primary sensory cortex)
Precentral Gyrus
Primary motor cortex location
Postcentral Gyrus
Primary sensory cortex location
Lateral Sulcus
Divides Frontal and Parietal Lobes from Temporal Lobe below.
Diencephalon
"interbrain" - located near the midline of the brain, above the mesencephalon.
Thalamus
Between cerebral cortex and midbrain.  Relays sensation, spatial sense, regulation of consciousness, sleep, alertness.
Intermediate Mass
Middle of Thalamus
Hypothalamus
Controls body temperature, hunger, thirst, fatigue, sleep, circadian cycles. Links endocrine system to nervous system via pituitary gland. Inferior and anterior to Thalamus
Mammillary Bodies
Undersurface of brain, posterior to pituitary gland. Involved in recognition memory.
Pineal Gland
produces melatonin, modulation of wake/sleep patterns and seasonal functions.
Cerebellum
- Cerebellar Hemispheres
- Vermis
- Arbor Vitae
- Folia
Brain Stem
Midbrain
- corpora quadrigemina


1) superior colliculus
2) inferior colliculus

Pons
medulla oblongata: deals with autonomic, involuntary functions (breathing, heart rate etc)
-pyramids
Ventricles
- Lateral (interventricular foramen)
septum pellucidum

-Third
-Cerebral Aqueduct
-Fourth
