Above the Midbrain
Superior: Dorsal up top when standing Anterior front : Rostral Posterior: Caudal
Inferior: Ventral
Below the midbrain: shift once clockwise
This is because when we stand up the back of the head becomes dorsal
Below the Midbrain
Superior: Rostral
Anterior: Ventral Posterior: Dorsal
Inferior: Caudal

What is a gyri?
Single is sulcus
Those are the crevices lines in between all the brain fold
Single is gyrous
Those are the actual folds

- Orange is Parietal lobe: Sensory input, pain, touch, temperature
- Pink is Occipital lobe: Vission
- Green is Temporal lobe: Hearing, speech comprehension
