26
What part of the cerebral hemisphere is sensory and motor?
Anterior is motor Posterior is sensory
27
What is the medial portion of the cerebral cortex?
storage and retrieval of processed information
28
What does the temporal part of cerebral cortex detect?

Vision
30
What separates the 2 occipital lobes from the cerebellum?
Tentorium cerebelli
31
What separates the right and left cerebral hemispheres?
Falx cerebelli
32
33
Pontomedullary?
Area connecting the pons and midbrain
34
35
A = IV ventricle B = dorsal columns
36
What does the cerebellum receive information from?
1. Pyramidal tracts (motor intention of brain) 2. Ipsilateral proprioceptors from periphery 3. Vestibular nucleii re. balance and posture
37
What does the cerebellum send info to?
Cerebral cortex
38
How does the cerebellum send info to the cerebral cortex?
Via the superior cerebellar peducle
39
In the brain, does grey or white matter sit on the outside?
Grey matter on outside
40
