okay so last class we covered/cleared up a couple things:

1. that the cerebellum makes the body movements NOT JERKY but smoooth, and recieves sensory and motor input
and that the brain stem has 3 MAIN parts to it
1. Midbrain: which is the relay center for the cerebrum, celebellum, and breathing/relfex movements of the head
2. Medulla Oblangotta : which is the autonomic (which is described as occuring involuntary) control center, changing the heart beat outside of the heart
3. Pons (mr.mac had fun saying that word) which is the piece of the connective tissue, the bridge of the white matter at the base of the brain

2. that LEARNING is the ability to retain and apply past memories
and that MEMORY is the ability to hold on to or recall a piece of information
there are 3 types of memory
1. Short term - had the information for a short period of time. ex: phone number you look up
2. Long term (more "hands on") has had the info for a LONG period of time/life (semantic memory)
3. skill memory- a combo of motor activities, like swimming/using scissors

3.Broca and Wernicke's areas are only in the left hemisphere of the brain
BROCA- ability to speak ( broca = blah blah blah)
WERNICKE - ability to comprehend speech/understand it

DURING class we were told the story of the man who dealt with explosives and got that metal rod through his head and still managed to survive. well, his name was PHINEAS GAGE.
