Document Summary

The biology of the mind: (cid:498)everything psychological is simultaneously biological(cid:499) Endocrine system (mod 5) (cid:498)old(cid:499) brain structures (cid:523)mod (cid:888)(cid:524) (cid:498)new(cid:499) brain structure (cid:523)mod (cid:889)(cid:524: cerebral cortex, divided brain. How can we study the brain (mod 6) Nerves connecting cns to muscles and organs. Sensory neurons: input from body to cns (sense bug on hand) Motor neurons: output from cns to control muscle movements (swat bug off hand) Interneurons: sensory-motr relay within cns, both voluntary and reflex (involuntary) movement, spinal reflex arc. Different levels wired to different body parts: quadriplegic vs. paraplegic. Sensory messages are directed to higher centers (except olfaction) Sensory relay or gateway or (cid:498)traffic officer(cid:499) (cid:498)little brain(cid:499) traditionally thought to help you (cid:498)walk and chew gum at the same time . Scientists now realize it"s much more diverse abd sophisticated involved in balance and muscle coordination higher cognitive tasks. Parkinsons disease affects the basal ganglia: tremor, rigidity, problems initating movement.
