Unit 3: Neuroscience Approach
Human brain
Cerebrum; controls all conscious thoughts, experiences, and actions
Cerebral cortex; surface of cerebrum
temporal lobe
occipital lobe
frontal lobe
parietal lobe
Cerebral hemispheres; joined by corpus callosum
contralateral function
Cerebellum; it controls posture and balance
Brain stem; it controls processes basic for survival
The Nervous System
2 parts
Peripheral nervous system
Central nervous system
Neurons
dendrites; receive inputs and carry them to the cell soma
axon; transmit signals
neurotransmitter; chemical signals released across the synapse so that neurons can communicate with each other
synapse; small gap separating 2 neurons-contact point
