-
resting potential
is cell negative or positive? - nueron is stable *negative charge when cell is inactive
- action portential
- voltage spike that travels along axon
- absolute refractory period
- brief time after action potential before another potential can begin
- nuerotransmitter
- sends messages between nuerons--chemical
-
presynaptic neuron
postsynaptic neuron
receptor sites
lock and key model -
SENDS
RECIEVES
part of the dendrite where nuerotrans. is recieved
only ONE transmitter will affect a receptor - nueral networks
- interconnected nueral cells, can learn.
-
cerebral cortex
motor
sensory -
MOTOR-left side
SENSORY-right side - Hindbrain
- cerebellum, "little" VOLUNTARY movement and balance..coordination
- cerebrum
- complex mental activities..learning/thinking
- 4 lobes?
- frontal, parietal,temporal, and occipital
- 5 LANGUAGE centers
- motor cortex-word pronounced, angular gyrus-puts visual and audio together, visual cortex, wernickes area-auditory, brocas area-speech
-
thalamus
but not what? - relays messages, distributes sensory sensations NOT SMELL
-
hysothalamus
4 fs? - below thalamus, POWER, maintanence activities, endocrine.. emotion!feeding, fithing, fleeing, fucking
-
limbic system
hippocampus -
emotions and memory
memory and learning -
Endocrine system
pituitary -
bodys chemical commun. system, set of glands that secrete hormones into blood stream.
hormones -
somatic nervous system
afferent
efferent -
same!
incomongin
outgoing -
autonomic nervous
sympathetic
parasympathetic -
arouses! mobilizes bodys resources
calms!conserves bodys resources
homeostasis - EEG
- records activity, electrodes placed on scalp
- cat scan
- 3-D xrays
- fmri
- shows visual cortex activated as subject looks at faces
- lesioning
- tissue destruction, naturally or experi. cause destruction of brain tissue
- CORPUS CALLOSOM
- the information highway to each brain half
-
split brain
what does it help? - 2 hemispheres are isolated, cut fibers of CC--helps epilipsey
- cerebral cortex
- thoughts, emotion, voluntary emotions
- spinal
- involentary nueral fibers
- medulla
- heart and breathign
- reticular from
- arousal
- hippo
- learning
- thalamus
- swith board
- hypo
- 4 fs "power"
