Physiology Flashcards
Franz Gall
phrenology
Pierre Flourens
early studies using extirpation (ablation)
William James
functionalism: styling how mental processes help individuals adapt to their environment
John Dewey
Functionalism
Criticized the idea of a reflexive arc
Hermann von Helmholtz
measured speed of a nerve impulse
Sir Charles Sherrington
inferred the idea of a synapse
Lateral hypothalamus
LH = lacking hunger
hunger center, detects when your body needs food
aphagia
disruption of lateral hypothalamus causes one to not want to eat
vetromedial hypothalamus
VH = very hungry
satiety center, tells body when you’ve had enough to eat
hyperphagia
excessive eating
anterior hypothalamus
sexual behavior
extrapyramidal motor system
gather info about body position and sends info to brain
septum
primary pleasure center inhibits aggression (can result in septal rage if it is damaged)
James Olds & Peter Milner
discovered that rats will self-stimulate the septum
Hendrick Kluver & Paul Bucy
linked amygdala with defensive/aggressive behavior
Kluver-Bucy syndrome
bilateral removal of amygdala
association area
combines input from many brain regions (i.e. prefrontal cortex)
projection area
receive incoming sensory info or send out motor-impulse commands (i.e. visual cortex)
parietal lobe
somatosensory cortex
Hubel & Wiesel
physiology of visual perception
which lobe is the auditory cortex in?
temporal lobe
Sperry & Gazzaniga
studied epileptic patients and found that the ones who had severed corpus callosum did not have inter-hemispheric communication
resting position has a slight ____ charge
negative
graded potential
postsynaptic potentials in dendrites vary depending on intensity based on how much the receptor is stimulated
acetylcholine is associated with which disorder?
alzheimer’s
epinephrine (adrenaline) is associates with which behavior?
fight or flight response
acetylcholine is associated with which behavior?
voluntary muscle control
