Shit that fuckin matters kinda maybe not really who the fuck knows Flashcards
learn the fuckin parts of the brain and how to label them
lobes and major structures (ex primary motor cortex, frontal lobe)
independent variables
variable that is manipulated by the experimented
dependent variables
a variable that is measured by the experimenter
operational definitions
detailed defintion of a variable
internal v external validity
int: did the independent variable cause the conclusion? was the study done right
ext: can the conclusion be generalized
case study v experiment
case study is some random shit that happened in nature so you might as well… but you cant fully make conclusions from it
experiment is planned out and designed
Why the fuck is there a resting membrane potential?
1.sodium potassium pump. Kicks 3 Na+ ions out for every 2K+ ions that come in\
- Leaky K+ channels so that shit gets out
- 70 mV is sweet spot
depolarization
making the -70 closer to 0
acetyocholine does this by adding sodium ions
hyperpolarization
GABA receptor shit does that by adding chloride
making it more negative
agonist
drug that mimics or potentiates the action of an endogenous neurotransmitter
it can de or hyper polarize depending on original use
GABA hyper
acetylcholine
what the fuck do depolarizing and hyperpolarizing really do?
hyperpolarizing increases likelihood of action potential
depolarizing decreases
reward pathway
ventral tegmental area (midbrain) sends axons up to nucleus accumbens (forebrain) w
motor movements happen everywhere
primary motor cortex
substantia nigra
basal ganglia
more?
jajaja
PET v fMRI v MRI/CT
PET are neurotransmitter specific systems
fMRI is bloodflow and neural activity… not which neurons are which
MRI/CT are pictures, not brain in action
dorsal and ventral streams
ventral is lower.. detects what object is (if harmed, agnosia/progro…)
dorsal is upper stream
where object is in space (if harmed, motion blindness)
