AP Psychology Unit
epigenetics - particular genes that get turned on or off from the environment
dna makes chromosomes, they’re in the nucleus.
2 questions on genetics.
central
-brain and spinal cord
peripheral nervous system
-anything u can control
voluntary = somatic
autonomic nervous system
involuntary
sympathetic nervous system - under times of stress, scared or nervous.
fight or flight
in teased heart rate, nerves, etc
digestion slows
rest and digest
normal breathing
normal seeing/vision
under normal conditions
action potential
action where neuron is active
positive charge
res to g state
waiting for neurotransmitter to fire
after fire you wait
neuron has the potential to fire
polarization
depolarization - inside and outside the same charges + and +
refractory period - cannot work and fire
between cell - chemical
down a cell - electrical
acetylcholine- lower levels = alzheimer’s and myo
dopamine- reward system and movement too high = causes hallucinations in schizophrenia too low = parkinson’s
serotonin- associated with mood under supply = depression. prozacs
adrenaline / norepinephrine
haha - se jura n insomnia with central nervous system not stopping m
glutamate - pedal
painkillers lower pain
substance p - pain
oxytocin- forget pain ml
endorphins elevate mood eu. era high
Barbitioud - depressant.
physical and psychological withdrawal different
psychology = i can’t accomplish this without drug
physical = hurts to do it
alcohol affects GABA
what’s makes something polar = opposite
inside is really negst to d and outside is positive
chemicals bond to the dendrite
ion exchange
cell gets grsddañy less negative
everything becomes semi persbñd ions become easy to go in
outside and inside positive is depolarization
signal goes down cell neurotransmitter gets down the cell
sodium will go out negative again in refractory period waits for a more bonds
REFRACTORY = NOT SIGNALS/ HITTING
Polarized - the electrical charge on the outside of the membrane is positive while the electrical charge in the inside of the membrane is negative.
Action potential - inside ions move outside, outside ions move inside.
Stimulus - neurotransmitter from another neuron
Polarization - membrane is negative inside, positive outside.
Depolarization - membrane is positive inside, negative outside.
Threshold level - the point at which there’s no holding back.
Above threshold level, more Na+ goes into the cell, complete depolarization and action potential is created.
Hyper polarization - more inside ions outside than outside ions inside
