Bio Basis And Behavior Flashcards
Action potential
A neural impulse ; a brief electrical charge that travels down an axon
Threshold
The level of simulation required to trigger a neural impulse
Refractory period
In neural processing, a brief pause occurs after a neuron fires
Acetylcholine (2) what does it work wi6
Enables muscle action
Learning & memory
Works with Glumate
When a person has Alzemiers disease, what neurotransmitting neurons detriorate?
Acetylcholine (ACh) producing neurons
Dopamine
Influence movement , learning, attention, & emotion
What happens if dopamine is over/ under supplied?
Oversupply -linked to schizophrenia
Undersupply- linked to temors &decreased mobility in Parkinson disease
Serotonin
Affects mood, hunger sleep &arousal
What is linked to undersupplied levels of serotonin
Depression
Norepinephrine/noreadrillin
Helps control alertness & arousal
Uppersupply of norepinephrine
Undersupply can depress mood.
Gaba
A major inhibitory neurotransmitter
Undersupply of gaba
Undersupply linked to seizures, tremors, and insomnia
Glutamate
A major excitatory
neurotransmitter;
involved in memory
Oversupply of glutamate
Oversupply can overstimulale the brain producing migraines or sezures (which is
why some people avoid MSG, moresodium
glutamate in food)
