neurotransmitters Flashcards
1
Q
exitatory and inhibitory
A
glutamate is excitatory, increases possibility of action potential
GABA is inhibitory, decreases possibility of an action potential
2
Q
neurotransmitter regulation
A
- receptor (ant)agonist
- inhibitory/enhancement of uptake channels (SSRI)
- inhibition of neurotransmitter synthesis/degradation (MAO)
- direct inhibition/enhancement of ion channels
