Preguntas del test (35)
1If a drug speeds up the reuptake of a neurotransmitter, it's an
- Aantagonist
- Bagonist
2If a drug disrupts the production of a neurotransmitter, it's an
- Aagonist
- Bantagonist
3What effect on APs would a glutamate agonist have?
- AMore action potentials (an increase in excitability)
- BLess action potentials (a decrease in excitability)
4What effect on APs would a GABA agonist have?
- AMore action potentials (an increase in excitability)
- BLess action potentials (a decrease in excitability)
- CNeither, because GABA doesn't influence excitability
