Frage 1
Frage
If a drug speeds up the reuptake of a neurotransmitter, it's an
Antworten
-
antagonist
-
agonist
Frage 2
Frage
If a drug disrupts the production of a neurotransmitter, it's an
Antworten
-
agonist
-
antagonist
Frage 3
Frage
What effect on APs would a glutamate agonist have?
Antworten
-
More action potentials (an increase in excitability)
-
Less action potentials (a decrease in excitability)
Frage 4
Frage
What effect on APs would a GABA agonist have?
Antworten
-
More action potentials (an increase in excitability)
-
Less action potentials (a decrease in excitability)
-
Neither, because GABA doesn't influence excitability
