Researchers Find That Repeated Stimulation of Hippocampal Neurons Involved in Memory

question 99

Multiple Choice

Researchers find that repeated stimulation of hippocampal neurons involved in memory and learning leads to potentiation of synaptic transmission.  Patch-clamp recordings of stimulated neurons are shown below (dotted line: baseline; solid line: after repeated stimulation [potentiated]) . Which of the following neurotransmitter receptors on the postsynaptic membrane is most likely involved in this process?

• A)Dopamine D₂ receptor
• B)GABA-B receptor
• C)Glutamate NMDA receptor
• D)Glycine receptor
• E)Norepinephrine alpha-2 receptor
