Which electrical event is characteristic of inhibitory synaptic interactions?

AA neurotransmitter agent that selectively opens ligand-gated chloride channels is the basis for an inhibitory postsynaptic potential (Correct Answer)
BBecause the Nernst potential for chloride is about -70 mV, chloride ions tend to move out of the cell along its electrochemical gradient
CA neurotransmitter that selectively opens potassium channels will allow potassium to move into the cell
DAn increase in the extracellular sodium concentration usually leads directly to an inhibitory postsynaptic potential
