Question

Quizplus · Accepted Answer

The effect on the postsynaptic membrane potential when an excitatory synapse and an inhibitory synapse are activated simultaneously is impossible to predict without knowing the relative strength and timing of these synapses. The net effect could be depolarization, hyperpolarization, or no change, depending on the specifics of the synaptic inputs.
