A) A stronger action potential results.
B) A weaker action potential results.
C) No action potential results.
D) Many action potentials result.

Question

Quizplus · Accepted Answer

When twice as many inhibitory postsynaptic potentials (IPSPs) as excitatory postsynaptic potentials (EPSPs) arrive in close proximity at a postsynaptic neuron, it will result in an overall hyperpolarization of the cell membrane, making it less likely for an action potential to occur. Therefore, no action potential will result.
