Local hyperpolarization in a synapse is called a/an ________.
A) excitatory postsynaptic potential
B) resting membrane potential
C) inhibitory postsynaptic potential
D) gap junction potential
E) action potential
Hyperpolarization
A change in a cell's membrane potential that makes it more negative, moving further from zero.
Inhibitory Postsynaptic Potential
Hyperpolarization in the postsynaptic membrane, which causes the membrane potential to move away from threshold.

Final Answer :
C
Explanation :
Local hyperpolarization in a synapse is referred to as an inhibitory postsynaptic potential (IPSP). This occurs when the postsynaptic membrane becomes more negatively charged than usual, making it less likely for an action potential to be generated.
