XYZ
For the following questions, assume a hypothetical postsynaptic neuron has three presynaptic inputs: X, Y, and Z. Also assume that presynaptic neurons Y and Z are excitatory.
-Refer to the text.If presynaptic neuron X is stimulated, the postsynaptic cell membrane becomes slightly hyperpolarized.What kind of a synapse is involved between presynaptic neuron X and the postsynaptic neuron

A) excitatory synapse
B) inhibitory synapse
C) either an excitatory or an inhibitory synapse
D) collateral axoaxonic
