Neuron X Makes Inhibitory Axon-Axon Synaptic Contact with Neuron Y

Multiple Choice

Neuron X makes inhibitory axon-axon synaptic contact with neuron Y at the synapse of Y and neuron Z. Which will occur when action potentials are stimulated in neuron X?

A) Neuron Y will be inhibited from reaching the threshold to fire an action potential.
B) The release of neurotransmitter by neuron Y will be inhibited.
C) The synapse between neurons Y and Z will be changed from an excitatory synapse to an inhibitory one.
D) Neurons Y and Z will both be more likely to reach threshold and fire an action potential.
E) Neurons Y and Z will both be less likely to reach threshold and fire an action potential.
