Assume that a hypothetical neuron has three presynaptic inputs converging upon it. Presynaptic inputs A and B are excitatory, and C is inhibitory. Indicate which of the following changes will take place by writing the appropriate letter in the blank using the answer code below:
-What would occur if presynaptic neuron B is fired rapidly?
A)There will be no change in potential of the postsynaptic cell.
B)Spatial summation will occur.
C)Temporal summation will occur.

Temporal summation occurs when a single presynaptic neuron fires rapidly, causing the postsynaptic neuron to reach the threshold for an action potential due to the cumulative effect of the excitatory signals.
