Assume That a Hypothetical Neuron Has Three Presynaptic Inputs: a and B

Essay

Assume that a hypothetical neuron has three presynaptic inputs: A and B are excitatory, and C is inhibitory. Indicate which of the following changes will take place.
$\begin{array}{lr}\text { 1. What would occur if both presynaptic }\\\text { neurons } \mathrm{A} \text { and } \mathrm{C} \text { were fired simultaneously? }&\text { temporal summation }\_\_\_\\\text { 2. What would occur if presynaptic neuron } B\\\text { were fired rapidly? }&\text { spatial summation }\_\_\_\\\text { 3. What would occur if both presynaptic }&\text { no change in potential of }\\\text { neurons } \mathrm{A} \text { and } \mathrm{B} \text { were fired simultaneously? }&\text { the postsynaptic cell }\_\_\_\end{array}$
