Answer to Question 1

A
The most important understanding of how the brain functions is that each neuron continually receives thousands of competing inputs. Some inputs are excitatory; others are inhibitory. When the input is excitatory, it responds with an action potential. On the other hand, when the input is inhibitory, there is no response.
