Exam 2: Brain and Behaviour

A neuron's axon has just fired and released chemicals into the synapse. The action potential drops below its resting level and is therefore less able to fire. Other neurons in the area are asking for more chemicals, but it replies, "I can't right now, I have to take a break." What do we call this "break"?
