ANSWER:Step 1 of 2
Temporal summation is a fundamental concept in neurobiology that refers to the process where consecutive impulses, or action potentials, arriving at a neuron within a brief time are added together or 'summed'. This occurs when one presynaptic neuron releases neurotransmitters onto a postsynaptic neuron in quick succession.
The presynaptic neurons of high-frequency action potential generate action potentials of postsynaptic neurons in closed successions. The process of integration of these generated postsynaptic neurons over time is called temporal summation.
