Temporal summation physiology Britannica

Web2 Sep 2016 · Temporal summation occurs when a burst of action potentials reaches a nerve fiber terminal. If the terminal is excitatory, the first action potential in the burst produces a depolarizing EPSP in the motor neuron that begins to decay toward the resting potential. Before the decay is complete, another action potential arrives in the terminal and ... Web6 Jan 2010 · Summation.

WebSummation is the adding together of these impulses at the axon hillock. If the neuron only gets excitatory impulses, it will generate an action potential. If instead the neuron gets as many inhibitory as excitatory impulses, the inhibition cancels out the excitation and the nerve impulse will stop there.
