summation

in physiology, the additive effect of several electrical impulses on a neuromuscular junction, the junction between a nerve cell and a muscle cell. Individually the stimuli cannot evoke a response, but collectively they can generate a response. Successive stimuli on one nerve are called temporal summation; the addition of simultaneous stimuli from several conducting fibres is called spatial summation.
