    A post synaptic neuron must sum or integrate all of the incoming signals. This process of integration is called "summation." The greater the depolarizing summation, the greater the chance that a nerve impulse will be initiated.

    There are two types of summation: spatial summation and temporal summation.

    Spatial summation results from the buildup of ...
