Scope Note
Physiological integration of multiple SYNAPTIC POTENTIAL signals to reach the threshold and initiate postsynaptic ACTION POTENTIALS. In spatial summation stimulations from additional synaptic junctions are recruited to generate s response. In temporal summation succeeding stimuli signals are summed up to reach the threshold. The postsynaptic potentials can be either excitatory or inhibitory (EPSP or IPSP).
