Quizplus · Accepted Answer

Spatial summation refers to the process in which the postsynaptic neuron integrates multiple synaptic inputs from different presynaptic neurons at different sites. This can happen when the inputs arrive simultaneously or close in time, and the resulting summation of their effects can trigger the neuron to fire an action potential. Saltatory conduction refers to the propagation of action potentials along a myelinated axon, while the absolute refractory period is the time during which a neuron cannot generate another action potential. Temporal summation involves the integration of multiple inputs from the same presynaptic neuron over time, which can lead to firing if the inputs are frequent enough and strong enough.
