Both temporal and spatial summation allow for grading of nervous response If the stimulation affects too few presynaptic neurons or the frequency of stimulation is too low the cell does not reach threshold and no action potential is generated Differentiate between the two by matching the description with the correct summation type Several inputs from different presynaptic cells create EPSPs that sum together to bring the neuron over the threshold for an action potential Several inputs from the same presynaptic cell arrive in rapid succession summing into a larger depolarization that brings the neuron over the threshold for an action potential Spatial summation Temporal summation
