This is an example of temporal summation, as the IPSPs are arriving rapidly in sequence from a single presynaptic location, adding up over time to prevent an action potential. Spatial summation involves multiple presynaptic locations and IPSPs arriving at the same time. Tetanus refers to a sustained contraction of a muscle due to rapid stimulation, unrelated to synaptic integration. The refractory state is a period after an action potential where the neuron is temporarily unable to fire again. An action potential with an abnormally high peak of depolarization would not be caused by IPSPs.
