How Temporal Summation Can Be Observed?

Temporal summation can be illustrated by firing action potentials in a presynaptic neuron and monitoring the resultant EPSPs

EPSPs
The EPSP responses are a manifestation of synaptic activation (depolarization) in the CA1 pyramidal neurons. For measuring field (i.e., extracellularly recorded) EPSPs, the parameter typically measured is the initial slope of the EPSP waveform (see Fig. 5).
.

How is temporal summation measured?

Temporal summation is a phenomenon in which repeated and equal-intensity noxious stimuli at a specific frequency cause an increase in the pain experienced. Results are usually obtained by comparing pain ratings of the first to the last equal intensity stimulus.

What happens temporal summation?

Temporal summation occurs when a high frequency of action potentials in the presynaptic neuron elicits postsynaptic potentials that summate with each other. ... This allows the membrane potential to reach the threshold to generate an action potential.
