Common definition: Voltage indicating height of action potential. Usually calculated as the difference between AP peak and AP threshold voltages. Commonly measured using first AP in train at rheobase current.
Electrophysiological values of spike amplitude across neuron types from literature:
Values manually standardized case-by-case to correspond to calculation definition of difference between AP peak and AP threshold. Since authors use different APs for defining spike amplitude (e.g., evoked using rheobase current, via synaptic input, etc.), please refer to individual articles for specific methodology.
