spike amplitude from trough

Common definition: Voltage indicating height of action potential, calculated as the difference between AP peak and AHP trough voltages. Commonly measured using first AP in train at rheobase current.

Electrophysiological values of spike amplitude from trough across neuron types from literature:

    Normalization criteria:
  • Values are unchanged from those reported. Refer to individual articles for definition and calculation methodology.
