generator potential

gen·er·a·tor po·ten·tial

local depolarization of the membrane potential at the end of a sensory neuron in graded response to the strength of a stimulus applied to the associated receptor organ, for example, a pacinian corpuscle; if the generator potential becomes large enough (because the stimulus is at least of threshold strength), it causes excitation at the nearest node of Ranvier and a propagated action potential.

generator potential

the nonconducted electrical charge that is developed when the sensitive part of a RECEPTOR is stimulated. The magnitude of the potential depends on the intensity of the stimulus, and when it reaches a certain threshold it may give rise to an ACTION POTENTIAL.

The generator potential appeared as a short-latency downward deflection of the voltage trace, and the amplitude of the evoked response increased with increasing flash intensity.
Previously we have shown that extracellular, light-induced generator potentials in the epistellar bodies of Eledone cirrhosa can be produced by light flashes of different intensity and duration, transmitted through the mantle sac wall of the octopus (Cobb et al.
Resting potential was recorded during cell impalement and generator potentials were recorded in response to light flashes, before switching to current injection in these experiments.
As already seen for the extracellular compound generator potentials, the time-to-peak depolarization for individual photoreceptor cells decreased with increasing stimulus intensity [ILLUSTRATION FOR FIGURE 10C OMITTED].
While perfusing the slice with modified Limulus Ringer (first trace), the light flash evoked a burst of [approximately]7 action potentials at the leading edge of the generator potential, followed by 34 action potentials yielding a steady-state firing rate of [approximately]4.
0 to 0 impulses/s, was associated with a partial hyperpolarization of the generator potential from 10 to 5 mV depolarization.
He covers cellular processes, cell membranes, channels and control of membrane potential, sensory generator potentials, action potentials, synapses and muscles, and includes a practice examination with answers.
