"WebAn action potential is a transient change in electrical potential on the membrane surface of a neuron or effector cell. This momentary change occurs when the cell is stimulated, resulting in the transmission of an electrical (nerve) impulse through some part of the nervous system.

WebFor instance, we know for a fact that readiness potential occur when the movement is voluntary, so when you do a movement that is not voluntary, allegedly you won't have any readiness potential (or at least it would be lower than a voluntary one). I have worked on it, this is a very interesting subject. I hope I have helped you a little bit. WebFeb 8, 2024 · Voluntary movements are usually preceded by a slow, negative-going brain signal over motor areas, the so-called readiness potential (RP).
