WebDuring the action potential, the electrical charge across the membrane changes dramatically. This positive spike constitutes the action potential: the electrical signal that typically moves from the cell body down the axon to the axon terminals. The electrical signal moves down the axon like a wave; at each point, some of the sodium ions that ...

WebThe rate law of action potentials indicates that communication within the nervous system occurs via the timing or frequency of discharges and duration of pauses. The duration of hyperpolarization is the limiting factor in the rate at which action potentials can be initiated. WebThe action potential is unidirectional. It will go from the hillock (area where the axon starts) to the terminus (end of the axon near the synapse) in a wave like manner. He was saying that the reason for this is because the membrane is hyper polarized for a while after the action potential has past (more negative then the resting potential).

Dopamine, norepinephrine, serotonin, histamines WebAn action potential has an all-or-nothing property which means that any stimulus producing a lower than threshold potential will potentially result in no response, while a stimulus producing threshold potential will produce a full response in the excitable cell.

WebThe depolarization of the neural axon during an action potential is driven by an influx of sodium ions, entering through voltage-gated sodium channels. Following this stage, voltage-gated potassium channels are stimulated, allowing potassium ions to exit the axon and causing hyperpolarization.
