The membrane potential of an unmyelinated neuron changes during the transmission of an idealized neural impulse. ... Neurons allow the brain to communicate with the rest of the body through the propagation of waves of depolarization, known as action potentials, ... In the declining phase of the action potential,

During depolarization, the neuron cannot react to additional stimuli and this inability is termed the absolute refractory period. Also during depolarization, the RMP of −70mv is reestablished. When the RMP becomes more negative than usual, this phase is termed hyperpolarization.

As stated earlier action potentials are self generating once threshold is reached. As sodium ions rush in during the depolarizing phase of the action potential a large concentration of sodium ions accumulates in that region of the axon. ... The neuron communicates by nerve impulses, also known as action potentials.

Depolarization Phase of the Action Potential The initial portion of the action potential where the voltage sweeps from the resting potential past the neutral voltage to where the inside of the axon is now positive relative to the outside of the axon. ... Soma The part of the neuron where the nucleus is found.

The first step in sending a signal (Action ; Potential) is called DEPOLARIZATION. ... The graph above shows the inside of the neuron becoming more positive and less positive during the complete action potential. Observe how this relates to the movement of Na; + and K; + ions across the membrane.
