Neuron Electrical Activity
Graph of the Change in Millivolts during the Event

While the neuron is resting, it’s the resting potential that tells all the activities that take place in it. Once the neuron sends information via the axon away from the cell body, action potential now takes place. Therefore, it’s the depolarizing current that creates an explosion of neuron electrical activity that leads to an action potential. Also, it’s the event that forces the resting potential to move from its position towards 0 mV. The threshold is reached when depolarization reaches -55 mV and hence firing an action potential. The threshold is a most important level since no action potential can happen without it. An action potential is achieved when different ions enter the membrane of the neuron. Sodium ions open first and hence circulating both to the inside and outside. Later, potassium ions open and moves to the outside which ends up reversing depolarization. As a result, action potential starts going back to -70 mV by a process known as repolarization. Action potential even goes further below -70 mV since potassium ions stay longer while open; refractory period. Afterward, it goes back to its resting state.
Resting MP neuron electrical activity is associated with differences in individual’s effective style in healthy children, infants, adults as well as some clinical population when signs and symptoms are in remission or reduced. Resting potential al activity mainly …
