In the depolarization step of action potential where the membrane resting potential is reversed by the rush of sodium ions into a neuron.
A membrane potential shift from -70mV to +30mV for a limited period of time is known as an action potential.
The moving action potential has three stages:
1) The depolarization step, where sodium ions rush into a neuron and reverse the membrane resting potential; and
2) repolarization, which is a mechanism that restores the resting voltage of the membrane and the ionic concentration in the cell, is caused by the closure of the voltage-gated sodium channels and the opening of the potassium channels.
3) Hyperpolarization, when excessive potassium ion efflux occurs as a result of some open potassium channels increasing potassium permeability and causing a drop in the membrane potential.
4) The action potential, which is a transient reversal of membrane potential that travels through the axon, comprises three phases that are described above.

A model organism is a species that has been widely studied to understand a particular biological phenomena, normally used because they are easy to breed and maintain in a laboratory setting and has certain experimental advantage.
The criteria that Thomas hunt Morgan was looking for include; the model organism should be small in size, easy to keep in the laboratory and also able to produce large number of off springs in a short time.
