After depolarization, the neuron undergoes repolarization, during which the cell's membrane potential returns to resting state. This is followed by hyperpolarization, where the membrane potential briefly becomes more negative than the resting state, before returning to its baseline. Finally, the neuron enters a refractory period, during which it is temporarily unable to generate another action potential.
A neuron that is not sending a nervous impulse is typically referred to as a resting neuron. In its resting state, the neuron is polarized with a negative internal charge.
The chief positive intracellular ion in a resting neuron is a potassium ion. Just inside the cell of a resting neuron, the membrane is negative.

Resting potential.
The state of a neuron when it is not firing a neural impulse is called the resting potential. This is when the neuron is negatively charged inside compared to outside, waiting for a stimulus to change its electrical charge and initiate an action potential.
If it's approximately -70 mV, then it's in a resting state.

The chief positive intracellular ion in a resting neuron is potassium (K+). At rest, the neuron has a higher concentration of K+ inside its cell membrane compared to outside. This creates a negative membrane potential, which is crucial for maintaining the resting state of the neuron.
exhibit a resting potential that is more negative than the "threshold" potential.
An unstimulated neuron is a nerve cell that is not currently transmitting signals. It is in a resting state, with a stable membrane potential, and is not actively firing action potentials or sending messages to other neurons.
