What do we call the state of a neuron when it is not firing a nural impulse?

The state of a neuron when it is not firing a neural impulse is called the resting potential. During this phase, the neuron is polarized, with a negative charge inside relative to the outside, primarily due to the distribution of ions such as sodium and potassium. This resting state is essential for the neuron to be ready to respond to stimuli and generate an action potential when activated.
