PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -So, when an axon is at rest, the anions give it a negative charge, the sodium pumps keep sodium out and potassium in, and the sodium gates and potassium gates are all closed. Because of the positive-negative difference between the inside and outside, this resting state is called a resting potential.

Detailed explanation-2: -The resting potential is the resting state of the neuron, during which time the neuron has an overall negative charge. The resting potential in neurons is approximately-70 milliVolts (mV). The negative sign indicates the negative charge inside the cell relative to the outside.

Detailed explanation-3: -The relative excess of positive charges outside and negative charges inside the membrane of a nerve cell at rest is maintained because the lipid bilayer acts as a barrier to the diffusion of ions, and give rise to an electrical potential difference, which ranges from about 60 to 70 mV.

Detailed explanation-4: -Now in the axon, there are more negative charges on the inside than on the outside during the resting potential giving the axon a negative voltage when comparing the inside to the outside (Figure 6). Figure 6. A volt meter measures the voltage difference across the membrane of an axon during a resting potential.
