When a neuron is not conducting any impulse, i.e., resting, the axonal membrane is comparatively more permeable to potassium ions ( ) and nearly impermeable to sodium ions ( ). Similarly, the membrane is impermeable to negatively charged proteins present in the axoplasm. Consequently, the axoplasm inside the axon contains high concentration of and negatively charged proteins and low concentration of . In contrast, the fluid outside the axon contains a low concentration of , a high concentration of and thus form a concentration gradient
