What happens when a stimulus is applied to a resting polarized membrane of a neuron?
1
The membrane becomes more permeable to potassium (K+), resulting in depolarization.
2
The membrane becomes more permeable to sodium (Na+), leading to depolarization.
3
The membrane becomes impermeable to both sodium and potassium ions.
4
The resting potential is maintained, and no action potential is generated.
