After the action potential peaks, the Na+ channels close, and no more Na+ can enter the cell. This phenomenon is called: Neuronal spike Refractory period Inhibitory postsynaptic potential (IPSP) Resting potential

Right after an action potential, a neuron is unable to produce another action potential, because its sodium channels are temporarily inactivated. This is referred to as: spatial summation the absolute refractory period inhibitory post-synaptic potential the relative refractory period
Jhankar T.
During the late absolute refractory period of an action potential, the voltage-gated Na+ channels are closed and cells are hyper-excitable. In the relative refractory period, the voltage-gated K+ channels are active and cells are more excitable. Only smaller action potentials are achievable. Most voltage-gated Na+ channels have reset and cells are not excitable. Most voltage-gated Na+ channels are inactivated and cells are not excitable.
Mystique T.
Which of the following occurs during the refractory period of a neuron? The neuron cannot generate an action potential. Sodium channels open, releasing sodium ions into the neuron; potassium channels close. Potassium channels open, releasing potassium ions from the neuron; sodium channels close. A nerve impulse is propagated. Sodium and potassium channels open.
