Question

what ions rush into a neuron during depolarization? chloride sodium potassium water

Explanation:

Depolarization of a neuron occurs when voltage-gated sodium channels open, allowing positively charged sodium ions to rapidly flow into the neuron, which makes the membrane potential more positive. Chloride ions typically move in during hyperpolarization, potassium ions flow out during repolarization, and water does not drive depolarization.

Answer:

Sodium
