Question

Antiseizure medications work by stabilizing the electrical activity in the brain to prevent or control seizures. Delaying an influx of sodium ions (A) and slowing an influx of calcium ions (D) help to stabilize neuronal membranes and reduce the ability of the neurons to fire at high frequencies, which is a common mechanism of many antiseizure drugs. Stimulating an influx of chloride ions (B) typically increases the action of GABA, a major inhibitory neurotransmitter in the brain, which can help to calm neuronal activity and prevent seizures. Increasing the neuronal firing in the brain (C) would likely provoke seizures rather than prevent them, and reducing an influx of potassium ions (E) is not a recognized mechanism of action for antiseizure medications.
