Human Body & Health

During an epileptic seizure, inhibitory GABAergic neurons are overwhelmed, leading to excessive action potential firing in the brain. Which effect is most likely?

A)Reduced resting membrane potential
B)Increased glutamate release
C)Decreased neuronal chloride influx
D)Enhanced reuptake of dopamine

💡 Explanation

Increased action potential firing leads to more frequent depolarization of presynaptic terminals, which then causes increased calcium influx and subsequent glutamate release. Therefore, the correct answer is increased glutamate release rather than reduced resting membrane potential because this results from GABA agonists, which are overwhelmed during seizure activity.
