Indicate an antiseizure drug, which has an impotent effect on the T-type calcium channels in thalamic neurons?

Correct Answer: C

Rationale: Ethosuximide is known for its potent effect on T-type calcium channels in thalamic neurons, which is its primary mechanism for treating absence seizures. However, the question uses 'impotent,' likely a typo for 'important' or 'potent.'
