    Summary
    This summary is machine-generated.

    Research suggests the complex serotonin system, involving 5-hydroxytryptamine (5-HT) receptors, may play a role in epilepsy. New positron emission tomography (PET) ligands aid in studying these receptors and transporters for potential epilepsy insights.
