The objective of this study was to interrogate the anticonvulsant potential of Δ9-THCA in various seizure models—the Scn1a+/− mouse model of Dravet syndrome, the 6-Hz model of psychomotor seizures and the maximal electroshock (MES) model of generalized tonic-clonic seizures. The gene discussed is SCN1A; the disease is Dravet syndrome.
