Several types of fly mutants with epileptic phenotypes are currently used in modeling seizures. The so-called "bang-sensitive" mutants exhibit seizures and paralysis upon mechanical stimuli; seizures can be suppressed by the administration of anticonvulsant drugs. Seizure-suppressor mutants include Sh, shakB and para.
Fly stocks in the Bloomington collection that can be used to study seizure disorders and epilepsy are listed here (see also the page for Galphao-related epilepsies).
