Electroshock Induced Seizures in Adult .

The nematode is a useful model organism for dissecting molecular mechanisms of neurological diseases. While hermaphrodite contains only 302 neurons, the conserved homologous neurotransmitters, simpler neuronal circuitry, and fully mapped connectome make it an appealing model system for neurological research. Here we developed an assay to induce an electroconvulsive seizure in which can be used as a behavioral method of analyzing potential anti-epileptic therapeutics and novel genes involved in seizure susceptibility. In this assay, worms are suspended in an aqueous solution as current is passed through the liquid. At the onset of the shock, worms will briefly paralyze and twitch, and shortly after regain normal sinusoidal locomotion. The time to locomotor recovery is used as a metric of recovery from a seizure which can be reduced or extended by incorporating drugs that alter neuronal and muscular excitability.
