Planarian as an Animal Model for Experimental Acute Seizure

Seizures negatively impact various functions and life quality. Planaria worms were exposed to varying concentrations of chemoconvulsants to evaluate their seizure phenotypes and disruptive motility. This study proposes using planaria worms as a model for acute seizures in humans and holds significance in drug development for...

Pupillary Response as Assessment of Effective Seizure Induction by Electroconvulsive Therapy

Pupillary responses (light reflex) were measured for assessment of adequate seizure induction by electroconvulsive therapy using an automated infrared pupillometer immediately after electrical stimulation. Constriction ratio was calculated and compared with seizure...

Electroconvulsive Seizures in Rats and Fractionation of Their Hippocampi to Examine Seizure-induced Changes in Postsynaptic Density Proteins09:07

Electroconvulsive Seizures in Rats and Fractionation of Their Hippocampi to Examine Seizure-induced Changes in Postsynaptic Density Proteins

Electroconvulsive seizure (ECS) is an experimental animal model of electroconvulsive therapy for severe depression. ECS globally stimulates activity in the hippocampus, leading to synaptogenesis and synaptic plasticity. Here, we describe methods for ECS induction in rats and for subcellular fractionation of their hippocampi to examine seizure-induced changes in synaptic...
