It has been known that many C. elegans genes can function similarly to mammalian genes. And its genome is surprisingly similar to that of humans （40%homologous）. So C. elegans becomes an attractive organism in the study of human diseases. Epilepsy is one of the most common neurological disorders, which is characterized by paroxysmal electrical disturbances of the brain that are manifested as seizures. Most epilepsy researchers have chosen to limit their studies to mammalian organisms, such as mo...
