Rice University study finds possible clues to epilepsy, autism

Researchers at Rice University have identified a potential connection between glutamate and phosphoinositide 3-kinase (PI3K) in the development of neurological disorders. A mutation in a glutamate receptor gene found in both fruit flies and humans can disrupt regulatory mechanisms, leading to increased neuronal excitability.
