It can detect and terminate seizures before the clinical symptoms occur, provide stimulation only when needed, can be turned off if seizures disappear; it has minimal side effects -- as a matter of fact, in all our clinical trials to date, we've seen no side effects in the 40 or so patients in whom it's been implanted -- and it's invisible, cosmetically hidden, so, if you have epilepsy and you have the device, no one will know it because you can't tell that it's there.
