When anticonvulsant drugs fail to control epilepsy, surgery can be used as a last resort: removing the part of the brain thought to be the source of someone’s seizures.
Unfortunately, this doesn’t always work. A computer model of brain activity could change things for the better by allowing surgeons to more precisely tailor the procedure to the individual.
Seizures are caused by sudden surges in electrical activity in the brain. EEG scans made during a seizure can capture what is going on, providing a clue to the part of the brain that needs to be cut out. Even so, the surgery still fails to prevent seizures in 30 per cent of cases.
