About 50 million people suffer from epilepsy in the world, one-third of whom do not respond to drug treatment. In many cases it is advisable to perform a surgical intervention on the point of the brain where seizures originate, but first the exact location must be found, which proves a complex and laborious task. In order to improve this process, two UPF researchers are developing the prototype of a new computer program called BrainFocus,which allows finding the epileptic focal point more accurately and more simply than conventional methods, saving up to 90% of the time.
