UC Irvine neuroscientists have developed a way to stop epileptic seizures with fiber-optic light signals, heralding a novel opportunity to treat the most severe manifestations of the brain disorder. Using a mouse model of temporal lobe epilepsy, Ivan Soltesz, Chancellor’s Professor and chair of anatomy & neurobiology, and colleagues created an EEG-based computer system that activates hair-thin optical strands implanted in the brain when it detects a real-time seizure.
