High up in the hills of Barcelona, brain science start-up Neuroelectrics is developing therapies that it says will improve the lives of people living with brain disease. Its main product is a headcap, which monitors the brain's electrical activity and stimulates regions of the brain with mild electrical currents. Co-founder and CEO Ana Maiques believes it will significantly improve the lives of people suffering with epilepsy. In addition to epilepsy, Maiques and her team are optimistic that the headgear can also be used to treat depression and Alzheimer's. So, when you have epilepsy, you have an electrical discharge in one area of your brain, so they can really target and help them," said Roser Sanchez-Todo, R&D director for Neuroelectrics' brain modelling department.
