A flexible graphene-based neural interface can 'speak and listen' to the brain
Neural interfaces are devices that can detect or modulate neuronal activity when placed in contact with the brain. They are already used to treat various conditions related to the nervous system. However, current technologies still have limitations that can reduce their effectiveness. One example is their unidirectional function. While most existing interfaces can stimulate the brain, they cannot accurately detect or decode brain activity simultaneously. Even when they can do so, they often face
