Graphene-based brain implant detects more activity than electrodes
Implant uses a transistor-based architecture that amplifies the brain’s signals in situ.
Records electrical activity in the brain over large areas and at frequencies below 0.1Hz.
Slim and flexible enough to be used over large areas of the cortex.
Can support many more recording sites than a standard electrode array.
Low-frequency brain activity carries crucial information such as the onset of strokes.
New generation of brain-computer interfaces could repair high-level cognitive functions.
Developed by Graphene Flagship.
