Brain implant  From Wikipedia, the free encyclopedia Jump to:
navigation, search  Brain implants, often referred to as neural
implants, are technological devices that connect directly to a
biological subject's brain - usually placed on the surface of
the brain, or attached to the brain's cortex. A common purpose
of modern brain implants and the focus of much current research
is establishing a biomedical prosthesis circumventing areas in
the brain that have become dysfunctional after a stroke or other
head injuries. This includes sensory substitution, e.g., in
vision. Other brain implants are used in animal experiments
simply to record brain activity for scientific reasons. Some
brain implants involve creating interfaces between neural
systems and computer chips. This work is part of a wider
research field called brain-computer interfaces. (Brain-computer
interface research also includes technology such as EEG arrays
that allow interface between mind and machine but do not require
direct implantation of a devi
