Brain Computer Interface

Abstract—Brain-computer interface (BCI) is a fast-growing emergent technology, in which researchers aim to build a direct channel between the human brain and the computer.The device was designed to help those who have lost control on their limbs, or other bodily functions, such as patients with amyotrophic lateral sclerosis (ALS) or spinal cord injury A Brain Computer Interface (BCI) is a collaboration in which a brain accepts and controls a mechanical device as a natural part of its representation of the body. Computer-brain interfaces are designed to restore sensory function, transmit sensory information to the brain, or stimulate the brain through artificially generated electrical signals.A brain-computer interface is a new communication link between a functioning human brain and the outside world. BCI uses brain activity to command, control, actuate and communicate with the world directly through brain integration with peripheral devices and systems. The signals from the brain are taken to the computer via the implants for data entry without any direct brain intervention. BCI transforms mental decisions and/or reactions into control signals by analysing the bioelectrical brain activity. Keywords—BCI, Bioelectrical Brain activity, ALS
