Brain–computer interface

Brainstorm is a 1983 American science fiction film directed by Douglas Trumbull, and starring Christopher Walken, Natalie Wood (in her final film role), Louise Fletcher, and Cliff Robertson.

Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The bio signals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp EEG") using the International 10–20 system, or variations of it. Electrocorticography, involving surgical placement of electrodes, is sometimes called "intracranial EEG". Clinical interpretation of EEG recordings is most often performed by visual inspection of the tracing or quantitative EEG analysis.

Eduardo Reck Miranda (born 1963) is a Brazilian composer of chamber and electroacoustic pieces but is most notable in the United Kingdom for his scientific research into computer music, particularly in the field of human-machine interfaces where brain waves will replace keyboards and voice commands to permit the disabled to express themselves musically.

Miguel Ângelo Laporta Nicolelis (born March 7, 1961), MD, PhD, is a Brazilian scientist and physician, best known for his pioneering work in "reading monkey thought". He and his colleagues at Duke University implanted electrode arrays into a monkey's brain that were able to detect the monkey's motor intent and thus able to control reaching and grasping movements performed by a robotic arm. This was possible by decoding signals of hundreds of neurons recorded in volitional areas of the cerebral cortex while the monkey played with a hand-held joystick to move a shape in a video game. These signals were sent to the robot arm, which then mimicked the monkey's movements and thus controlled the game. After a while the monkey realised that thinking about moving the shape was enough and it no longer needed to move the joystick. So it let go of the joystick and controlled the game purely through thought. A system in which brain signals directly control an artificial actuator is commonly referred to as brain-machine interface or brain-computer interface.

The Atari Mindlink is an unreleased video game controller for the Atari 2600, originally intended for release in 1984. The Mindlink was unique in that its headband form factor controls the game by reading the myoneural signal voltage from the player's forehead. The player's forehead movements are read by infrared sensors and transferred as movement in the game.

HI, LLC, doing business as Kernel, is an American company that has developed a non-invasive neuroimaging technology. It is a privately held company headquartered in Los Angeles, California. The company was founded in 2016 by Bryan Johnson.

Neuralink Corp. is an American neurotechnology company that has developed, as of 2024, implantable brain–computer interfaces (BCIs). It was founded by Elon Musk and a team of eight scientists and engineers. Neuralink was launched in 2016 and was first publicly reported in March 2017.

Ryan C.N. D'Arcy (born 1972) is a Canadian neuroscientist. He is a full professor at Simon Fraser University, where he holds the B.C. Leadership Chair in Multimodal Technology for Healthcare Innovations. He is also the head of Health Sciences and Innovation at Fraser Health's Surrey Memorial Hospital.

NeuroSky, Inc. is a manufacturer of brain-computer interface (BCI) technologies for consumer product applications, which was founded in 2004 in Silicon Valley, California. The company adapts electroencephalography (EEG) and electromyography (EMG) technology to fit a consumer market within a number of fields such as entertainment (toys and games), education, automotive, and health.

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 device.)
