A review pointed out that Vidal's 1973 paper stated the "BCI challenge" of controlling external objects using EEG signals, and especially use of Contingent Negative Variation (CNV) potential as a challenge for BCI control. Vidal is widely recognized as the inventor of BCIs in the BCI community, as reflected in numerous peer-reviewed articles reviewing and discussing the field (e.g., ). UCLA Professor Jacques Vidal coined the term "BCI" and produced the first peer-reviewed publications on this topic. To perform the piece one must produce alpha waves and thereby "play" the various percussion instruments via loudspeakers which are placed near or directly on the instruments themselves. The piece makes use of EEG and analog signal processing hardware (filters, amplifiers, and a mixing board) to stimulate acoustic percussion instruments. EEGs permitted completely new possibilities for the research of human brain activities.Īlthough the term had not yet been coined, one of the earliest examples of a working brain-machine interface was the piece Music for Solo Performer (1965) by the American composer Alvin Lucier. However, more sophisticated measuring devices, such as the Siemens double-coil recording galvanometer, which displayed electric voltages as small as one ten thousandth of a volt, led to success.īerger analyzed the interrelation of alternations in his EEG wave diagrams with brain diseases. Berger connected these sensors to a Lippmann capillary electrometer, with disappointing results. These were later replaced by silver foils attached to the patient's head by rubber bandages. He inserted silver wires under the scalps of his patients. Berger was able to identify oscillatory activity, such as Berger's wave or the alpha wave (8–13 Hz), by analyzing EEG traces.īerger's first recording device was very rudimentary. In 1924 Berger was the first to record human brain activity by means of EEG. The history of brain–computer interfaces (BCIs) starts with Hans Berger's discovery of the electrical activity of the human brain and the development of electroencephalography (EEG). ![]() 4.4 Synthetic telepathy/silent communication.4.3.10.2 Bio/neurofeedback for passive BCI designs.4.3.10 BCI control strategies in neurogaming.4.3.7 Prosthesis and environment control. ![]()
