Braincomputer interface Wikipedia. A brain computer interface BCI, sometimes called a mind machine interface MMI, direct neural interface DNI, or brainmachine interface BMI, is a direct communication pathway between an enhanced or wired brain and an external device. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory motor functions. Le Ultime 56 Ore Ita here. Research on BCIs began in the 1. University of California, Los Angeles UCLA under a grant from the National Science Foundation, followed by a contract from DARPA. The papers published after this research also mark the first appearance of the expression braincomputer interface in scientific literature. The field of BCI research and development has since focused primarily on neuroprosthetics applications that aim at restoring damaged hearing, sight and movement. Thanks to the remarkable cortical plasticity of the brain, signals from implanted prostheses can, after adaptation, be handled by the brain like natural sensor or effector channels. Following years of animal experimentation, the first neuroprosthetic devices implanted in humans appeared in the mid 1. HistoryeditThe history of braincomputer interfaces BCIs starts with Hans Bergers discovery of the electrical activity of the human brain and the development of electroencephalography EEG. In 1. 92. 4 Berger was the first to record human brain activity by means of EEG. Berger was able to identify oscillatory activity, such as Bergers wave or the alpha wave 81. Hz, by analyzing EEG traces. Bergers first recording device was very rudimentary. He inserted silver wires under the scalps of his patients. These were later replaced by silver foils attached to the patients head by rubber bandages. Gigi Und Die Braunen Stadtmusikanten there. Berger connected these sensors to a Lippmann capillary electrometer, with disappointing results. 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. Berger analyzed the interrelation of alternations in his EEG wave diagrams with brain diseases. EEGs permitted completely new possibilities for the research of human brain activities. UCLA Professor Jacques Vidal coined the term BCI and produced the first peer reviewed publications on this topic. 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. The 1. 97. 7 experiment Vidal described was noninvasive EEG control of a cursor like graphical object on a computer screen. The demonstration was movement in a maze. After his early contributions, Vidal was not active in BCI research, nor BCI events such as conferences, for many years. In 2. 01. 1, however, he gave a lecture in Graz, Austria, supported by the Future BNCI project, presenting the first BCI, which earned a standing ovation. Vidal was joined by his wife, Laryce Vidal, who previously worked with him at UCLA on his first BCI project. Prof. Vidal also presented a lecture on his early BCI work at the Sixth Annual BCI Meeting, which was scheduled for MayJune 2. Asilomar, California. In 1. 98. 8 report was given on noninvasive EEG control of a physical object, a robot. The experiment described was EEG control of multiple start stop restart of the robot movement, along an arbitrary trajectory defined by a line drawn on a floor. The line following behavior was the default robot behavior, utilizing autonomous intelligence and autonomous source of energy. In 1. 99. 0 report was given on a bidirectional adaptive BCI controlling computer buzzer by an anticipatory brain potential, the Contingent Negative Variation CNV potential. The experiment described how an expectation state of the brain, manifested by CNV, controls in a feedback loop the S2 buzzer in the S1 S2 CNV paradigm. The obtained cognitive wave representing the expectation learning in the brain is named Electroexpectogram EXG. The CNV brain potential was part of the BCI challenge presented by Vidal in his 1.

Versus neuroprostheticseditNeuroprosthetics is an area of neuroscience concerned with neural prostheses, that is, using artificial devices to replace the function of impaired nervous systems and brain related problems, or of sensory organs. The most widely used neuroprosthetic device is the cochlear implant which, as of December 2. There are also several neuroprosthetic devices that aim to restore vision, including retinal implants. The difference between BCIs and neuroprosthetics is mostly in how the terms are used neuroprosthetics typically connect the nervous system to a device, whereas BCIs usually connect the brain or nervous system with a computer system. ERP/34878/ebay/bild.jpg' alt='Heidelberg Machine Serial Number' title='Heidelberg Machine Serial Number' />Practical neuroprosthetics can be linked to any part of the nervous systemfor example, peripheral nerveswhile the term BCI usually designates a narrower class of systems which interface with the central nervous system. The terms are sometimes, however, used interchangeably. Neuroprosthetics and BCIs seek to achieve the same aims, such as restoring sight, hearing, movement, ability to communicate, and even cognitive function. Both use similar experimental methods and surgical techniques. Animal BCI researcheditSeveral laboratories have managed to record signals from monkey and rat cerebral cortices to operate BCIs to produce movement. Monkeys have navigated computer cursors on screen and commanded robotic arms to perform simple tasks simply by thinking about the task and seeing the visual feedback, but without any motor output. In May 2. 00. 8 photographs that showed a monkey at the University of Pittsburgh Medical Center operating a robotic arm by thinking were published in a number of well known science journals and magazines. Other research on cats has decoded their neural visual signals. Microsoft Forefront Client Security Windows 7 64 Bit. Early workedit. Monkey operating a robotic arm with braincomputer interfacing Schwartz lab, University of PittsburghIn 1. Fetz and colleagues, at the Regional Primate Research Center and Department of Physiology and Biophysics, University of Washington School of Medicine in Seattle, showed for the first time that monkeys could learn to control the deflection of a biofeedback meter arm with neural activity. Similar work in the 1. Studies that developed algorithms to reconstruct movements from motor cortexneurons, which control movement, date back to the 1. In the 1. 98. 0s, Apostolos Georgopoulos at Johns Hopkins University found a mathematical relationship between the electrical responses of single motor cortex neurons in rhesus macaque monkeys and the direction in which they moved their arms based on a cosine function. He also found that dispersed groups of neurons, in different areas of the monkeys brains, collectively controlled motor commands, but was able to record the firings of neurons in only one area at a time, because of the technical limitations imposed by his equipment. There has been rapid development in BCIs since the mid 1. Several groups have been able to capture complex brain motor cortex signals by recording from neural ensembles groups of neurons and using these to control external devices.
