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. Research on BCIs began in the 1.

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. 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.

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. 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. 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. Prominent research successeseditKennedy and Yang DaneditPhillip Kennedy who later founded Neural Signals in 1. Booting WikipediaQuick boot redirects here. For the feature of the Quarterdeck memory manager, see Quickboot QEMM. This article is about bootstrapping operating systems. For the general concept, see Bootstrapping. In computing, booting or booting up is the initialization of a computerized system. The system can be a computer or a computer appliance. The booting process can be hard, e. CPU is switched from off to on in order to diagnose particular hardware errors, or soft, when those power on self tests POST can be avoided. On some systems a soft boot may optionally clear RAM to zero. Both hard and soft booting can be initiated by hardware such as a button press, or by software command. Booting is complete when the normal, operative, runtime environment is attained. A boot loader is a computer program that loads an operating system or some other system software for the computer after completion of the power on self tests it is the loader for the operating system itself. Within the hard reboot process, it runs after completion of the self tests, then loads and runs the software. A boot loader is loaded into main memory from persistent memory, such as a hard disk drive or, in some older computers, from a medium such as punched cards, punched tape, or magnetic tape. The boot loader then loads and executes the processes that finalize the boot. Like POST processes, the boot loader code comes from a hard wired and persistent location if that location is too limited for some reason, that primary boot loader calls a second stage boot loader or a secondary program loader. On modern general purpose computers, the boot up process can take tens of seconds, or even minutes, and typically involves performing a power on self test, locating and initializing peripheral devices, and then finding, loading and starting an operating system. The process of hibernating or sleeping does not involve booting. Minimally, some embedded systems do not require a noticeable boot sequence to begin functioning and when turned on may simply run operational programs that are stored in ROM. All computing systems are state machines, and a reboot may be the only method to return to a designated zero state from an unintended, locked state. In addition to loading an operating system or stand alone utility, the boot process can also load a storage dump program for diagnosing problems in an operating system. Boot is short for bootstrap12 or bootstrap load and derives from the phrase to pull oneself up by ones bootstraps. The usage calls attention to the requirement that, if most software is loaded onto a computer by other software already running on the computer, some mechanism must exist to load the initial software onto the computer. Early computers used a variety of ad hoc methods to get a small program into memory to solve this problem. The invention of read only memory ROM of various types solved this paradox by allowing computers to be shipped with a start up program that could not be erased. Growth in the capacity of ROM has allowed ever more elaborate start up procedures to be implemented. Historyedit. Switches and cables used to program ENIAC 1. There are many different methods available to load a short initial program into a computer. These methods reach from simple, physical input to removable media that can hold more complex programs. Pre integrated circuit ROM exampleseditEarly computerseditEarly computers in the 1. An early computer, ENIAC, had no program stored in memory, but was set up for each problem by a configuration of interconnecting cables. Bootstrapping did not apply to ENIAC, whose hardware configuration was ready for solving problems as soon as power was applied. In 1. 96. 0, the Ballistic Missile Early Warning System Display Information Processor DIP in Colorado Springsbefore the NORAD facility was built in the underground Cheyenne Mountain Complexran only one program, which carried its own startup code. The program was stored as a bit image on a continuously running magnetic drum, and loaded in a fraction of a second. Core memory was probably cleared manually via the maintenance console, and startup from when power was fully up was very fast, only a few seconds. In its general design, the DIP compared roughly with a DECPDP 8. Thus, it was not the kind of single button pres bootstrap that came later, nor a read only memory ROM in strict terms, since the magnetic drum involved could be written to. First commercial computerseditThe first programmable computers for commercial sale, such as the UNIVAC I and the IBM 7. They typically included instructions that performed a complete input or output operation. The same hardware logic could be used to load the contents of a punch card the most typical ones or other input media, such as a magnetic drum or magnetic tape, that contained a bootstrap program by pressing a single button. This booting concept was called a variety of names for IBM computers of the 1. IBM used the term Initial Program Load with the IBM 7. Stretch6 and later used it for their mainframe lines, starting with the System3. Initial program load punched card for the IBM 1. The IBM 7. 01 computer 1. Load button that initiated reading of the first 3. Load Selector switch. The left 1. 8 bit half word was then executed as an instruction, which usually read additional words into memory. Download Hoover Dimension Supreme Manual'>Download Hoover Dimension Supreme Manual. The loaded boot program was then executed, which, in turn, loaded a larger program from that medium into memory without further help from the human operator. The term boot has been used in this sense since at least 1. IBM System3 console from the 1. Program load selector switch is lower left Program load switch is lower right. Other IBM computers of that era had similar features. For example, the IBM 1. The 8. 0 characters stored in the punched card were read into memory locations 0. This instruction was always the same move the information in these first 8. Once this information was moved to the assembly area, the machine would branch to an instruction in location 0. Another example was the IBM 6. Thus setting the switches to 7. IBMs competitors also offered single button program load. The CDC 6. 60. 0 c. PP 0 and initiated the load sequence. PP 0 loaded the necessary code into its own memory and then initialized the other PPs. The GE 6. 45 c. 1. SYSTEM BOOTLOAD button that, when pressed, caused one of the IO controllers to load a 6. The first model of the PDP 1. READ IN button that, when pressed, reset the processor and started an IO operation on a device specified by switches on the control panel, reading in a 3. A noteworthy variation of this is found on the Burroughs. B1. 70. 0 where there is neither a bootstrap ROM nor a hardwired IPL operation. Instead, after the system is reset it reads and executes opcodes sequentially from a tape drive mounted on the front panel this sets up a boot loader in RAM which is then executed. However, since this makes few assumptions about the system it can equally well be used to load diagnostic Maintenance Test Routine tapes which display an intelligible code on the front panel even in cases of gross CPU failure. IBM System3. 60 and successorseditIn the IBM System3. Architecture machines, the boot process is known as Initial Program Load IPL. IBM coined this term for the 7. Stretch,6 revived it for the design of the System3.
