Neural Impulse Actuator : ウィキペディア英語版 | Neural Impulse Actuator The Neural Impulse Actuator (NIA) is a brain–computer interface (BCI) device developed by OCZ Technology. BCI devices attempt to move away from the classic input devices like keyboard and mouse and instead read electrical activity from the head, preferably the EEG. The name Neural Impulse Actuator implies that the signals originate from some neuronal activity; however, what is actually captured is a mixture of muscle, skin and nerve activity including sympathetic and parasympathetic components that have to be summarized as biopotentials rather than pure neural signals. As of May 27, 2011, the OCZ website says that the NIA is no longer being manufactured and has been end-of-lifed.〔()〕 On June 1, 2012 a post was made on the official forums, asking about the NIAs future,〔http://www.ocztechnologyforum.com/forum/showthread.php?101982-Is-the-NIA-dead〕 the reply being, "It (NIA ) was spun out into a different company as a side-effect of OCZ's IPO and that company is (BCInet ).".〔http://www.ocztechnologyforum.com/forum/showthread.php?101982-Is-the-NIA-dead&p=735215&viewfull=1#post735215〕 == Name == The name Neural Impulse Actuator is still justifiable since also the secondary signals are under neuronal control. The biopotentials are decompiled into different frequency spectra to allow the separation into different groups of electrical signals. Individual signals that are isolated comprise alpha and beta brain waves, electromyograms and electro oculograms. The current version of the NIA uses carbon-fibers injected into soft plastic as substrate for the headband and for the sensors and achieves sensitivity much greater than the original silver chloride-based sensors using a clip-on interface to the wire harness.
