The external device calculates the activity of the central nervous system and replaces, restores&nbsp;or intensifies it.Using&nbsp;BCIs, the&nbsp;CNS&nbsp;can control external software&nbsp;such as a computer or hardware such as a prosthetic arm. This allows BCIs to be used as assisted living devices for people with cognitive or sensory-motor functions or in research.&nbsp;<\/p>\n\n\n\n<p>Different sensor modalities can be used to measure&nbsp;CNS&nbsp;activity in BCIs. Electroencephalography (EEG) involves measuring electric currents during synaptic excitations in the neurons. This is achieved by placing&nbsp;non-invasive electrodes&nbsp;on the scalp.&nbsp;By comparison, electrocorticography&nbsp;measures electrical activity in the cerebral cortex by placing electrodes&nbsp;invasively&nbsp;on the surface of the brain.&nbsp;<\/p>\n\n\n\n<p>A BCI system consists of 4 steps:&nbsp;<\/p>\n\n\n\n<ol><li><strong>Signal acquisition<\/strong>&nbsp;\u2013 brain signals are measured using a specific sensor modality. These signals are digitized and sent to a computer.&nbsp;<\/li><li><strong>Feature extraction<\/strong>&nbsp;\u2013 the important signal characteristics are separated from&nbsp;the&nbsp;background signals.&nbsp;<\/li><li><strong>Feature translation<\/strong>&nbsp;\u2013 signal features are converted into appropriate commands for the output device.&nbsp;<\/li><li><strong>Device output<\/strong>&nbsp;\u2013 commands from feature translation activate the external device, providing functionality for the user.&nbsp;<\/li><\/ol>\n\n\n\n<p>BCIs have the potential for routine use in&nbsp;treating&nbsp;patients suffering from severe neuromuscular disorders and&nbsp;in&nbsp;the rehabilitation of people&nbsp;who have suffered a&nbsp;stroke, headinjury&nbsp;or&nbsp;other&nbsp;disorder<strong>.&nbsp;<\/strong>The continued development of BCIs depends on progress in&nbsp;several&nbsp;areas: development of&nbsp;safe&nbsp;and stable signal acquisition hardware, proven BCI reliability in different user populations,&nbsp;and BCI validation. As with the advent of any new healthcare technology, large randomized clinical trials are required to assess the safety and efficacy of BCIs in patient populations.&nbsp;<\/p>\n\n\n\n<p><strong>Discover the nervous system in detail with the world&#8217;s most advanced 3D anatomy atlas, in addition to detailed models covering the olfactory bulb and the peripheral nerve.
