Brain–computer interfaces (BCI) are units which degree mind task and translate it into messages or instructions, thereby establishing up many chances for research and alertness. This booklet presents keys for realizing and designing those multi-disciplinary interfaces, which require many fields of craftsmanship reminiscent of neuroscience, records, informatics and psychology.
This moment quantity, know-how and functions, is targeted at the box of BCI from the viewpoint of its finish clients, akin to people with disabilities to practitioners. protecting scientific purposes and the sector of games, the booklet then is going directly to discover consumer wishes which force the layout and improvement of BCI. The software program used for his or her layout, essentially OpenViBE, is defined step-by-step, ahead of a dialogue at the use of BCI from moral, philosophical and social perspectives.
The easy notions constructed during this reference ebook are meant to be available to all readers drawn to BCI, no matter what their history. extra complicated fabric can also be provided, for readers who are looking to extend their wisdom in disciplinary fields underlying BCI.

Long-latency potentials (P3 and N400) are indicative of cognitive processes that are activated without explicitly demanding the patient’s attention. These potentials appear as false positives when the clinical behavioral assessment is considered as the ground truth. The existence of these false positives highlights the ambiguity of the results. On the one hand, we know that clinical observations tend to underestimate the level of consciousness of some patients. On the other hand, while the mechanisms underlying these responses have been studied in depth in healthy subjects, they are less known in patients with disorders of consciousness.
FMRI has recently shown that decoding techniques can be used to evaluate the perception of the emotional content of a ﬁlm or a story [NAC 15]. With EEG, playing the patient’s favorite music tracks before electrophysiological assessment could potentially allow the responses evoked by sounds in an oddball paradigm to be more easily detected [CAS 15]. 7. , K ATZ D.
