DOI: 10.1088/1741-2552/abf522
Abstract: Objective. Error-related potentials (ErrPs) are spontaneous electroencephalogram signals related to the awareness of erroneous responses within brain domain. ErrPs-based correction mechanisms can be applied to motor imagery-brain–computer interface (MI-BCI) to prevent incorrect actions and ultimately… read more here.
