Like all communication methods, it faces the problem of errors in transmission. In the Wadsworth EEG-based brain-computer interface (BCI) system, subjects learn to use mu or beta rhythm amplitude to move a cursor to targets on a computer screen. While cursor movement is highly accurate in trained subjects, it is not perfect. %B Clinical neurophysiology : official journal of the International Federation of Clinical Neurophysiology %V 111 %P 2138–2144 %8 12/2000 %G eng %U http://www.ncbi.nlm.nih.gov/pubmed/11090763 %R 10.1016/S1388-2457(00)00457-0
