View source for Steady state visually evoked potential

In neurology and neuroscience research, '''steady state visually evoked potentials''' ('''SSVEPs''') are signals that are natural responses to visual [[stimulation]] at specific [[frequency|frequencies]].  When the [[retina]] is excited by a visual stimulus ranging from 3.5&nbsp;[[Hz]] to 75&nbsp;Hz,<ref>{{cite journal |vauthors=Beverina F, Palmas G, Silvoni S, Piccione F, Giove S | year = 2003 | title = User adaptive BCIs: SSVEP and P300 based interfaces | journal = PsychNol. J. | volume = 1 | pages = 331–54 }}</ref> the brain generates electrical activity at the same (or multiples of) frequency of the visual stimulus.
SSVEPs are typically measured using [[EEG|electroencephalography]]. SSVEPs are useful in research because of the excellent [[signal-to-noise ratio]]<ref>D. Regan, Human Brain Electrophysiology: Evoked Potentials and Evoked Magnetic Fields in Science and Medicine, Elsevier, New York, NY, USA, 1989.</ref> and relative immunity to artifacts.<ref>K. E. Misulis, Spehlmann's Evoked Potential Primer, Butterworth-Heinemann, Boston, Mass, USA, 1994.</ref> SSVEPs also provide a means to characterize preferred frequencies of neocortical dynamic processes. SSVEPs are generated by stationary localized sources and distributed sources that exhibit characteristics of wave phenomena.
SSVEPs have been widely used in vision, cognitive neuroscience (e.g., visual attention, binocular rivalry, working memory, alpha range), and clinical neuroscience (e.g., aging and neurodegenerative disorders, schizophrenia, epilepsy) research.<ref>{{Cite journal |last1=Norcia |first1=Anthony M. |last2=Appelbaum |first2=L.
