Abstract
After 40 years of investigation, steady-state visually evoked potentials (SSVEPs)
have been shown to be useful for many paradigms in cognitive (visual attention, binocular
rivalry, working memory, and brain rhythms) and clinical neuroscience (aging, neurodegenerative
disorders, schizophrenia, ophthalmic pathologies, migraine, autism, depression, anxiety,
stress, and epilepsy). Recently, in engineering, SSVEPs found a novel application
for SSVEP-driven brain-computer interface (BCI) systems. Although some SSVEP properties
are well documented, many questions are still hotly debated. We provide an overview
of recent SSVEP studies in neuroscience (using implanted and scalp EEG, fMRI, or PET),
with the perspective of modern theories about the visual pathway. We investigate the
steady-state evoked activity, its properties, and the mechanisms behind SSVEP generation.
Next, we describe the SSVEP-BCI paradigm and review recently developed SSVEP-based
BCI systems. Lastly, we outline future research directions related to basic and applied
aspects of SSVEPs.
