| Steady-State Visual Evoked Potentials (SSVEP) are EEG brain responses that are precisely synchronized with fast (e.g. more than 4Hz) repetitive external visual stimulation such as flashes, reversing patterns or luminance-modulated images. SSVEP responses can be measured within narrow frequency bands (such as ±0.1 Hz) around the visual stimulation frequency, or using other signal processing methods that exploit the specific characteristics of the SSVEP signal, such as rhythmicity and synchronization. The strongest responses occur in the primary visual (striate) cortex, although other brain areas are also activated in varying degrees. |
