Use of high-frequency visual stimuli above the critical flicker frequency in a SSVEP-based BMI

Use of high-frequency visual stimuli above the critical flicker frequency in a SSVEP-based BMI

Highlights • High-frequency visual stimuli above the critical flicker frequency (CFF) were used to develop a steady-state visual evoked potential (SSVEP)-based brain–machine interface (BMI). • Participants showed high classification accuracy (approximately 90%) in controlling the SSVEP-based BMI sys...

Zusammenfassung:Highlights • High-frequency visual stimuli above the critical flicker frequency (CFF) were used to develop a steady-state visual evoked potential (SSVEP)-based brain–machine interface (BMI). • Participants showed high classification accuracy (approximately 90%) in controlling the SSVEP-based BMI system even when the high-frequency stimulus flickered invisibly. • Visual fatigue occurring after presentation of visibly flickering stimuli was not observed after high-frequency stimuli above the CFF.
