Separation of luminance and contrast modulation in steady-state visual evoked potentials

Year: 2025

Type: article

Abstract: ) at three frequencies (3, 5, 7.14 Hz) to evaluate the degree to which VEP response non-linearities would affect observed data patterns. With lower contrast modulation at 3 Hz, SSVEP amplitudes and phases correspond to the temporal signatures of contrast - not luminance - modulation. However, at higher frequencies and/or contrasts, this orderly pattern was largely replaced by more complex patterns that no longer directly corresponded to the luminance or contrast of the stimulus.
