Fig. 3From: Driving steady-state visual evoked potentials at arbitrary frequencies using temporal interpolation of stimulus presentationSpectrograms of the recorded data averaged over all subjects at the four stimulation frequencies for non-interpolated (top-row) and interpolated (bottom-row) stimulation. Additional signal power was elicited in specific frequency bands when stimulus presentation was interpolated at a refresh rate of 85 Hz (10 and 15 Hz), but not at a refresh rate of 120 Hz (10.63 and 14.17 Hz). 0 dB corresponds to 1 µVBack to article page
