Left column: composite waveforms consisting of the transient response added to the envelope of the SSR for all three stimulus durations. The MEG response waveforms for the subsecond stimulus durations were constructed by simply truncating the SSR envelope. Edges in waveforms were not smoothed since this is intrinsically done by the low‐pass filter nature of the HRF. Right column: corresponding energy density functions for each composite waveform.
