Fig. 3From: Measuring visual electrophysiological responses in individuals with low-functioning autism: a feasibility and pilot studyTopographical maps showing the distribution of prestimulus (−500 to 0 ms) and poststimulus (4 to 500 ms) spectral power in the alpha and theta bands for the three participant groups. LFA low-functioning autism, HFA high-functioning autism, TD typical development. Spectral power is color-coded as shown in the color bar with red representing the highest level of spectral power and blue representing the lowest level of spectral powerBack to article page
