Main plot: Variance explained in each of the eight layers of the CNN taken alone.

<p>Each waveform represents the average of all 256 electrodes. Lowest layers are in darker colors, and horizontal lines represent statistical significance. Insets, clockwise from top: (1) Onset of statistically significant encoding as a function of CNN layer; (2) maximum variance explained between 101 and 200 ms as a function of CNN layer; (3) maximum variance explained between 0 and 100 ms as a function of CNN layer; (4) maximum variance explained between 101 and 200 ms as a function of CNN layer. Taken together, we can see that early CNN layers explain more variance in ERP patterns, and do so earlier than later CNN layers. All error bars reflect +/- 1 SEM.
