From: Snakes elicit specific neural responses in the human infant brain
Time-domain representation of frog and snake-selective responses during fast periodic visual stimulation. (A) Grand averages of the notch-filtered EEG responses relative to the onset of the frog and snake stimuli, at O2. The red line below the waveforms represents the time-points at which the signal significantly deviates from baseline after snake pictures. The grey area indicates the time-window at which the signal significantly differs between frog and snake pictures. Note that the amplitude scale is only approximate due to the epoch-normalization scheme used (see methods). (B) Topographical maps of the P400 evoked by frog and snake stimuli in the time-window at which the signal significantly differs between them (i.e., 420–490 post-stimulus onset).
