Fig. 1: Visual stimulation and experimental paradigm.

A Representative frame of baseline grey screen (upper row, stimulus ‘off’) and reversing checkerboard (lower row, stimulus ‘on’) for RS condition. The small black square indicates the fixation point. B Representative frame of low-contrast (20%) grey-scale baseline animated cartoon (upper row, stimulus ‘off’) and blended checkerboard-cartoon (lower row, stimulus ‘on’) for Cartoon-Fixed (CF) and Cartoon Chosen (CC) conditions. C Representative HDR in the occipital cortex during the stimulus ‘off’ (upper row) and stimulus ‘on’ activation phase (lower row) according to the output of nirsLAB software. The Look Up table is reported under the images. D Experimental protocol showing that the cycles of visual stimulation were structured in blocks of 40 trials (20 trials with the reversing checkerboard and 20 trials with the ‘mock’ stimulus) for a total duration of 10 min.
