Schematic of Stimulus Presentation Scheme.

<p>This figure shows a representative schematic of the stimulus presentation scheme including mean luminance periods using the orderly presented wedge stimulus as an example. <b>A)</b> Shows a standard wedge aperture located at 0° revealing a checkerboard pattern. The wedge turns counter-clockwise. <b>B)</b> Shows a color-code for each of the twelve wedge positions presented during stimulation. <b>C)</b> Shows the timecourse of stimulus presentation for three exemplary cycles. The entire stimulation consists of 15 such cycles. The colors of the squares correspond to the color of the wedge position shown at a certain moment in time lasting for two seconds ( = 1TR). Grey squares indicate mean luminance periods.
