Binocular rivalry minus blank baseline.

<p>Figure follows the same format as <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0020367#pone-0020367-g003" target="_blank">Figure 3</a>, but results are for binocular rivalry (BR) minus the blank baseline condition. (A) As with monocular rivalry, binocular rivalry showed a U-shaped function of activation as a function of contrast; there was higher activation in a number of different areas at 9% and 36%. Abbreviations: inferior frontal cortex (IF); lateral occipital cortex (LO); middle frontal cortex (MF); premotor cortex (PM); superior parietal cortex (SP); supplementary motor area (SMA); temporoparietal junction (TPJ). (B) The region of interest analysis also confirmed that binocular rivalry showed a U-shaped function of activation as a function of contrast in many areas, particularly V2 and V3.
