A Task structure. Participants viewed ambiguous images presented for one minute at a time, and pressed buttons to indicate their alternating percepts. They were allowed to answer “unsure” for mixed percepts. The Necker cube and face-vase images were created by one of the authors (B.J.H.) and published in a previous study33. B Percentage of time spent in each of the possible percepts for the two images. Shown as a violin plot, which includes features of a boxplot (thick circle indicates median, thick black line is the inter-quartile range, and thin black line extend to the most extreme data points not considered outliers), as well as a density estimate of the distribution. Each thin circle represents one participant (n = 14). Significant difference in percentage time between the two percepts of an image was assessed with a two-sided Wilcoxon sign-rank test. C Electrode locations for all participants. Electrodes on the left hemisphere were mapped onto the right hemisphere for visualization purpose only. For electrode coverage in individual patients see Supplementary Fig. 1. Source data are provided as a Source Data file.
