Spatiotemporal cluster analysis of cortical current estimates.

<p>Results of the spatiotemporal cluster analysis on the cortical current estimates data for Face and Body perception, visualized on the inflated cortical surface. Columns represent different time windows, rows represent different contrasts. Each cell displays both the spatial and temporal extent of each cluster. The visualization of the inflated cortical surface is equivalent to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0071408#pone-0071408-g003" target="_blank">Figure 3</a> (see figure legend 3D), with left hemisphere on the left and right hemisphere on the right. The graphs below the cortical maps represent the temporal courses of the size of each cluster (in number of dipoles) and their p-value, in the left and right hemisphere. In the case of multiple clusters, the red, blue and green colors indicate corresponding clusters in the cortical map (circles) and time course. <b>A</b>. <i>Body Sensitivity</i> was analysed with the contrast Bodies>Scrambled Bodies (<i>n</i> = 10, one-sided, <i>α</i> = 0.05). <b>B</b>. <i>Face sensitivity</i> was analysed with the contrast Faces>Scrambled Faces (<i>n</i> = 10, one-sided, <i>α</i> = 0.05). <b>C</b>. Body and face selectivity was analysed by directly contrasting Bodies with Faces (<i>n</i> = 10, two-sided, <i>α</i> = 0.025 for each side). Clusters with preferred responses to Bodies are indicated in yellow/red; clusters with preferred responses to Faces in blue.
