Topographic segmentation.

<p>The global field power (GFPs) of the grand average ERPs are shown for radial and parallel motion in the scrambled motion (respectively rSM and lSM) and biological motion conditions (respectively rBM and lBM) over the first 500ms. The topographic segmentation procedure performed on rSM, lSM, rBM and lBM together identified 5 segment maps that best explained the map series of the 4 conditions. These 5 segment maps, numbered Map1 to Map5 are represented on the column on the right and are outlined with different colors. Their times of appearance are indicated by the corresponding color in the area below the GFP in each of the 4 conditions.
