Comparison of activation maps with and without camera motion tracking parameters as regressors.

<p>(Overall FDR = 0.05, cluster threshold = 15 voxels using AlphaSim, t-contrast) The activtion maps were for low concentration (0.016 mM) in awake dogs. The activation map obtained with only SPM realignment parameters as regressors is shown in cool colormap. The activation map with camera motion tracking parameters and SPM realignment parameters as regressors is shown in hot colormap. The common areas are overlaid such that they appear as purple. We found 3 clusters, 379 voxels in cool-colored map (same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0086362#pone-0086362-t003" target="_blank">Table 3</a>); 3 clusters, 396 voxels in hot-colorred map, and 3 clusters, 340 voxels in the common area.
