Areas showing significant correlations with single auditory and visual features.

<p>The color coding as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035215#pone-0035215-g008" target="_blank">Figure 8</a>. Results are thresholded at p < 0.001. A: Speech explains activity in the superior temporal sulcus (STS) and middle temporal gyrus (MTG), lip representation area of the primary motor cortex (M1L) and ptIFG particularly in the left hemisphere, and dorsomedial PFC. Partially overlapping areas also show activity correlated with music. RMS energy explains activity in the superior temporal areas, particularly in a part of the posterior bank of Heschl’s gyrus (in or in the vicinity of the primary auditory cortex) and/or Planum Temporale. Other sound categories are not significantly correlated with activity in this region. The black outline indicates the area encompassing the Heschl’s gyrus (HG) of all subjects visually identified from the standardized structural images. Bar graphs show the correlation coefficients for each stimulus feature in the non-overlapping areas. Colors of the bars refer to the brain areas best activated with one of the three stimulus features. B: Hand motion activates strongly IPS and TOJ. The areas are very similar to those included in IC6 (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035215#pone-0035215-g007" target="_blank">Figure 7</a>). Superior occipital cortex (sOC), occipital pole (OP), and parts of the lateral occipital cortex (lOC) show specific activity to body motion. Activity in the occipital pole also correlated with the contrast edges of the image.
