Figure 1. Condition contrasts.

The glass brains and coronal images show the effects across groups of the following contrasts: explicit – exciting (left, top row), erotic – exciting (middle, middle row) and money – exciting (right, bottom row). The images are shown at whole-brain FWE-corrected P<0.05. The axial view (top right) shows the contrast across groups of explicit – exciting videos focusing on the substantia nigra. The image is shown with a substantia nigra region of interest mask overlaid on a magnetization transfer sequence.
