Enhanced Sympathetic Arousal in Response to fMRI Scanning Correlates with Task Induced Activations and Deactivations
Figure 6
Conjunction of the task induced deactivation (TID) in run 1 and percentage sAA increase immediately prior to scanning.
Left: upper and lower figures represent sagittal and coronal slices of an anatomical spatially normalized mean image of all subjects. The middle figure represents a dorsal view of a smoothed standard rendered brain. Colour blobs indicate regions that are deactivated during the task and influenced by relative salivary alpha-amylase (sAA) increase. Right: scatter plots and coefficient of determination R2. SFG: superior frontal gyrus; MFG: medial frontal gyrus, Ang. Gy: angular gyri.
