From: Functional magnetic resonance imaging (fMRI) changes and saliva production associated with acupuncture at LI-2 acupuncture point: a randomized controlled study

Figure 3

Specific activation by true acupuncture versus placebo acupuncture. Activation regions shown by fMRI signals associated with true acupuncture were compared to those from sham acupuncture. Panel 3a: sagittal, coronal and axial view (respectively) of activation in the insula and adjacent operculi. Panel 3b: Correlation of saliva production with ROI volumes.
