Figure 2.

(a) Effects of delta-9-THC and CBD on inferior frontal connectivity (brain on the left side of panel; cross-hairs) with parahippocampal gyrus (brain on the right side of panel; cross-hairs) during visual oddball salience processing. The left side of the brain is shown on the left side of the images. (b) The bar graph (mean±SEM) shows that connectivity of the inferior frontal seed cluster with the parahippocampal gyrus (y axis; arbitrary units) in (a) was augmented by delta-9-THC but attenuated by CBD.
