Fig. 3: Activation map of the convolutional neural network model.

a Example of an activation map overlaid on the corresponding PET image. b Violin plot of the mean activation values of the five regions of interests (ROIs) based on the structural atlas (center line, median; lines above and below the center line, upper and lower quartiles). c Violin plot of the mean activation values of the three ROIs based on the connectivity atlas. Vent. ventral, Ant. anterior, Pos. posterior. The ROIs are shown on a PET image next to the violin plots. P-values: <0.05 (*), <0.01 (**), <0.001 (***).
