FIGURE 5. Correlations Betw een Anhedonia Score and Brain Activity in the Left and Right Dorsolateral Prefrontal Cortex in 2 0 Patients With Schizophrenia During the Delay Phase of Trials With Pleasant Picturesa.

FIGURE 5

a The regions of interest in the dorsolateral prefrontal cortex were obtained by isolating two clusters of voxels that showed greater activity in comparison subjects than in patients during the delay phase of task trials with pleasant stimuli. The left region of interest was a cluster of 50 voxels isolated from a cluster with a local maximum peak at coordinates –18, 52, 34 in the Montreal Neurological Institute system, while the right region of interest included 41 voxels with the peak at 48, 16, 34. Both correlation coefficients were negative (−0.47 and −0.33, respectively), although only the one for activity on the left reached statistical significance (df=18, p=0.04 and p=0.16, respectively, two-tailed).
