The mean strength of resting-state functional connectivity (RSFC) between the left hippocampus and the right dorsolateral frontal region was significantly correlated with different measures of cognitive performance and symptom severity in patients. SZ, schizophrenic patients; HC, healthy controls; DSST, Digit Symbol Substitution Test; WMS-R, Wechsler Memory Scale-Revised; PANSS, Positive and Negative Syndrome Scale; Total, total PANSS score; General, score for general psychopathological syndrome in PANSS.s
