Although the schizophrenia and bipolar disorder share a number of overlap in clinical features, they are conceptualized as separate disease, and it is still uncertainty about the common and distinct neural substrates of each. Fifty-three schizophrenia patients, sixy-seven bipolar disorder patients and fifty-nine normal controls were scanned with resting-state functional MRI on a 3T. Regional low-frequency BOLD signal oscillations were used to identified regional functional deficits in these patients. Our findings revealed that the regional functional deficits of the two disease are quite different and involving two different neural network.
