Resting state functional magnetic resonance imaging study of amplitude of low-frequency fluctuation and fractional amplitude of low-frequency fluctuation in schizophrenia with violent behaviors

Objective To study the characteristics of spontaneous neural activity of schizophrenia patients under resting state,and to explore the neuropathological mechanism of brain dysfunction in schizophrenia with violent behaviors based on the methods of the amplitude of low frequency fluctuation (ALFF) and the fractional amplitude of low frequency fluctuation (fALFF),using resting state functional magnetic resonance imaging (rs-fMRI).
