TITLE : The Amplitude of Low Frequency Fluctuations in Slow - 4 vs . Slow - 5 Passbands in Auditory and Visual Hallucinators with Schizophrenia

INTRODUCTION: Measured low frequency fluctuations in resting state BOLD fMRI signals are correlated with spontaneous neuronal activity and abnormal fluctuation patterns have previously been reported in patients with schizophrenia (SZ). While there is a growing literature on abnormal resting-state dynamics in SZ, relatively little is known about the pathophysiology underlying particular symptoms like hallucinations. Measuring the mean amplitude of low frequency fluctuations (ALFF) in chronic hallucinators across different frequency passbands can enhance our understanding of the functional and behavioral impact of these low-frequency oscillations.
