The maps of gender-related fALFF differences in PI patients’ brain regions. R: right brain. a: right cerebellum posterior lobe, b: right superior temporal gyrus, c: left middle frontal gyrus. All regions shown reached a voxel-level significance threshold of P < .001, FWE correct P = .05, cluster size >50. Negative t-value suggested male PI patients had lower fALFF values in this area than female PI patients. fALFF = fractional amplitude of low-frequency fluctuations, PI = primary insomnia.
