Results of amplitude of low-frequency fluctuations analysis. The comparison between baseline PSSA patients and HCs are shown at the top. Compared to HCs, PSSA patients showed decreased ALFF in the left TP and increased ALFF in the left AG, right SMG, and right IFG. Left TP ALFF value was positively correlated with WAB AQ (p = 0.029), spontaneous speech (uncorrected p = 0.015, FDR p = 0.038), and naming (uncorrected p = 0.019, FDR p = 0.038) scores. The comparison between PSSA patients in session 1 and session 2 was shown on the bottom. PSSA patients showed significantly increased ALFF in the left TP (p = 0.05) after one month. The left TP ALFF change is positively and significantly correlated with WAB AQ change (p = 0.029) in the patients. Note that due to partial correlations, axes show the residuals of parameters. Abbreviations: ALFF: amplitude of low-frequency fluctuations; TP: temporal pole; AG: angular gyrus; SMG: supramarginal gyrus; IFG: inferior frontal gyrus. ‘*’ indicates statistical significance.
