Figure 2|ALFF analyses in the individuals who had recovered from COVID-19.
Compared with the HC group, the RecCOVID group demonstrated significantly increased ALFF values in the left precentral gyrus (PreCG), middle frontal gyrus, inferior frontal gyrus of operculum, inferior frontal gyrus of triangle, insula, hippocampus (HIP), parahippocampal gyrus, fusiform gyrus, postcentral gyrus, inferior parietal angular gyrus, supramarginal gyrus, angular gyrus, thalamus, middle temporal gyrus, inferior temporal gyrus, caudate (CAU) and putamen (PUT) (Figure 2A). The left HIP was the peak among the clusters (Figure 2B; cluster size: 78 mm3, peak MNI coordinates: –30, –33, –3, peak t value: 5.4507). More details are provided in Table 3.
