Structural features of the amygdala and hippocampus in controls and in ipsilateral and contralateral sides of HS patients. (A) Structural features of hippocampus; (B) structural features of amygdala; (C) normalized temporal horn volume; (D) Gray-white matter blurring in the temporal pole. Red lines represent the mean values (solid circles) and standard deviations (two ends); *: P<0.05; **: P<0.01; ***: P<0.001; n.s.: non-significant. All P values were adjusted for multiple comparison using FDR method. HippoFLAIR, normalized FLAIR signal intensity of hippocampus; AmygVol, normalized volume of Amygdala; AmygFLAIR, normalized FLAIR signal intensity of amygdala; TempoHornVol, normalized volume of temporal horn of lateral ventricle; TempoPoleBlur, GM/WM boundary blurring in temporal pole; Con, control group; Ipsi-HS, ipsilateral side of HS patient group; Con-HS, contralateral side of HS patient group.
