Group comparison (controls > recAN) of the brain BOLD signals during the weight estimation task. a The cluster rendered on the sagittal brain section shows the group effect (control > recAN) in the weight estimation task on BOLD signals in the middle temporal gyrus corresponding to the extrastriate body area (EBA, Brodmann’s area 37). The maximum peak of the effect at the MNI coordinates: x = 48, y = − 58, z = − 2 mm; cluster size: k = 131 voxels; peak T score = 4.49, height level: p = 1.39 × 10^− 5 (uncorrected), cluster level: p = 0.029; FDR corrected for multiple comparisons. The analyses were on a whole brain exploratory voxel-by-voxel basis. The left color bar indicates the T value of the rendered cluster. b The bar graph shows the parametric estimates of the BOLD signals in the right EBA cluster in each group (recAN and controls) for each stimulus type (underweight, healthy weight, and overweight). Post hoc t-tests showed significantly greater BOLD signals in controls than in patients with recAN, regardless of the stimulus types. Error bars indicate standard error. * p < 0.05, ** p < 0.01 (Bonferroni-corrected). MNI: Montreal Neurological Institute; BOLD: blood oxygen level dependent; FDR: false discovery rate; recAN: recovered anorexia nervosa
