Figure 7. Behavioral results of the lesion study.

(a, b, c) the interoceptive performance on the BDT, and (d, e, f) the exteroceptive performance on the DDT. On the BDT, patients with AIC lesions had significantly lower performance in accuracy and dʹ compared with the NC and BDC groups but did not show significant alteration in β during the BDT. On the DDT, patients with AIC lesions did not show significant abnormality in performance in accuracy, dʹ, and β compared with either the NC or BDC groups. NC, normal control; BDC, brain damage control. Dashed line: chance level. * p < 0.05; ** p < 0.01; *** p < 0.001.
