Abnormal activation patterns in mt+ during visual motion perception in major depressive disorder

HIGHLIGHTS

• What: The authors utilized psychophysical experiment and ultra-high field 7 T MRI to explore the brain function of the visual cortex in MDD patients during a visual grating motion perception task, based on the classic task-state fMRI . In this study, compared to HC group, beta value and percent signal change in both left and right MT+ were decreased in MDD patients in the between-group comparison. In this analysis, the authors conducted statistical analyses across the whole brain based on the seed region left MT+, and identified calcarine fissure and surrounding cortex and precuneus as . . .
