Abstract: A method and system for individualized target localization for transcranial magnetic stimulation (TMS) in treating depression. The system acquires resting-state functional MRI (R-fMRI) brain imaging data from subjects in both a major depressive disorder (MDD) group and a matching normal control group, followed by data preprocessing.
