Recently, it has been shown that individual classification of subjects across scans is possible using correlation matrices derived from their resting state data. In the current study, a cohort of patient with major depression and healthy controls each had five resting state fMRI scans over the course of a double blind randomized placebo controlled cross-over ketamine infusion study We apply this classification scheme to our data to see if we can link individual functional connectivity profiles to behavioral improvements after ketamine.
