Summary

This research study is designed to look at the involvement of the glutamate system and synaptic density in depression and bipolar disorder. Each participant will undergo a screening appointment to determine study eligibility. Thereafter, the study will take 2 or 3 visits depending on schedule availability and will consist of a combination of one magnetic resonance imaging (MRI) or functional magnetic resonance imaging (fMRI) scan, one proton magnetic resonance spectroscopy (MRS) and/or one C13 MRS scans, and up to two positron emission tomography (PET) scans. Participants will also participate in cognitive testing. Depending on camera time, staff availability and subject schedule, total study participation may last 1-2 months.
