Study Summary

The purpose of this study is to assess the relative feasibility of 2 potential functional measures of target engagement (Glx MRS, BOLD fMRI) to systematically assess mGluR 2/3 in drug development for psychotic spectrum disorders.

Primary Outcome

Compare changes in Glx response to infusion of ketamine vs placebo, as measured by proton magnetic resonance spectroscopy (¹H MRS). Calculated by post-pre changes in the Glx over creatinine ratios, with higher values indicating higher Glx/creatinine ratios.
