Study: NCT02278328

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: STX209 (15mg)
Description: A randomized acute dose-response design will be employed with a total study duration of 3 weeks. At each visit, baseline MEG will be obtained followed by acute single-dose drug/placebo administration, followed 60 minutes later by repeat MEG. Each participant will receive a single dose of placebo in random order and a single dose of STX209 from smallest to largest (15mg, and 30mg). MRI and MRS will be performed immediately following MEG to provide an anatomic basis for source localization as well as to assess acute effects of STX209 administration on MRS estimates of GABA and glutamate. The STX209 (15mg) intervention is the low dose
