Lead Sponsor: New York State Psychiatric Institute
Brief Summary: 50 healthy volunteers (HV) will participate in 2 identical ketamine-induced pharmacoBOLD (phBOLD) sessions at least 7 days apart. On both days, clinical assessments will be performed following removal of the subject from the scanner.Conditions
HV will be discharged home after clearance by the study physician. This study will assign ketamine doses in successive 10 subject cohorts. The ketamine dose for the 1st cohort will start at 0.08 mg/kg. For subsequent cohorts, the bolus will be successively reduced or increased by 0.02 mg/kg (n=10/dose) to determine the lowest dose of ketamine that still produces a robust phBOLD response.
The study will be subject and rater blind, i.e. subjects and raters, will be blinded to the treatment (ketamine dose) group.
The study physician will be aware of the ketamine dose, and ketamine dose will be the same for both sessions.
Subjects will not be told what the exact ketamine dose they will receive, but it will be based on their weight and will be no higher than 0.08 mg/kg.
