Detecting Synaptogenesis induced by Ketamine and Motor Learning – Recruitment

We are conducting a brain imaging study to look at the brain’s ability to form new connections following 1) ketamine administration, and 2) learning of new motor skills.  

We are looking for right-handed healthy male volunteers 25 to 60 years of age to take part in the study.  

If you take part in the study, you will be expected to:   

  • Attend the Invicro imaging centre and/or the CIPPRes clinic (CNWL)  
  • Imperial Psychopharmacology and Psychedelic Research clinic) at St.  
  • Charles Hospital on 5 or 6 occasions  
  • Provide some blood samples.  
  • Have your left hand bound by bandages for up to 24 hours.  
  • Receive an intravenous (potentially high) dose of ketamine.  
  • Complete questionnaires about yourself.  
  • Receive a total of 4 (radioactive and magnetic*) brain scans across two visits.  

*Two combined positron emission tomography/magnetic resonance imaging (PET/MRI) scans and two separate MRI scans.  

If you are suitable, and chose to participate in the study, we will reimburse you for your expenses, your time and any inconvenience (£450, plus travel expenses).  

If you are interested in taking part, please contact or on the following number (07415 332693).
