The Affective Neuroscience Lab in the Department of Psychology at Vanderbilt University is currently recruiting healthy male adults, 50–65 years old, for a multiday study that attempts to understand the relation between brain chemistry and decision-making. The study involves tests of thinking ability and personality, as well as brain imaging.

You may be eligible if you are a healthy male adult who:

  • Is right-handed
  • Is not taking medication that impacts attention or mood
  • Has no history of psychostimulant use (such as amphetamine or Ritalin)
  • Is not a current tobacco or nicotine user
  • Does not have high blood pressure and is not being treated for high blood pressure
  • Has no history of major psychiatric illness (such as any mood disorder, psychotic disorder, substance use disorder or eating disorder)

Before scanning, participants will undergo a thorough medical and psychiatric assessment to ensure they qualify for the study. The assessment includes a physical exam, EKG, urine analysis, measures of blood chemistries (blood sample), and a urine drug screen. Participants may be excluded at any point in the study based on results of these examinations.

The entire study takes approximately 24 hours in total over multiple sessions. Participants will be compensated for their time.

If you are interested in hearing more information and possibly participating, please contact Danica San Juan or Leah Burgess, research analysts, at (615) 343-1446.
