Decision-Making Study
We are currently recruiting healthy adults between the ages of 50-85 for a multi-day study of the relation between brain chemistry and decision making. The study involves tests of cognitive (thinking) ability, personality tests, and brain imaging including magnetic resonance imaging (MRI) and a positron emission tomography (PET) scan.
Only individuals who are currently healthy, are not taking medications that impact attention or mood, do not have history of using psychostimulants, and are not current tobacco or nicotine users may participate. Women who are pregnant, lactating, or trying to get pregnant cannot participate.
The entire study takes approximately 18 hours total, spread out over 4-6 visits. Participants who complete the study will be compensated for their time.
