Current conditioned place preference testing procedures expose test subjects to various stimuli to measure their motivational effects. The test subjects are imaged using MRI to delineate various regions of the brain that are affected by the stimuli. This project developed MRI head restraints; created CAD models of them, and 3D printed them using 3D printers and verified their effectiveness. The project built an odor testing chamber with three unique compartments. Ventilation was designed to keep two odors in separate compartments. The middle section of the test facility was the neutral zone that the test subject enters initially. The flow characteristics in all sections was analyzed and documented to ensure that odors presented in either chamber did not drift into other chambers.
