Treating neurological issues requires an understanding of brain mechanisms which may be studied using functional neuroimaging of awake animal test subjects. The purpose of this project was to aid in this research by developing a system that could reliably and semi-quantitatively deliver airborne stimuli to test subjects undergoing MRI regimes. Up to 4 stimuli were reliably delivered through use of a compressor, tank, flow meter, pressure regulator, and solenoid valves, and odor strengths were adjusted by altering flow rates. After delivery, odorants were evacuated through a separate outlet, filtered, and released outside the MRI room. Future uses for the device include research into addiction and fear mitigation as well as commercial uses such as scent marketing and virtual reality.
