Development of an affordable system for olfactory stimulation during brain functional magnetic resonance imaging 1: Unit of Biophysics and Bioengineering, Faculty of Medicine, University of Barcelona, Barcelona, Spain; 2: Clinic Institute of Gynecology, Obstetrics and Neonatology, Hospital Clínic of Barcelona, Barcelona, Spain; 3: Institut Investigacions Biomediques August Pi Sunyer, Barcelona, Spain; 4: Magnetic Resonance Imaging Core Facility, IDIBAPS, Barcelona, Spain; 5: CIBER of Respiratory Diseases (CIBERES), Madrid, Spain Functional magnetic resonance imaging (fMRI) is a technique to map the activation of different brain areas and thus to track the neural response to specific external stimuli, including those elicited through the olfactory system. Widely extending fMRI applications to study the neural pathways in olfactory function has been partially hindered by the technical complexity of designing a device to apply controlled odors specifically to patients subjected to fMRI. Most commercial devices are either complex, expensive, with slow response time or require an external pressurized air source. To facilitate biomedical research on and clinical assessment of the neural pathways modulated by the olfactory system, we have developed and tested a simple, low-cost, open source, stand-alone device allowing to apply easily selectable controlled sequences of olfactory stimuli in subjects undergoing fMRI. | |
