The goal of this project is to study the contribution of the dual-nostril configuration in olfaction. In othermammalian sensory systems, vision and audition, the use of dual-sensors, two eyes and two earsrespectively, adds dimensionality to perception. For example, inter-ocular comparisons allow for depthperception and inter-aural comparisons allows for sound source localization. We will conduct a series ofpsychophysical and fMRI studies aimed at elucidating the differences between the sensors and themechanisms of bilateral signal integration.
