Our research interests substances by using sensory functions of taste and smell. Our research interests center on the mechanisms and center on the mechanisms and functions of the sensory cells for these functions of the sensory cells for these chemical senses. chemical senses. Chemical sensory cells can transduce chemical Chemical sensory cells can transduce chemical stimuli into electrical responses of their plasma membranes. These stimuli into electrical responses of their plasma membranes. These transduction machineries are very important for the first cell transduction machineries are very important for the first cell events events of taste and smell sensations. To study their of taste and smell sensations. To study their transduction transduction mechanisms, we record and analyze electrical responses of taste receptor cells and olfactory receptor mechanisms, we record and analyze electrical responses of taste cells of vertebrates by using patch-clamp techniques and receptor cells and olfactory receptor cells of vertebrates by using other electrical recording methods. We are also interested in ion channel functions of these chemical sensory cells.patch-clamp techniques and other electrical recording methods.
