Research Abstract

It has been revealed that gustatory informations for five taste modalities are mediated by distinct taste bud cell populations in peripheral. However, it remains unknown that the coding mechanisms including neural pathways transducing such informations and information processing in the central nervous system. To elucidate these matters, novel trans-synaptic tracer transgenes were developed in this study. These developed tracer transgenes enabled the visualization of neural circuits originating from two distinct cell populations and the analysis on the correlation between these circuits. The correlation between the neural circuits originate from two populations of taste receptor cells were revealed in this study.
