| Outline of Final Research Achievements |
To visualize central neurons responsible for taste perception, we made transgenic animals expressing thermo-sensitive TRP ion channel (dTRPA) in taste cells. Heat stimulation of the sweet- and bitter-cells induced different patterns of ERK phosphorylation in the subesophageal ganglion. In addition, we tried to identify the neurons controlling feeding behavior using enhancer trap lines expressing sodium channel in a subset of neurons in the brain. We found that excitability of subset of dopaminergic neurons modulates the feeding behavior.
