| Research Abstract |
Relationships between NO-production and the excitation mechanisms in the taste cells and between the taste sensation and appetite regulation were investigated. NO-sensitive guanylyl cyclase (sGC) was detected and suggested to participate in the signal transduction pathways in the sugar cells, while other pathway was detected in the bitterness cells. Meanwhile it was demonstrated that the fly's aversive behavior to sucrose after their feeding sucrose in the limonene fume was due to the formation of long-term memory.
