| Outline of Final Research Achievements |
C. elegans changes the behavior through learning of salt concentrations. In addition, depending on whether they were fed or starved when they experienced salt, they switch the behavior from attraction to avoidance. In this study, the mechanisms for learning-dependent changes of behavior were investigated at the levels of molecules, neural circuit and behavioral regulation. As a result, previous questions were solved in the mechanisms of changes of neurotransmission caused by salt and food experiences, information flow in the neural circuits, and behavioral mechanisms of chemotaxis, leading to a comprehensive understanding of the behavioral switch.
