We studied the effects of -irradiation on the salt chemotaxis learning of , that is well known as a model organism for the nervous system. As a result, we found that chemotaxis to NaCl immediately after irradiation was significantly decreased only during the salt chemotaxis learning. In addition, the radiation-induced resoponse is significantly suppressed in the mutant. These results suggested that the effects of ionizing radiation on the salt chemotaxis learning behavior of mediated through GPC-1 localized in the specific sensory neurons.
