| Research Abstract |
Functional laterality of the brain is widely observed in the animal kingdom. The terrestrial mollusk Limax has an ability to acquire associative olfactory memory, and this ability is dependent on a part of the brain, procerebrum, that is equipped bilaterally in the brain. A previous report by other group suggested that only the unilateral procerebrum is used for the mnemonic function, but there was no evidence based on a behavioral study. By means of surgical brain ablation in combination with the behavioral study, we have demonstrated that (1) either right or left procerebrum is randomly used, (2) the memory is stored in a unilateral procerebrum, and (3) there is no memory transfer from one procerebrum to the other.
