Popis:	We have recently demonstrated that preceding motor activity can facilitate decision-making not only in humans and mammals but also in molluscs. In the behavioral paradigm used, snails Lymnaea stagnalis were removed from their natural environment (water) and placed in a dry, asymmetrically lit arena from which they had to decide which way to go in order to reach an aquatic environment. One possible explanation of the observed effects of preceding motor activity was that it could affect the snail's memory of light conditions that corresponded to its previous aquatic habitat. Here we report experimental results discarding this hypothesis. We suggest that preceding intense locomotion is likely to facilitate decision-making by increasing the level of confidence.
