| Summary: | The main objective of this thesis was to test different aspects that might influence the ability of spatial orientation of leopard gecko (Eublepharis macularius) in Morris water maze (MWM). This group of animals has already been tested once before (thesis Voňavková, 2013). After a few intervals (two & four months break) this test of allothetic orientation was repeated. Repetition of the test is necessary to verify whether there are evidence of a learned spatial orientation within the long-term memory or not (extinction of spatial information). The main objective of this thesis is to find out whether the animals are able to remember the orientation marks from the training after a several-months break, or if they will have to learn the task again from the beginning. In 18 % of tested geckos the track has been gradually shortened, but the time of finding goal-location (platform) remained the same. In 43 % of animals the time necessary to reach platform got worse, but the lenght of the track remained the same. Thus, animals remembered where the platform is located, but their motivation to reach it was much lower than at a firts few sessions. Another objective was to verify whether gecos are even able to compensate the active and pasive body movement by their head, keep the grafic marks on the arena in...
