Number of studies report that even when experimental animals are subjected to the exact same conditions, they differ in their behaviour. If these differences were stable in time and across several experimental procedures, we could talk about personality. This diploma thesis studies inter-individual differences in behaviour of laboratory rats (Long Evans strain) in a series of experiments conducted in early ontogeny and in adult age. Apart from analysing inter-individual differences in behaviour and personality of experimental animals, this thesis has two main aims. The first aim is assessing stability of inter-individual differences in behaviour throughout ontogeny. The second aim is to explore possible link between inter-individual differences in behaviour and performance in cognitive tests. We confirmed the existence of inter-individual difference in behaviour in laboratory rats. In this thesis we were, however, not able to assess personality of experimental animals. The differences in behaviour were best described by behaviour in Open field test and Elevated plus maze test. Our results also show marked differences between successive trials of these experiments. We also report that performance in Active allothetic place avoidance is not linked to performance in Morris water maze, even though both...
