This MSc. thesis deals with dissecting the link between memory, genetics, and metabolic syndrome. Memory is a very complex behavioral trait, probably influenced by innumerable factors. For this experiment HXB/BXH rat recombinant inbred lines (n= 30) and their parental strains (n=2) were used to be trained in the hippocampus dependant spatial learning task called Allothetic Active Place Avoidance. Rats were to memorize sector of a rotating circular arena, which they were to avoid, being motivated by receiving an electric shock upon entering the forbidden sector (4 training sessions; shock sector on the North, 1 retrieval session (no shock), and 3 reversal sessions, to-be-avoided sector facing South; each session 20-min long, retrieval 10-min). Control experiments to exclude impact of motor or sensory abnormalities were run in a form of open-field test and beam-walking test. Correlation with metabolic phenotypes was conducted in an online database of known HXB/BXH phenotypes (GeneNetwork.org). The results showed that differences in learning were significant between the groups (p<0.05); correlation analysis indicated no putative link between selected traits related to metabolic syndrome and memory in rats. The genetic analysis showed a suggestive locus on chromosome 20 for a learning parameter, and...
