| Abstract: | This paper reviews the current work on mouse genetics, brain, and behaviour in my laboratory. It starts with an historical account of our research and shows how certain research themes, such as olfaction, learning, social behaviour, and environmental effects in rodents have led to our current research on behavioural phenotyping of inbred, mutant, knockout, and transgenic mice. We are concerned with finding neural and behavioural sequelae to genetic manipulations in mice and use a battery of tests to detect behaviours that are altered in genetically modified mice. In this way we are working to dissociate neural and behavioural effects of different gene manipulations in mouse models of neurodegenerative diseases. Sensory, motor, cognitive, affective, and social behaviours may all be affected by gene manipulation, thus careful behavioural techniques, with attention to the mice themselves, the apparatus, and procedure, experimenter variables, and environmental effects are necessary in order to determine a reliable and valid mouse behavioural phenotype. As both the genome and the environment have significant effects on the behavioural phenotype, our future research will utilize an epigenetic approach to examine how environmental cues modulate gene expression in the behavioural phenotyping of transgenic mice. |
