A Behavioral Comparison Of Four Inbred Strains Of Mice, Erin Wood

Theses and Dissertations

Isogenic, or inbred, mouse strains are currently the experimental subjects of choice in laboratory studies focused on genetics, pharmacology, and psychological issues. Understanding phenotypic differences in isogenic strains is important in order to interpret experimental results obtained from inbred mouse strains. Four commonly used inbred strains, C57BL/6NHsd (C57), DBA/2NHsd (DBA), 129S2/SvHsd (129), and Balb/cAnHsd (Balb/c), are investigated in this study using four different behavioral tasks that measure locomotor activity and cognitive behavior (Morris Water Maze (MWM), T-maze, and operant autoshaping procedures). In the locomotor activity task 129 mice showed significantly less horizontal ambulation than any other strain, while differences in …
