Overview: Effect sizes (Cohen d) for 16 behaviour variables

Mutant mice showed medium overall behavioural difference from wildtypes, with nine of 16 behaviour variables significantly impacted in these mutant mice. In the elevated plus maze task, four behavioural variables of five were significantly impacted in mutants. In the open field/novel object exploration task, one behavioural variable, OF NOE total distance, was significantly increased in mutants. In the rotarod task, one behavioural variable, RR naive fall time, was significantly decreased in mutants. In the fear learning task, two behavioural variables of two were significantly impacted in mutants. In the contextual memory task, one behavioural variable, contextual memory mean, was significantly decreased in mutants. Only cued memory was unaffected. Definitions of variables may be found below.

The G2CMine data warehouse provides cohort summaries and individual mouse observations from the Kras knock-out line phenotyping.
