Internal and external factors which modify the innate behaviour of the mouse in the double Y maze.
A test to study an innate behaviour of mice was standardized and the factors which could modify the results were examined. A track left by a mouse had effect upon the choices of the next one, the homogeneity of light at the exits was important, whereas orientations of the maze were not relevant and finally the significance of the test was increased when a maze with floating single-directional doors was used.
