Overview of the mouse presence probability on the EPM over a 5 minute period. Each graph represents for each gender in a specific genetic background, where on the maze the mice are present most. Increased presence is indicated in red, whereas blue reflects a lower probability to find the mouse in that area. The X-axis and Y-axis illustrate the superposition of the two open and closed arms respectively. The sharp mouse contour in the middle of the open arm in graph A and at the end of the open arm in graph C illustrates that one mouse resided there for a long period. This mouse is considered an outlier, since it does not represent the rest of that mouse population. Since this graph is a superposition of each population, a more representative sample would be indicated by more blurry edges.
