Both flies and mice were recorded using a digital camera above a rectangular arena in which 4 animals could freely interact. Flies interacted in a plexiglass arena with sloped walls and a low glass ceiling to ascertain an upright position and visibility during the 10 min recordings in the light phase (A). Mice interacted in a plastic arena, with multiple nests attached to it and ad-libitum access to food and water (B). The ceiling consisted of transparent plexiglass to ensure visibility. Data from both the RFID-receiver, below the arena, and the digital camera were collected, stored and combined in the attached computer. Recordings of mice behavior were conducted around the clock for 6 days, in both the light and dark phase.
