Mice were singly housed on sawdust in standard Makrolon type II cages enriched with cardboard nesting material for at least one week prior to experiments, with water and food ad libitum (7:00/19:00 lights on/off; providing an abrupt phase transition).

Open field
Mice were introduced into a corner of a white square open field (50 x 50 cm, walls 35 cm high) illuminated with a single white fluorescent light bulb from above (200 lx) and exploration was tracked for 60 min (Viewer 2, BIOBSERVE GmbH, Bonn, Germany). The surface area was divided into nine equally sized squares, and the center square was used as center area. Zone visits to the center area were counted using the body reference point. To counteract the detection of distance moved due to jitter of body reference point produced by grainy video signal, track correction option was set to 1.
