Why mice develop 'knots' while exploring a new environment

During exploration of a new environment, mice establish 'knots' - preferred places visited sporadically and marked by the performance of twists and turns, according to a new study by Israel and Canada-based researchers. The research provides evidence that the formation of these places is increased by stress, and suggests that the tortuous movements improve the interpretation of the visual scene, enhance the memory of the place and provide the mouse with multiple views that turn the established places into navigational landmarks.
