The looming is a behavioral test allowing to study freeze or flight responses of animals after the predator appearance.
On rodents, the sight of a predator may induce 2 types of behavioral responses: freezing and/or flight. The looming has been developed to mimic different threatening situations for animals and thus to study these responses.
The looming includes:
An experimental chamber, dimensions: L 480 x l 300 x h 200 mm,
A screen located above the cage that projected the “predator”,
One or more refuges that can be positioned in the middle or on sides of the cage
A computer with POLY_LOOMING software to manage the experiment and POLY_Files to extract the results,
An electronic interface,
A floor with infrared backlight.
