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:
It is also possible to record electrophysiological activities of neurons in rodents by connecting one the animal to our 64-channel electric commutator. In this way, this system can synchronize neuronal and behavioral events; and also sequences of appearance of the predator.
Our POLY_LOOMING software allows to:
Our POLY_Files software calculates:
