Active Avoidance / Passive Avoidance

The TSE Active Avoidance system is a fully computerized avoidance conditioning system. A variety of compartment dividers incl. electrified hurdles are available. Light-beam frames with variable distances for several species monitor the animal's movements and location.

A user-friendly Windows software allows to adjust several parameters including habituation, time to shock, shock length, maximum duration and inter-stimulus interval and shock parameters. The resulting data table lists for example conditioned, unconditioned and inter-stimulus transfers and mean reaction times. Distance traveled is presented as a measure of locomotor activity.

The Active Avoidance paradigm is also an integral part of the highly flexible Multi Conditioning System.
