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 measure 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.

  • Simultaneous operation of up to 4 test boxes
  • Rat-only, mouse-only and combination systems
  • Software-controlled light, shock, tactile (air puff) and auditory stimuli (sine sound up to 20 kHz)
  • Light-beam frames with variable distances
  • Optional application of WAV files for acoustic discrimination
  • Optional extension for Learned Helplessness testing
  • Optional Passive Avoidance conversion set
