Triadic Wheel Turn Package

This triadic design has been used for over 30 years to study the impact of stress controllability on a variety of behavioral as well as physiological indices (Current Protocols in Neuroscience, Feb 2001, Supplement 14).

  • Designed to run three animals at the same time. Subjects in the “escape” condition learn to turn the response wheel to terminate the aversive stimulus for themselves and a “yoked” partner. The “control” subject is not stimulated.
    • Escape (controllable aversive stimulation)
    • Yoked (uncontrollable aversive stimulation)
    • Yoked (no aversive stimulation)
  • Each of the three wheel turn chambers is housed in its own sound isolation cubicle for optimal acoustic, visual, and olfactory isolation between subjects
  • Extending out the back of each chamber is a tail holder with curved aversive stimulation electrodes, and a soft velcro strap to hold the tail in place
  • Chambers can be easily removed for cleaning

NOTE: Aversive stimulators, a Med-PC® interface package, and software must be ordered separately. The programming flexibility of Med-PC® software permits any programmed contingency across animals.
