Gemini - Data Sheet

The GEMINI Avoidance System is purposely designed for active and passive avoidance and learned helplessness testing in both rats and mice. GEMINI is available in two configurations: Shock or Shock and Airstim. On the Shock model, shock is used for the Unconditioned Stimulus. On the Shock and Airstim model, the user can choose shock or air puff for the Unconditioned Stimulus. Shock uses a scrambled delivery to the rods of the floor preventing the animal from discerning a pattern. The Air Puff is delivered through tubes with multiple outlets spanning the length of each compartment. The tubes are mounted both in the front and back of the compartment. The animal will receive the air puff from both sides. Conversion from rats to mice or mice to rats is possible in less than five minutes. GEMINI provides maximum flexibility in test paradigms by allowing the use of one or more stimuli simultaneously. A key feature is the very silent center Auto-Door which will not induce unwanted behaviors. It also lowers by gravity alone so no animal can be injured.
