Shuttle Avoidance Instrument




Step through passive avoidance testing capitalizes upon a mouse’s preference for dark enclosed spaces. This method consists of a mouse being confined in a small, brightly lit compartment. After a brief confinement, a door leading to an adjoining darkened compartment is opened allowing the animal to escape from the illuminated section of the apparatus. Once inside the darkened arena, it receives a brief stimulation. A mouse that recalls that it was shocked in the darkened arena and that can inhibit its desire to enter the dark will increase the latency to enter the dark. The longer latency and refusal to enter the dark is measured that is commonly used to study mouse learning and memory.


The SINGA Step through System PA-02 is consists of a controller and a test station for the passive avoidance task in mice. The station features a lit and a dark compartment divided by a sliding door. The floor grid is delivered an electric stimulation while the animal crosses through a small opening into the dark compartment. The infrared sensors allow quick and ongoing detecting of animal location that is reliable taking down the response latency. Latency to pass through the door is recorded in 0.01second increments.


The removable excretion box attached gives the station a good clean. The data stored in the internal memory, can be printed out in real time printer (optional) or routed to computer via the optional software (optional).
