Ugo Basile Active Avoidance (Shuttle-Box) Apparatus for Mice and Rats
Number of Avoidances (the mouse crossing to the other compartment during the warning signal)
Number of non-responses (the mouse failing to cross to the other compartment during the trial)
Response latency (latency to avoid or escape)
Number of intertrial responses (crossing the barrier within the intertrial interval)
Testing is conducted in a two chamber cage, sectioned by a partition with an intercommunicating opening at floor level. Both compartments are lighted by overhead stimulus lights. Each compartment is equipped with a grid floor which delivers the foot shock. The tilting floor ensures reliable detection of movement across the two compartments.
