Description 1/8″ thick-walled acrylic tube Tube measures 8″ Diameter x 12″ Height The Cylinder Test The cylinder test involves placing the animal into a transparent Perspex cylinder ∼8″ in diameter and ~12″ high (sufficient to allow free rearing and turning but to avoid the animal climbing out). An angled mirror is placed behind the cylinder to observe the animal’s movements at all angles. Typically, the rat is placed into the cylinder. Have movements video recorded for a fixed period, say 5 minutes, for subsequent analysis in terms of the number and duration of rears, number, and duration of left and right paw contact with the wall surface, and whether the animal uses one or both paws for weight bearing when it descends from rearing.
