Response Wheel

This response device was patterned after a design by Dr. Conan Kornetsky, Boston University. It consists of a 2.75" (7.0 cm) wide wheel 2.75" (7.0 cm) in diameter formed by twenty stainless steel rods placed around the circumference. The wheel is easily turned by a test animal to produce a switch closure for every 90 degrees of rotation. This device is particularly useful in Intracranial Self Stimulation studies or any time motor performance may be impaired.

The width of the wheel is approximately 1.5" (3.8 cm) and is mounted on a modular panel that is 2.355" (6.0 cm) wide. This wheel has been modeled after the standard rat wheel proportioned for the mouse and incorporating a resistance free photobeam detector in place of a micro switch to record a response for every 90 degrees of rotation. The outside diameter of the wheel is 2.25" (5.7 cm) with twenty 0.094" (2.4 mm) diameter rods placed on a 2.0" (5.1 cm) diameter circle.

The width of the wheel is approximately 0.75" (1.9 cm) and is mounted on a modular panel that is 1.688" (4.3 cm) wide. This wheel has been modeled after the standard rat wheel proportioned for the mouse and incorporating a resistance free photobeam detector in place of a micro switch to record a response for every 90 degrees of rotation. The outside diameter of the wheel is 2.25" (5.7 cm) with twenty 0.094" (2.4 mm) diameter rods placed on a 2.0" (5.1 cm) diameter circle.
