This video shows how to use the Barnes Maze with a mouse. The Barnes Maze testing procedure is used by researchers to assess spatial learning and memory in laboratory animals following repeated trials.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Basic Housing of Mice House the mice in plastic cages with solid bottoms and sides, and a layer of soft bedding and nesting material such as paper shredding. Use bedding that is composed of shredded corn cobs or wood shavings, and ensure that the bedding is changed regularly for sanitation. Provide access to f…
