avoid bright light exposure is the basis for The Barnes Maze behavioral test. \u00a0Mice also abhor swimming which is the basis for the classic Morris Water Maze cognitive memory task. \u00a0The goal of the Radial Water Tread Maze is to pair the aversive qualities of both tasks in a paradigm that minimizes interpretive difficulties. \u00a0In this new task, the mice are introduced to a 30 inch galvanized, circular tub with nine holes cut in the side at regular intervals. \u00a0Eight of the holes are decoys which lead to dead ends. \u00a0One of the holes leads to a dark, escape \u201csafe box\u201d hosting a comforting heating pad. \u00a0\u00a0All holes extend outward similar distances before either terminating, or bending at a 90 degree angle to prevent direct visual determination of the actual escape route. \u00a0To provide the escape incentives of the Barnes and Morris Mazes, the tub is filled with ~ 1 inch of water and a bright light is positioned directly over the entire apparatus.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A mouse is introduced to the center of the maze containing unique visual images and objects along its side functioning as spatial cues for the animal. \u00a0The mouse is then required to find the escape route from the enclosure. \u00a0Three metrics are used in this task: latency to escape, number of errors, and distance traveled to reach the escape hole. \u00a0Once the animal finds the escape route, it is allowed to remain in the heated safe box for one minute prior to engaging the next training trail. \u00a0An animal is given three trails per training day, and the testing period can be run across successive days to test long term memory acquisition. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">A typical experiment employs a four-day training period before a test on the fifth day. \u00a0The animal is allowed to search for the correct escape hole for a 3 minute period, after which the animal is guided gently to the correct escape route by hand.<\/span><\/p>\n<p><b>Options<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A long-term memory test conducted one, to several weeks, after the initial training
