Rota Rod lets users test effects of drugs, brain damage, or diseases on motor coordination or fatigue resistance in rodents. After animal is placed in rotating lane and timer is started, unit automatically records latency to fall (minutes and seconds) and rotational speed. Rotation can be electronically set at constant 4–40 rpm, or alternatively accelerating rate may be selected at defined time (30 sec to 10 min in 1 sec increments). Acquired data is saved in table form by lanes/trials.
