The AutoSomTM system is an automated sleep-deprivation system specially designed to conduct sleep-related research in rodents. The system enables non-invasive, fully automated, and highly-regulated monitoring of rodent’s sleep/wake activity.
The device consists of a floor-sensor board that detects the vibrations when the mouse moves in its home-cage. A motor is fixed under the floor-sensor board that turns the rotating bar to keep the animal awake.
The system operates four units interfacing one computer via USB cable. The screenshots of the system using a vibration signal that is used to assess active or inactive (‘sleep’), and an infrared array is utilized for the detection of location and locomotion of the animal.
The Y maze is similar to the T maze, except with three arms at 120 degrees to each other. The rodent or mouse starts at the end of one arm, then chooses between the other two. Spontaneous alternation is measured to demonstrate learning.
The Y-maze is often preferred to the T-maze because gradual turns decrease learning time as compared to the sharp turns of the T-maze. It is also a smaller maze* to allow fewer degrees of freedom of movement, focusing the animal on the task at hand. The Y Maze can also be baited with food for rewarded alternation. Food wells are standard 1cm deep.
