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.
Scavenging machines are used in the collection and removal of waste anesthetic gases (WAGs) vented during the anesthetization processes. These systems comprise collection devices, interfaces, and disposal systems. Scavenging machines also help monitor the gases and prevent barotrauma to the subject resulting from a change in incoming and outgoing gas flow.
