Sleep deprivation impairs spatial, emotional, and working memories, and augments anxiety-like behaviors.
The walking model of sleep deprivation apparatus from MazeEngineers is an automated device that provides movement at researcher programmed intervals to prevent REM sleep. This model prevents sleep using a sweeping bar at the bottom of the chamber.
Safe to use for up to 8 rodents, food and water apparatuses are available to allow long-term experimentation. Please note that this is one of two possible sleep deprivation models, the other being the chamber sleep deprivation apparatus

Apparatus and Equipment
The Sleep Deprivation Chamber consists of a rectangular plexiglass cage. A sweeping bar is present at the base of the cage that can be controlled by software to allow the desired speed to move to disturb the subjects’ sleep as the bar touches their feet.
Sleep is essential for the normal functioning of humans. The lack of sleep causes cognitive deficits in waking cognitive functions, observed as the inability to focus, think with clarity, and sustain attention (Worley, 2018). Sleep deficits also have adverse outcomes in children, affecting their cognitive, physical, and socioemotional development (Schlieber & Han, 2021). Therefore, sleep deprivation and sleep fragmentation studies can examine how sleep deficits affect different domains in human cognition and behavior. The Sleep Deprivation Chamber can easily be used to study the effects of sleep deprivation on cognition and behavior using a rodent animal model. It can be used in conjunction with other behavioral testing apparatuses such as the Y-Maze and the Morris Water Maze.
The Sleep Deprivation Chamber also includes built-in food and water systems for long-term experimentation. The chamber is large enough to accommodate multiple subjects to prevent social isolation stress and disrupt the sleep of several subjects simultaneously.
