The Vibration module (02VP) provides of a vibration sensor pad which can be placed on the bottom of the homecage to indirectly monitor sleep in a noninvasive manner, or placed as a cieling.
Using the vibration sensor, total sleep/inactive state can be continuously recorded up to several weeks, with data automatically analyzed. Any tremors and generalized seizures will be recorded for later manually scoring.
The Piezo-pad can also be used for the Tail suspension test as a measure of depression. The pad is placed on the top of chamber as a ceiling. The tail of the test mouse is taped to the Vibration-pad, so that the mouse is suspended around 20 cm above the homecage floor. Total inactive time indicated by immobility during the 6-min test period is automatically recorded and calculated.
