A new device for behavioral analysis on rats exposed to high pressure.
The high pressure nervous syndrome (HPNS) is the term applied to the disturbances which appear when humans or animals are exposed to high pressure. The principal behavioral symptoms include locomotor activity, tremor and myoclonia. These symptoms have often been visually estimated previously, on free-moving animals, only by their onset pressure. In the present study, we report on the use of a new computerized device which enables a quantitative analysis of the behavioral symptoms of HPNS. These disturbances could be essentially dependent on the variations of pressure. This new device could also be profitably employed for other behavioral studies.
