A device for the study of the sleep disturbances in laboratory animals

摘要

A device includes, in combination, a horizontal circular support plate (1) for animals (2), driven in rotation about a vertical axis (3), a cylindrical wall (4) the outside diameter of which is substantially equal to that of the rotary plate (1), this wall delimiting an internal confinement space (7) forming a cage for housing the animals moving freely on the plate, a fixed intermediate partition (12), extending inside the cylindrical wall (4) dividing the internal confinement space into two opposite compartments (13, 14), an upper closing lid (15), preferably removable, integral with the intermediate partition (12) and extending parallel to the plate (1), and a system (36) for the supply of a respiratory gas through the closing lid (15) for the animals (2) present in the two opposite compartments (13, 14) of the confinement space (7).
