title: A device for jointless connections with unrestrained animals.
abstract: An apparatus is described allowing multichannel connection with unrestrained animals without using joints. The twisting of the connection lines caused by the rotation of the animal in its cage is detected by means of a torsion wire connected to an electronic device. This provokes a temporized rotation of the bottom of the cage in the opposite direction in order to untwist the lines.
