Abstract

The invention provides an active unwinding device for observing freely moving animals and an unwinding method. The unwinding device comprises a test frame, a top plate, a bottom plate, a stepping motor, a driving assembly, a data collector, a sensing device, a conductive slip ring, a support frame, a connecting rod and a controller. The bottom plate and the top plate are fixed at two ends of the test frame, the output end of the stepping motor penetrates through the top plate, and the conductive slip ring rotor penetrates through the top plate. The driving gear is mounted at the output end of the stepping motor; the driven gear is meshed with the driving gear; the driven gear is connected to a rotor of the conductive slip ring on the lower surface of the top plate. One end of the supporting frame is connected to the driven gear, and the other end is connected with the data collector. One end of the connecting rod is connected to the driven gear, and the other end is connected with the sensing device. The controller is fixedly installed on the upper surface of the top plate. According to the invention, the connecting line which is wound / twisted in the experiment process of free movement of the mouse can be automatically unwound.

Description

technical field [0001] The invention relates to the technical field of automatic control untwisting, in particular to an active untwisting device and untwisting method for observing freely moving animals. Background technique [0002] Microfluorescence microscopy is a technique for fluorescence imaging of neuronal population activity in freely moving small animals, which has made important contributions to the development of neuroscience. By attaching a miniaturized microscope to the head, the microscope can image the activity of up to hundreds of neurons in its field of view in real time as the small animal moves freely. The head-mounted device transmits the signal through the transmission cable, but the cable will be entangled / torsioned during the free movement of the mouse, which restricts the free movement of the mouse, affects the observation results, and brings a lot of inconvenience. Contents of the invention [0003] In view of the problems existing in the existin...
