Gramophone complete system
Gramophone is a single-dimension locomotion tracking device. It allows a head restrained mouse to run on the disk and to respond to visual or other stimuli. The speed and the direction of the running are registered by software-controlled manner.
The monitor shows visual stimuli such as predefined patterns or customizable linear mazes that change in accordance with the mouse’s
movement on the rotating disk, creating a virtual reality where the animal can navigate itself by moving the disk. It can be used for high accuracy velocity recording in conjunction with a two-photon microscope, or as a control interface for behavioral training in a virtual linear maze. The behavior response and the two-photon Ca2+ signals can be recorded simultaneously and aligned with each other. The Gramophone can be coupled with multiple operant devices such as a water reward, air puff, etc., and the spinning speed of the disk is recorded in a triggered manner.
Kit contains:
Laptop
Monitor
Gramophone kit with velocity recording: Gramophone skeleton; Spare disk; Stabilized head holder; Set of 10 head-plates; Packaging
Features
- 14400 counts/rotation angular resolution
