Technology Overview

Gramophone is a single-dimension locomotion tracking device. It consists of a rotating disk, an electric registration system, a stabilized head holder and a monitor. 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 is registered by software-controlled manner. The behavior response and the two-photon Ca2+ signals can be recorded simultaneously and aligned to each other.


  • spinning speed recording with 3 ms temporal resolution

  • data digitalization with ~1500 data points per rotation in the free run mode

  • 16 ms temporal resolution in the full behavior mode

  • control and analysis in the Femtonics microscope control software

  • two-point head holder with adjustable height


  • 8 different built-in image patterns with adjustable RGB color

  • custom mazes and behavior rules can be designed with minimal programming knowledge

  • velocity or displacement rules can be easily applied

  • the system can handle two monitors simultaneously, providing a corridor-like arrangement

  • stabilized head holder keeps the skull stable during moving
