Gramophone system for velocity recording

from Femtonics

Femtonics Gramophone is a behavior studying system which enables head-fixed but free-to-move rodents to run on a disk.
Lead time:
Max. 6 weeks

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.

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:
Gramophone skeleton
Spare disk
Stabilized head holder
Set of 10 head-plates
Packaging

Features
  • 14400 counts/rotation angular resolution
  • Up to 500 Hz sampling frequency
  • Robust and durable construction
  • Easily removable and cleanable running surface
  • Easily adjustable head fixation for in vivo imaging and electrophysiology
  • Programmable inputs and outputs
  • Open-source Python 3 software for recording locomotion and conditioning mice
Benefits
  • Flexible usability: mobile, compact system for behavioral training, locomotion measurements, microscopic imaging, electrophysiological studies, etc.
  • Easily integratable to your own system
  • A two-point head holder with adjustable height fixes the rodent’s head, keeping the skull stable during moving
  • Spinning speed is recorded with ~3 ms temporal resolution, and it is digitalized with ~1500 data points per rotation
  • Velocity traces are saved in .csv format which can be imported to MES with Behavior Importer Modul or to other third-party programs with precise timing
  • Three TTL output channels with 3.3V logic can be controlled by the system during complex behavior protocol, one analog input channel can be recorded with 10-bit resolution
