Mouse Feeding Monitor

Measure feeding behavior

The Mouse Feeding Monitor (MFM) is a lowcost, easy-to-clean, and reliable solution designed to monitor the interaction of a mouse with a stainless steel feeder. In this case the MFM can register feeding duration and frequency. 

Designed for PhenoTyper

The MFM has a modular design, allowing you to easily attach it to a standard PhenoTyper® mouse cage. You can simply slide it in the position of the stainless steel feeder that is delivered with every cage, effectively placing it between the feeder and the wall. There it registers any interaction with the food hopper mounted on the other side.

No outside IR interference

The MFM uses a straight-forward beam break mechanism. When the mouse reaches for the food in the stainless steel feeder it interrupts the IR beam. This IR beam is pulsating at a frequency of 38kHz; this ensures that outside IR sources cannot interfere with its operation.  

Connected to the Trial & Hardware Control Module

Connected to EthoVision® XT Trial & Hardware Control, you can collect the data from the MFM and incorporate this with your tracking data. Data from the MFM is collected by the IR Beam Controller, and then sent to the computer running EthoVision XT via the Noldus USB IO-box. You can connect up to two Feeding Monitors to one IR Beam Controller.

More than a simple beam break

The input that EthoVision XT collects from the MIM can also be used in complex Trial & Hardware Control protocols. This transforms an otherwise passive feeding monitor into a nose-poke device that can trigger other devices or events in complex operant conditioning tasks. Furthermore, the device fits any kind of arena with the same feeder design as the PT3000. 

Why use the Mouse Feeding Monitor

  • A cost-effective and reliable device to measure, for instance, feeding behavior
  • A straight-forward design with reliable technology
  • Easy to clean, simple to connect, no need to calibrate
  • Works regardless of environmental IR light pollution
  • Operated by EthoVision XT Trial &Hardware Control
