Home Cage Activity: Opto-M4 with MDI Software

The Columbus Instruments Opto-M4 is our general purpose activity meter for measuring locomotor activty. The system is available in a variety of configurations with different possible sensor lengths to accomodate a variety of cages. The Opto-M4 is our solution to monitoring ambulatory, stereotypic, and rearing activity in many cages as economically as possible.

The activity sensors are manufactured in a variety of lengths to accommodate almost any cage size. Additionally, the smallest sensors are made with IR beams spaced closer together at 0.5" (1.27 cm) for higher resolution in mouse cages. We offer the following options:

System can be configured with activity sensing along a single axis of movement for economy, or with vertical sensors and/or a 2nd horizontal sensor for dual and triple axis activity monitoring. Additionally, sensors can be rearranged (additional brackets required) to monitor more cages with fewer axes, or fewer cages with more sensors. Contact our sales department with your application notes for exact system specifications to fit your needs.

This product is the modern implementation that replaces these Legacy Products:

A feature unique to Opto-M4 system is the ability to re-arrange the sensor sets to cover more more cages with fewer axes of measurement, or fewer cages with measurement in more axes per cage.

Flexibility Example 1:

A system purchased for Open Field measurement in 2 cages in X, Y and Z (rearing) axes...
2X-XYZ Axis Configuration

can then be reconfigured to measure general locomotor activity and rearing in 3 home cages...
3X-XZ Axis Configuration

or measure general locomotor activity only in 6 home cages.
6X X Axis only Configuration

Flexibility Example 2:

The distance between sensors is adjustable for X and XZ axis setups. Adjustable Width

Data Collected

  • The interval number (Int)
  • The cage number (C#)
  • The interval start time (Start)
  • The interval stop time (Stop)
  • The stereotypic time (small movements) in seconds (ST sec)
  • Ambulatory counts - number reported for each axis (Xamb and Yamb)
  • Vertical sensor counts - total counts from the Z axis sensor (V1C)
  • Second vertical sensor (V axis) counts (V2C)
  • Second vertical sensor (V axis) breaks (V2B)

Data Calculated

The following parameters can be calculated post data acquisition in Excel or similar program:
  • Distance Traveled
  • Stereotypic Time
  • Ambulatory Time
