Open Field Cages

The Open Field is used to assess exploratory behavior and validated for use in the measurement of anxiety related behaviors.The Ugo Basile Open Field Cage is available in two different sizes and in a number of different versions, to match different experimental needs. Open Field Cages can also be conveniently used for novel object recognition  (NOR) test.

Walls can be quickly detached from the bottom, for ease of cleaning and storage.

All Animal Mazes manufactured by Ugo Basile are designed to give optimal results with any Video-Tracking software. This is achieved by:

  • high-contrast colors: grey, white, black or the NEW Ugo Basile light-blue
  • non-reflective surface: reflections are a common source of error in animal tracking. Let’s avoid them!

All materials were selected to be sturdy and easy to clean, to construct reliable and durable devices. Surface texture was selected for best rodent comfort (reasonably rough, “warm” surface).

The Mouse model is dimensioned 44x44cm, according to the requirements of Eumorphia Empress SOPs; walls are 30cm tall, available in transparent Perspex or grey PVC. A special model of mouse cage is available, dimensioned 40x40cm, with uprights to fit infrared sensor, for combined recording of horizontal (videotracking) and vertical (sensors) activity.

The Rat cage is 100x100cm (inside dimensions 92x92cm), with 40cm tall walls. The larger cage is also available with optional dividers to create four 46x46cm arenas, see model 47150.

    Developed by Calvin S. Hall in 1932, the open field test (OFT) is an experiment used to assay general locomotor activity levels and anxiety in rodents in scientific research and willingness to explore in rodents (exploratory behavior).

    Rrats and mice display a natural aversion to brightly lit areas: they also have a drive to explore a perceived threatening stimulus. The result of these two conflicting drives is anxiety. Decreased anxiety leads to increased exploratory behaviour. Increased anxiety will result in less locomotor motion and preference for the edges of the field.

    The open field is an arena with walls to prevent escape. In the modern open field video cameras with associated software are used to automate the assessment process.
    The relation between the OFT and other tests of exploratory activity as elevated plus maze have been analyzed in two mouse strains. Changes in these measures are often used to assess the sedative or stimulant effects of pharmacological agents.
