Open Field

Open Field / Activity

The open field is a simple apparatus that can be used to measure hyperactivity, exploratory activity, and stereotyped rotation.  Some versions of the task are used to assess anxiety and memory for context.


The subject is placed in the activity chamber for a specified time period.  A video is recorded and analyzed using TopScan for activity levels, behaviors and time spend in various zones of the arena.  The results can be used as evidence of hyperactiviy, hypoactivity, anxiety, explorative behaviors, and stereotyped rotation.

A square arena is typically used for mice while an empty clean water maze tub is used for rats. We have the capability to run up to 4 mice or 1 rat at a time.
