Abstract
Behavioral assay for general locomotion in mice.
Materials
  • Open field arenas: 40 x 40 dark box
  • Recording camera
  • Ethovision XT v11
Habituate naive mice to the room for Duration01:00:00 .
1h
Transfer each mouse to a custom 40 cm x 40 cm dark box, with a clear floor and a light suspended on the center of the apparatus.
Test duration was set at Duration00:20:00 .

20m
After each test and between each group, clean apparatus thoroughly with 50% ethanol followed by water.
Analysis:
  • Center of open field is defined by the space located at least 5 cm from any given wall.
  • Time in the center, distance travelled, and average speed is obtained by the built-in functions of the tracking software Ethovision XT11.
