The geotaxis test is used to investigate motor coordination and vestibular sensitivity in rodents. The rodent is usually placed in an inclined grid in the head downwards position. The grid allows for grip and allows for the rodent to reorient itself towards an upwards position. Both acrylic and stainless steel versions are available through MazeEngineers. The larger angle creates a more difficult barrier towards reorientation. Shallower angles allow for easer geotaxis.
Scoring is done with three categories: measuring the ability to turn upwards within 60 seconds, failure to turn within 60 seconds, attempted but failed to turn within 60 seconds.
