The open field is an arena with walls to prevent escape. Commonly, the field is marked with a grid and square crossings. The center of the field is marked with a different color to differentiate from the other squares. In the modern open field apparatus, infrared beams or video cameras with associated software can be used to automate the ...
The hole-board test (HBT) is an experimental method used in scientific research to measure anxiety, stress, neophilia and emotionality in animals. [ 1 ] [ 2 ] [ 3 ] Because of its ability to measure multiple behaviors it is a popular test in behavioral pharmacology , but the results are controversial.
The test rather reflects the anxiolytic effects of antidepressants and the response is seen only after chronic treatment with antidepressants. Elevated plus maze. Open field: [38] Rodents tend to avoid brightly illuminated areas, and this avoidance is interpreted as a symptom of anxiety. Open field is a bright enclosure and during the test ...
The tail suspension test (TST) is an experimental method used in scientific research to measure stress in rodents. It is based on the observation that if a mouse is subjected to short term inescapable stress then the mouse will become immobile .
Schematic drawing of an elevated plus maze. The elevated plus maze (EPM) is a test measuring anxiety in laboratory animals that usually uses rodents as a screening test for putative anxiolytic or anxiogenic compounds and as a general research tool in neurobiological anxiety research such as PTSD and TBI.

Rodents have been employed in biomedical experimentation from the 1650s. [1] Rodent studies up to the early 19th century were mainly physiological or toxicological.The first rodent behavioral study was carried out in 1822, a purely observational study [2], while quantitative rodent behavioral testing began in the late 19th century [1] [2].

The test was first developed by Dr. Carol Barnes in 1979. [1] The test subjects are usually rodents such as mice or lab rats , which either serve as a control or may have some genetic variable or deficiency present in them which will cause them to react to the maze differently.
