Open field (animal test)

In the modern open field apparatus, infrared beams or video cameras with associated software can be used to automate the assessment process.

Recent research has demonstrated that anomalous diffusion in fractional Brownian motion (fBm) models can effectively characterize typical animal movement patterns through two distinct asymptotic scaling regimes, which are separated by a specific crossover point.

Furthermore, the movement model identified in this study is linked to conventional parameters, such as level crossing statistics that describe zone transition events.

[11] The paper[12] presents an early validation of an innovative animal tracking tool and a model-based approach to gait analysis.

The methodology primarily leverages random walk class models, including fractional Brownian motion (fBm) and its modifications.

Newer drugs such as 5-HT-1A partial agonists and selective serotonin reuptake inhibitors, which have also been proven to treat anxiety, show inconsistent results in this test.
