Summary: | In this work we have described the new mathematical approach, with spectral
analysis of the data to evaluate position and motion in the „„open field““
experiments. The aim of this work is to introduce several new parameters
mathematically derived from experimental data by means of spectral analysis,
and to quantitatively estimate the quality of the motion. Two original
software packages (TRACKER and POSTPROC) were used for transforming a video
data to a log file, suitable for further computational analysis, and to
perform analysis from the log file. As an example, results obtained from the
experiments with Wistar rats in the „open field“ test are included. The test
group of animals was treated with diazepam. Our results demonstrate that all
the calculated parameters, such as movement variability, acceleration and
deceleration, were significantly lower in the test group compared to the
control group. We believe that the application of parameters obtained by
spectral analysis could be of great significance in assessing the locomotion
impairment in any kind of motion. [Projekat Ministarstva nauke Republike
