Behavior of a group of rats was observed visually and tape recorded continuously from day 19 till the end of 25-d hypomagnetic experiments. Results were statistically processed with the help of Statistica 6.0, time series spectral analysis, and cosinor analysis. The 25-d HM exposure was shown to suppress food-motivated behavior in the mornings on the background of step-up in serotoninergic processes in the brain, and exaggerate the intraspecific violent conduct at night. The hypogeomagnetic environment impacted diurnal system adaptability to the seasonal light period drifting and produced exo- and endogenous desynchronosis.
