Abstract Background Regular moderate physical exercise is an established non-pharmacological form of treatment for depressive disorders. Brain lateralization has a significant role in the progress of depression. External stimuli such as various stressors or exercise influence the higher functions of the brain cognition and affect . These effects often do not follow a linear course. Therefore nonlinear dynamics seem best suited for modeling many of the phenomena and putative global pathways in the brain attributable to such external influences. Hypothesis The general hypothesis presented here considers only the nonlinear aspects of the effects produced by moderate exercise and chronic stressors but does not preclude the possibility of linear responses. In reality both linear and nonlinear mechanisms may be .
