Background: Physical exercise has been long recognized for its therapeutic effects on depressive disorders, but the underlying mechanisms remain largely unknown. In the research, we investigated whether the physical train by voluntary wheel running (VWR) alters depression-like behaviors and its influence on mind Blood Vitals oxygen stage-dependent (Bold) indicators in mice. Ex. The variations in useful brain changes had been decided by Bold purposeful magnetic resonance imaging (fMRI). Results: The results confirmed that VWR train significantly reversed the CUMS-induced behavioral abnormalities. Base on the fMRI amplitude of low-frequency fluctuation (ALFF) analysis, we discovered that VWR exercise may restore the CUMS-induced excessive Bold activation in elements of limbic system, such as cortex, hippocampus and corpus callosum. Furthermore, CUMS-induced Bold suppressive areas were additionally partially attenuated by VWR train, comparable to amygdala, cerebellum anterior lobe, thalamus, midbrain, and pontine. Most of those regions are involved in mood-regulating circuit, suggesting dysfunction of the circuit in CUMS mannequin of depression, and VWR train could modify the temper-regulating circuit. |
