| Research Abstract |
To understand mechanisms of modified physical activities, we studied neuropsychological characteristics in SPORTS rat. In the hippocampus of SPORTS rats, the levels of norepinephrine (NE) in the extracellular fluid were increased, whereas those in the whole homogenate of the tissue were decreased. The protein expression and the activity levels of monoamine oxidase A (MAOA) were decreased in the hippocampus of SPORTS rats, suggesting that the elevation of extracellular NE by decreased MAOA activities in hippocampus determine the neural basis of the psychological regulation of exercise motives in the SPORTS rats.
