| Abstract | |
This study aimed at analyzing the plastic effects of the short-term exercise upon the rat motor area. We check the expression of GluR1 and GluR2/3. We divided into 3 experimental groups based on duration of exercise: 3 days(COR3), 7 days(COR7), and 15 days(COR15); and a control group(CONT). The experimental animals were subjected to a treadmill exercise protocol. The brains were subjected to the techniques of immunohistochemistry and immunoblotting. In the cerebellum, there was a decrease for COR3(17%). In the hippocampus, there was a decrease of the GluR1 expression for COR3 (40%). In the cerebral cortex there was a drop of GluR1 expression for COR3 and COR7(52%). In the striatum, there was no change of GluR1 expression during the first seven days, with a increase for COR15(90%). The GluR2/3 expression did not change in any brain structure analyzed, except in the cerebellum, where there was a significant decrease for two distinct groups, COR3(55%) and COR15(25%). Our data show that short-term physical exercise was able to promote plastic changes during training. (AU) | |
