Abstract EN
During the neonatal period, the brain is susceptible to external influences.
Exposure to stressful events during this phase of life influences brain development and impacts adult life.
In animals, the maternal deprivation (MD) model is effective in mimicking stress in the early stages of development.
In contrast, physical exercise seems to be able to prevent deficits in memory consolidation.
Although the effects of chronic exercise in cognition are already well established, little is known about the effects of acute aerobic exercise.
Here, male Wistar rats divided into deprived (MD) and nondeprived (NMD) rats were submitted to the object recognition (OR) memory test.
Immediately after OR training, some of the rats were submitted to a single aerobic exercise session for 30 minutes.
Memory consolidation and persistence were evaluated by retention tests performed 24 h and 7, 14, and 21 days after OR training.
We show that a single physical exercise session is able to modulate learning by promoting memory consolidation and persistence in rats with cognitive deficits induced by MD.
Hippocampal dopamine levels, measured by HPLC, were not altered after OR training in rats that performed and in rats that did not perform an exercise session; on the other hand, while OR training promoted increase of hippocampal norepinephrine in NMD rats, the MD rats did not present this increase, regardless of the practice or not of exercise.
