There is a great deal of evidence showing the capacity of physical exercise to enhance cognitive function, reduce anxiety and depression, and protect the brain against neurodegenerative disorders. Although the effects of exercise are well documented in the mature brain, the influence of exercise in the developing brain has been poorly explored. Therefore,(More)
Exercise has been found to influence molecular systems important for maintaining neural function and plasticity as well as treatment of neurologic disorders. The stimuli required to elicit plasticity are thought to be activity dependent. Several protocols of physical exercise have been used to explore its effects on brain function. However, it is becoming(More)
We conducted a study to examine whether physical exercise undertaken during the period of postnatal brain development could modify seizure susceptibility later in life. Male Wistar rats aged 21 postnatal days (P21) were divided into two groups: exercise and control. Animals in the exercise group were submitted to daily exercise on the treadmill between P21(More)
The beneficial effects of exercise for people with epilepsy, including reduction of seizure susceptibility, improvement of quality of life, reduction of anxiety and depression, and better social integration, have increasingly been reported. We present data from human and animal studies supporting the role of exercise as a therapy for epilepsy complementary(More)
Aging is often accompanied by cognitive decline, memory impairment and an increased susceptibility to neurodegenerative disorders. Most of these age-related alterations have been associated with deleterious processes such as changes in the expression of inflammatory cytokines. Indeed, higher levels of pro-inflammatory cytokines and lower levels of(More)
In order to investigate whether physical exercise during development would promote changes the calcium-binding protein parvalbumin (PV) expression in the hippocampal formation, we performed an immunostaining study after an aerobic exercise program in rats during adolescent period of life. Wistar rats were submitted to daily exercise program in a treadmill(More)
OBJECTIVE Exercise is known to enhance circulating brain-derived neurotrophic factor (BDNF) levels in healthy humans. BDNF changes have been measured in endurance but not in strength exercise. The present study aimed to investigate whether anaerobic activity such as sprinting differentially alters basal plasma BDNF concentration. METHODS Brazilian(More)
Accumulating evidence indicates that the endocannabinoid system plays an essential role in the development and maturation of the central nervous system. Studies also have demonstrated that neural systems that regulate behavioral responses can be influenced by exercise during development. Exercise and endogenous cannabinoid activity have independently been(More)
Alterations in the function and organization of synapses have been proposed to induce learning and memory. Previous studies have demonstrated that mossy fiber induced by overtraining in a spatial learning task can be related with spatial long-term memory formation. In this work we analyzed whether physical exercise could induce mossy fiber sprouting by(More)
Brain development is a complex process, and stimuli during this developmental period may modulate the brain's functional maturation and determine its lifelong integrity. Human and animal studies have shown that environmental stimuli such as physical activity habits seem to have a favorable influence on brain development. Research on humans has demonstrated(More)
