Effects of exercise in animals with epilepsy have been demonstrated. To investigate whether the type of physical activity, voluntary or forced, would promote different morphological changes in hippocampal formation we performed an immunocytochemical study using the parvalbumin (PV) distribution as a marker. Control rats and rats with epilepsy were submitted(More)
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)
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)
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)
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)
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)
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)
Studies in adult animals have demonstrated a beneficial effect of physical exercise on epileptic insults. Although the effects of physical exercise on the mature nervous system are well documented, its influence on the developing nervous system subjected to injuries in childhood has been little explored. The purpose of our study was to investigate whether a(More)
Neonatal noxious stimulation has been proposed to model pain triggered by diagnostic/therapeutic invasive procedures in premature infants. Previous studies have shown that hippocampal neurogenesis rate and the behavioral repertoire of adult rats may be altered by neonatal noxious stimuli. The purpose of this study was to evaluate whether noxious stimulation(More)
The positive effect of physical exercise programs on seizure frequency and severity has been demonstrated both in adult human and animals. However, this investigation during animal brain development has not been examined. To this purpose, the present work was aimed to analyse the effect of physical exercise training in rats after weaning on the kindling(More)
