It is known that burst discharges in basal ganglia neurons are more common in parkinsonism than under normal conditions, but changes in the structure of burst or peri-burst epochs have not been reported. In this study, the temporal structure of bursts and the timing of neuronal discharges that precede or follow them were examined in neuronal spike trains(More)
These experiments re-examined the notion that reduced activity in the external pallidal segment (GPe) results in the abnormalities of neuronal discharge in the subthalamic nucleus (STN) and the internal pallidal segment (GPi) and in the development of parkinsonian motor signs. Extracellular recording in two rhesus monkeys, which had been rendered(More)
BACKGROUND Multi-strategic community wide interventions for physical activity are increasingly popular but their ability to achieve population level improvements is unknown. OBJECTIVES To evaluate the effects of community wide, multi-strategic interventions upon population levels of physical activity. SEARCH METHODS We searched the Cochrane Public(More)

There is evidence from observational studies that increasing physical activity may reduce the risk of cognitive decline in older adults. Exercise intervention trials have found conflicting results. A systematic review of physical activity and exercise intervention trials on cognition in older adults was conducted. Six scientific databases and reference(More)
CONTEXT Systematic reviews of public health interventions are useful for identifying effective strategies for informing policy and practice. The goals of this review were to (1) update a previous systematic review of physical activity interventions in Latin America which found that only school-based physical education had sufficient evidence to recommend(More)
This article focuses on results of the systematic review from the Guide for Useful Interventions for Activity in Latin America project related to school-based physical education (PE) programs in Latin America. The aims of the article are to describe five school-based PE programs from Latin America, discuss implications for effective school-based PE(More)
Oscillations with periods in the multisecond range have previously been recorded in basal ganglia neurons of awake paralyzed rats, and in these animals were shown to be increased by systemic dopaminergic stimulation, but not altered by depletion of the nigrostriatal dopamine supply. To determine whether oscillations with frequencies below 0.5 Hz also exist(More)
Spontaneous discharge of basal ganglia neurons is often analyzed with time- or frequency-domain methods. However, it has been shown that sequences of inter-spike interval series are not fully described by such linear procedures. We therefore carried out a characterization of the nonlinear features of spontaneous discharge of neurons in the primate basal(More)
PURPOSE There has not been a recent comprehensive effort to examine existing studies on the resting metabolic rate (RMR) of adults to identify the effect of common population demographic and anthropometric characteristics. Thus, we reviewed the literature on RMR (kcal·kg(-1)·h(-1)) to determine the relationship of age, sex, and obesity status to RMR as(More)
