In the last few decades, there has been a shift towards a more sedentary behavior during infancy and adolescence. In fact, in most developed countries, the majority of children spend a large part of their leisure time involved in sedentary activities, such as viewing TV, surfing the internet, or playing video games. The modification of these behaviors could have a notable impact on weight control. It is not surprising that some school-based behavioral programs aimed at the reduction of TV viewing, and encouraging a more active use of leisure time, have proven to be among the most effective interventions for the prevention of obesity in children 28-30 .
And upper limb weakness in the hemiparetic arm (i.e., a strength grade of 3 5 or less in muscle groups of the proximal arm) as assessed with the standardized Medical Research Council battery. Patients were randomly assigned to either an experimental or control group. The sensorimotor training for the experimental group consisted of a set of video games in which patients were required to move the robot end-effector according to the game's goals. If the patient could not perform the task, the robot assisted and guided the patient's hand. The sensorimotor training group received an additional 4-5 h per week of robot-aided therapy while the control group received an hour of weekly robot exposure.
An alternative approach to studying the brain suggests that neural efficiency may be related to intelligence such an approach is based on studies of how the brain metabolizes glucose (simple sugar required for brain activity) during mental activities. Richard Haier and colleagues (Haier et al., 1992) cited several other researchers who support their own findings that higher intelligence correlates with reduced levels of glucose metabolism during problem-solving tasks -that is, smarter brains consume less sugar (and hence expend less effort) than do less smart brains doing the same task. Furthermore, Haier and colleagues found that cerebral efficiency increases as a result of learning on a relatively complex task involving visu-ospatial manipulations (the computer game Tetris). As a result of practice, more intelligent participants show not only lower cerebral glucose metabolism overall but also more specifically localized metabolism of glucose. In most areas of their brains, smarter...
Situations such as watching television or reading a book qualify as cognitive inactivity in this setting. In contrast, playing a demanding video game or having an argument can improve RLS. Presumably both factors (immobility and decreased central nervous system activity supporting alertness) contribute to the onset of the condition (13). No specific body position causes the symptoms in RLS. This contrasts with body positional discomfort syndrome, in which a certain supine condition i.e., lying on your right side, is uncomfortable. Pain or discomfort from circulatory compromise or stiffness from prolonged sitting or lying in a fixed position should also not be confused with RLS symptoms.
A remarkable PET study by Koepp et al. (1998) examined in vivo dopaminergic activity during a videogame with monetary reward by measuring 11-C raclopride binding to striatal D2 dopamine receptors. They found that binding was significantly reduced in the dorsal and ventral striatum during the video game compared with baseline levels, consistent with increased dopamine release. Importantly, the binding reduction in ventral striatum positively correlated with the performance level during the task. Thus, the anticipation and outcome of a reward (not separable in this study) activate the dorsal and ventral striatum, and this may be mediated by increased firing in dopaminergic mesolimbic neurons, and increased dopamine release. The more recent fMRI data are consistent with such a conclusion (e.g., Knutson et al., 2001a,b).
