The motor system composes complex actions by combining simpler submovements. This presumably involves sharing information about the progress of one submovement with the centres controlling another submovement, to ensure that the second happens in an appropriate relation to the first. This process is called coordination. In this paper Idiscuss evidence that coordinating actions indeed involves an active process of sharing information about the current state of movements. Coordination appears to be qualitatively different from the process of reacting to external stimuli. This may reflect the importance of predictive representations in coordination. Finally, the processes underlying coordination appear to be organized in a response-specific fashion, as a number of relatively independent circuits. The development and tuning of these circuits may, in part, be what makes an action "skilled". 相似文献

A growing literature has observed a significant reduction in pain sensitivity among hypertensive animals and humans. It is uncertain whether a reduced sensitivity to pain can be observed in nonnotensive individuals who go on to develop high blood pressure. Blood pressure (BP) was reassessed in one hundred fifteen 19-year-old boys initially tested at age 14, when they were also presented with a pain stimulus (mechanical finger pressure). Hierarchical regression analyses indicated that information regarding pain tolerance improved prediction of changes in systolic and diastolic blood pressure beyond that afforded by differences in BP at age 14, parental history of hypertension, and body mass index. These analyses suggest that pain sensitivity may be associated with physiological processes involved in the development of sustained high blood pressure. 相似文献

The study examined physical symptoms and health service utilization of subjects high or low on a measure of the tendency to experience stress somatically and high or low on a measure of current stress. High somatic responders reported greater numbers of symptoms than low somatic responders regardless of stress level. However, high somatic responders who were experiencing high levels of current stress reported significantly more symptoms than high somatic responders who were experiencing low levels of stress. These findings indicate that somatic response to stress reflects both a general tendency to focus on physical symptoms, and a specific tendency to focus more on physical symptoms when under stress. Analysis of health service records indicated that high somatic responders had more visits prompted by symptoms than low somatic responders, but did not differ in frequency of health service visits designed to maintain health. The findings further clarify the relationship between somatic response to stress, physical symptoms and health service use. 相似文献
