驾驶是一个涉及多个认知领域的复杂行为。为了确定神经相关的驾驶性能，[O-15]H2O正电子发射断层扫描进行了模拟驾驶任务。与静息状态相比，模拟驾驶增加了小脑、枕叶和顶叶皮质的局部脑血流量（rCBF）。在模拟驾驶过程中，rCBF和驾驶性能的测量之间的相关性进行了评估。有趣的是，丘脑，中脑和小脑的rCBF与完成课程所需的时间呈正相关，扣带回后部的rCBF与任务期间的崩溃次数呈正相关。因此，这些大脑区域可能在维持驾驶性能方面发挥作用。(c)2004年爱思唯尔公司All rights reserved.
Driving is a complex behavior involving multiple cognitive domains. To identify neural correlates of driving performance, [O-15]H2O positron emission tomography was performed using a simulated driving task. Compared with the resting condition, simulated driving increased regional cerebral blood flow (rCBF) in the cerebellum, occipital, and parietal cortices. Correlations between rCBF and measurements of driving performance were evaluated during simulated driving. Interestingly, rCBF in the thalamus, midbrain, and cerebellum were positively correlated with time required to complete the course and rCBF in the posterior cingulate gyrus was positively correlated with number of crashes during the task. These brain regions may thus play roles in the maintenance of driving performance. (c) 2004 Elsevier Inc. All rights reserved.
