Functional MRI evaluation on activation of premotor area in verb-generation task 功能磁共振成像评价动词生成任务中运动前区激活
In two groups, the difficulty of task increased the laterality of prefrontal cortex, premotor area, and inferior parietal lobule decreased, but the laterality of posterior part of inferior frontal gyrus increased. 两组中,与简单计算任务相比,执行复杂计算任务时前额皮层、运动前区和顶下小叶的LI均下降,而额下回后部LI增加。
During simple and complex calculation, the laterality index of prefrontal cortex and premotor area was higher in right handed group than that in left handed group, but the laterality of inferior parietal lobule had no significant difference. 在执行简单计算和复杂计算时,右利手组前额皮层、运动前区LI大于左利手组,额下回后部LI小于左利手组,顶下小叶偏侧化程度两组接近。
Dorsal lateral of left prefrontal cortex, bilateral premotor area, posterior part of inferior frontal gyrus, medial frontal gyrus, and cortex around intraparietal sulcus, posterior part of inferior temporal gyrus, were all activated during simple calculation and complex calculation task. 简单计算和复杂计算均可见左侧前额皮层、双侧运动前区/中央前回、额下回后部、额内回、扣带回前部、颞下回后部、顶下小叶激活。
Animal experiments have found that the non-human primates, premotor cortex, sensorimotor area, frontal, parietal and temple operculum, orbitofrontal cortex and cingulate cortex are associated with swallowing function. 动物实验发现,非人灵长目动物的运动前区皮质、感觉运动区、额叶、顶叶、颞叶岛盖、眶额皮质和扣带回皮质与吞咽功能相关。
