The rate of local cerebral glucose metabolism was measured in subjects receiving a verbal (n = 4) and a spatial (n = 4) task. The verbal task produced greater metabolism in Wernicke's area relative to the right hemispheric homotopic region, whereas the spatial task produced greater metabolic activity in the right hemispheric homotopic region. Broca's area and its right hemisphere counterpart showed symmetrical activity during the verbal task, but there was a significant asymmetry to the right during the spatial task. Lateralized task effects were also obtained in the frontal eye fields, supporting a hypothesized neural network linking cognitive activity with motor orientation.
在接受语言任务(n = 4)和空间任务(n = 4)的受试者中测量了局部脑葡萄糖代谢率。与右侧半球同位区域相比,语言任务在韦尼克区产生了更高的代谢;而空间任务在右侧半球同位区域产生了更高的代谢活性。在语言任务期间,布洛卡区及其右侧半球对应区域表现出对称活动,但在空间任务期间右侧存在明显不对称。在额叶眼区也获得了偏侧化任务效应,支持了将认知活动与运动定向联系起来的假设神经网络。
