The distribution of gray matter in the two cerebral hemispheres was determined by the xenon-133 inhalation method. There was more gray matter relative to white matter in the left hemisphere than in the right, particularly in the frontal and precentral regions. This finding suggests that the organization of the left hemisphere, relative to that of the right, emphasizes processing or transfer within regions, or both, rather than transfer across regions.
通过吸入氙-133的方法确定了两个大脑半球中灰质的分布情况。相对于右侧，左侧半球中灰质相对于白质的含量更多，尤其是在额叶和中央前回区域。这一发现表明，相对于右侧半球，左侧半球的组织方式更强调区域内的处理或传递，或者两者皆有，而不是区域间的传递。
