Abstract

We compared three-dimensional structure-from-motion (3D-SFM) processing in awake monkeys and humans using functional magnetic resonance imaging. Occipital and midlevel extrastriate visual areas showed similar activation by 3D-SFM stimuli in both species. In contrast, intraparietal areas showed significant 3D-SFM activation in humans but not in monkeys. This suggests that human intraparietal cortex contains visuospatial processing areas that are not present in monkeys.

摘要

我们使用功能磁共振成像比较了清醒猴子和人类的三维运动结构（3D-SFM）处理过程。枕叶和中级纹外视觉区域在两个物种中对3D-SFM刺激均表现出相似的激活。相比之下，顶内区域在人类中显示出显著的3D-SFM激活，而在猴子中则没有。这表明人类顶内皮层包含猴子所没有的视觉空间处理区域。
