【摘要】 利用功能磁共振成像（ｆＭＲＩ） 技术，研究在处理形状知觉、位置知觉和特定形状图形的空间位置知觉的情况下，人类视皮层背侧（Ｄｏｒｓａｌ ｓｔｒｅａｍ） 和腹侧（Ｖｅｎｔｒａｌ ｓｔｒｅａｍ） 两条通路是怎样反应的。结果发现：形状知觉仅引起腹侧通路的兴奋；空间位置的知觉引起背侧通路的兴奋；特定形状的空间位置知觉引起腹侧通路和背侧通路的共同兴奋。这一结果丰富了对人类视觉皮层的两条通路在功能上定位的认识。更多还原

【Abstract】 The present study, through fMRI, aimed at how the two visual pathways (the dorsal stream and the ventral stream) respond to form perception, spatial localization and a visuospatial task combining form perception and spatial localization. The findings were: form perception only activated ventral stream; spatial localization activated dorsal stream; the visuospatial task combining form perception and spatial localization activated both ventral stream and dorsal stream. These results enriched the knowledge toward the two visual pathways of human visual cortex.更多还原
