我们使用PET技术来确定视觉信号是否到达专门用于视觉运动的视觉区V5，当一个被V1区病变致盲的人类患者辨别视觉刺激的运动方向时，通过他的口头报告，他有意识地意识到视觉刺激的性质及其运动方向。结果表明，V5区是活跃的，而没有V1区的平行激活，这意味着视觉输入可以到达V5，而不首先通过V1，这样的输入是足够的识别和有意识的视觉刺激意识。
We used the technique of PET to determine whether visual signals reach visual area V5, specialized for visual motion, when a human patient, blinded by a lesion in area V1, discriminates the direction of motion of visual stimuli and shows, through his verbal reports, that he is consciously aware of both the nature of the visual stimulus and its direction of motion. The results showed that area V5 was active without a parallel activation of area V1, implying that the visual input can reach V5 without passing first through V1 and that such an input is sufficient for both the discrimination and the conscious awareness of the visual stimulus.
