Although you can't have the subjective impression of seeing anything without a visual cortex, you can respond to things captured by your eyes that are processed by these other brain areas.
虽然没有视觉皮层,你不能产生视觉的主观印象,但是你能对眼睛捕获到的信息进行反应,因为它们是大脑的其他区域处理的。
One study showed that we can detect that people are looking at us within our field of view – perhaps in the corner of our eye – even if we haven't consciously noticed. It shows the brain basis for that subtle feeling that tells us we are being watched.
一项研究表明,即使我们没有意识到,我们视线所及的东西还是能被看到。这表明了大脑产生的这种微妙感觉告诉了我们正在被注视。
So when you're walking that dark road and turn and notice someone standing there, or look up on the train to see someone staring at you, it may be your nonconscious visual system monitoring your environment while you're conscious attention was on something else.
所以当你走夜路时回头发现后面有人,或者在火车上注意到有人看你,这些无意识的视觉系统正在监测你周围的环境,而你的注意力显然在其他地方。
It may not be supernatural, but it certainly shows the brain works in mysterious ways.
这并非是超自然现象,但是这表明了你的大脑的确在以一种神奇的方式运转。
