也是一只自由泳的小鸟
One researcher told me how his entire career had been devoted to the sensory biology of birds and, apart from once being asked to write a chapter for an encyclopaedia of bird biology, had received relatively little recognition. On retirement he had burned all his papers, and then - to his simultaneous dismay and delight - I started asking him about his research.
Amazingly, we train ourselves to ‘reverse’ the inverse image on our retinas. In a famous experiment conducted in 1961, Dr Irwin Moon wore image-inverting spectacles that effectively turned the world upside down. At first he found it horribly disorientating, but after eight days of wearing the spectacles Dr Moon had adjusted and ‘saw’ the world the right way up again. To prove it, he drove his motorbike and took his plane for a spin – without mishap. Moon’s extreme experiment provided irrefutable evidence that we ‘see’ with our brain rather than with our eyes.
哇，我以前有听说过因为眼睛的成像是上下颠倒的，所以婴儿刚出生的时候看到的世界是反的，后来才调整过来的，原来同样的过程也可以在成人身上实现！大脑好神奇！
我感觉，通感就是大脑处理数据时出了点 bug

@ChuckL 为啥？大家大脑运作的机制不都一样吗
@unagi 我觉得你猜的很有道理
@ChuckL 人的眼睛、耳朵、鼻子等等感官都只是 sensor 而已，最终人体会到什么是由大脑来加工的，所以我觉得可能就是在这个加工的过程中搭错了线，所以产生了通感。
有的人见到一段描写会真的闻到相关的气味，但有的人只是感觉好像闻到了什么东西。前面那种应该就是大脑处理的问题，后者可能就是想象力？
（全都是瞎猜）
