Just now, I accidentally smashed an antique - woke up in shock - I woke up and heard the sound of glass breaking next door. In this short 0.5 seconds, at the junction between dream and reality, I experienced the most counterintuitive aspect of consciousness: the brain captures the sound, awakens the emotion, and finally I "realize" that someone has broken the glass. Where is it counterintuitive? We've always thought that we "see" and "hear" something before the brain arouses emotion and responds. The fact is just the opposite. The brain first captures the scattered pictures, sounds, and emotions , and after about 25 milliseconds, you "see" the complete picture, and then consciously respond. If it weren't for the dream just now, it would be difficult for us to intuitively experience, the senses and consciousness, which comes first. What can be said about the difference of 25 milliseconds? This gap of lightning and flint has subverted our world view - we know nothing about the real world, and the colorful world in front of us is "fabricated" by our brains. We often jokingly say that brain supplementation is brain supplementation,
but brain supplementation is the phone number list truth. 1. Evolutionary pressure makes our brains love to make up stories Sound weird? Let me be a little more specific: First of all, we need to clarify the most critical point, our consciousness - the inability to touch the "front line" information received by the senses. Take vision as an example. On the surface, the eyes seem to send us real-time high-resolution images, but what the optic nerve really sends to the brain is nothing more than a series of contours and cues of interest points in the visual area. persuasion, storytelling, secondhand world Figure: 7 low-data-rate "images" of the optic nerve filtered to the brain Why did evolution "design" the human brain so strangely that human beings can only live in a fictional world of consciousness and never touch the truth of the physical world? The reason is very simple. Evolution pays special attention to "economics". As the pinnacle of evolution in nature, the human brain, of course, pursues "doing the most with the least energy": due to the amount of information (audio, audio, touch, and touch) that our senses receive at the same time.
Taste, smell, etc.) is too large, and this information floods into the brain nerve center at the same time. If our brain is stubborn to process all the information, it is like driving a Tesla with a power bank, and you have to stop before it starts. So how can the brain obtain accurate external "facts" while processing as little information as possible? Very simple, information filtering and data extraction. It is easy to understand by analogy with business management: the brain consciousness is like the boss of a large group, and the world that consciousness allows you to "see" is like the boss's understanding of the general situation of the group. For example: Jack Ma, how do you manage such a big stall in Ali? Very simple, layered authorization. The physical facts that the group company really interacts with the outside world , for example, how much green energy you bought on Taobao and how much green energy you received in Ant Forest, Jack Ma doesn’t care (though he doesn’t have enough energy), he only cares about the data collected by the subsidiaries. Information (these are not facts, just aggregated data), filter what he thinks is important (consciousness is so subjective), and then present an overview of the group (the vision in Ma Yun's eyes),
