How does the human brain work? What is the storage capacity of a computer hard drive?

The human brain is indeed very magical, it can remember so many things, when I was a child, I was still growing up, many of them are memories with pictures, and even when I am old, I will remember the things when I was a child, that is, people use their brains to remember all their lives.

So how much can the human brain store?

According to an article in Nature in March 2014, scientists analyzed the brain of a mouse, which has 13 neuronal structures, and only 13 neurons were analyzed, using up to 1TB of data. The human brain has about 100 billion neurons, so it is 100 million terabytes and 100 million 2t hard drives.

The human brain is a supercomputer.

Human beings have about tens of billions of brain cells, each brain cell has about hundreds of cranial nerves, each nerve has about hundreds of synapses, each synapse has hundreds to thousands of proteins, a brain cell is about the same as a large computer, and a synapse is about the same as a chip of a computer. It can be easily deduced that the human brain is equivalent to hundreds of billions or trillions of chips.

The largest parallel computer in the United States, the White ASCI in the United States, has only 8,000 chips, which is about 100 million times different from the human brain, that is, 8 to 9 orders of magnitude.

The computing power of computers is generally counted by how many addition operations can be done in one second, and the fastest is China's "Tianhe-2", which ranks first with excellent performance of billions of operations per second at peak computing speed and billions of double-precision floating point operations per second at sustained computing speed.

Because the human brain is a super huge parallel computing system, all synapses and all proteins on each synapse can move at the same time in an instant, and the proteins are only a few nanometers apart, and the current can run hundreds of billions of times in a second at this distance, and the human brain's computing speed is indescribably large, about 1 followed by 27 zeros to 30 zeros. You know, 4 billion times, it's just 4 followed by 9 zeros, a difference of about 20 orders of magnitude.

So, if computers were to simulate the function of the human brain, it would take about 100 years to achieve it at the current rate of research. Because according to the famous "Moore's Law", the computing speed of computers doubles every 18 months, that is, about twice every year, and it will take more than 100 years to increase by 20 orders of magnitude.

Now we have created a lot of high-tech and used computers to do a lot of impossible things, so the human brain can even surpass computers, because computers are created by humans, but computers have capacity limitations. At this time, some people asked, how big is the capacity of the human brain? Once the human brain is fully developed, it cannot withstand such tremendous stress.

Those who often say that they have a bad memory and can't remember all the seven words and four lines of the school really can't remember, but they can't concentrate and concentrate leads to inner tension, and naturally they can't remember the problem. More cells in the brain are unemployed, and humans are not making full use of all of them. The practical application of the average human memory is only a quarter of that of the brain, which is the main basis for many people to believe that human potential is still enormous.

It weighs about 1400 grams, the thickness of the cerebral cortex is about 2-3 mm, and the total area is about 2200 square centimeters.

A person's brain has the capacity to store information equivalent to 10,000 libraries, 10 million books. Saying that small is infinitely small, can it hold a little bit of fragmentation when you open the lid of the human brain? This morning, when I was clear-headed, I walked into a small supermarket.

I bought a little old and bad stuff. Finally, how much did each item go? I would have no idea the unit price of each piece, and my mind would go blank.

Rather, it's a worthless analog computer. The hard disk universe is the human brain, and the human mind is never-ending. Sometimes I think of mountains and rivers, sometimes I think of cosmic nebulae, sometimes I recall the past, sometimes I look forward to the future, sometimes far and sometimes near, people are the most expensive, and all things are born from people.

The brain mind is never-ending, and the universe is never-ending. Memory is the interaction between nerve cells in the brain, some short, some long, and some in between, forming our long-term memories, short-term memories, and forgetting some memories. There is a gifted child who can draw everything he sees.

So he sat on the plane and looked at the whole city, and he painted everything he saw. It's equivalent to obliving. Therefore, the capacity of the human brain and memory capacity should have unlimited potential, how to tap it.

The storage space of the brain is equivalent to 7.7 billion terabytes, which is still very large, because no computer device in the world can have such a large storage capacity.

At 7.7 billion TB, the storage space of the human brain is still very large, but the area developed by most people's brains is not very large.

According to scientific research, the human brain has about 100 billion neurons, which is equivalent to 7 billion terabytes of storage.
