The computer must have electricity to start. How does the brain drive it?

The human brain dies without energy. The human brain is more complex than a computer, so it consumes more energy. The food people eat every day is converted into energy, and so is the oxygen they breathe. 25% of this energy is supplied to the brain.

So some programmers just use their brains every day, but they eat as much as athletes.

Because athletes only exercise their limbs, and programmers must use their brains and motors to consume energy.

In a sense, the human brain, like a computer, needs electricity to work.

People's energy will also be converted into electrical energy, and the signals transmitted by nerves are mainly electrical signals.

It should be explained here that all substances in the world, except gravity, are mainly electromagnetic forces.

You know, everything is made up of atoms, and atoms are made up of nuclei and electrons.

Electric energy is generated by the change of magnetic flux in closed-loop wire cutting. The potential difference produces an electric field, which drives the free electrons to move directionally and produces a current.

All living things are made of atoms, so is the human body. Therefore, it is the basic function of biology to maintain the operation and metabolism of the body through electrical signals.

However, bioelectricity is not transmitted like conventional electric energy, but has a special operating mechanism. The human body consists of about 60 trillion cells, and each living cell has a cell membrane potential. Under the action of membrane potential, cells form gradient arrangement of sodium, potassium and chloride ions around them, and carry out metabolic activities through ion exchange.

Through the metabolic activity of cells, we can know that the most important part of the active potential is various mineral ions. Therefore, if the human body lacks certain minerals, the potential in the body will be unbalanced and it will get sick.

For example, potassium deficiency or sodium deficiency will lead to physical imbalance, cause diseases and even endanger life.

The human brain is the most important organ and the most complex organ of the human body.

The reason why human beings have evolved wisdom and become the masters of the earth is mainly the result of the evolution of developed brains.

The human brain is very different from other animal brains in weight, structure and function, especially the complexity of structure and function is incomparable to any other animal.

The brain is the total organ of human consciousness, thinking and memory, and it is the collection, decision-making and command center of perception, feeling and reaction behavior. Once the brain is broken, this person is finished.

The complex structure and function of the brain occupy a lot of space, so I won't go into details here.

Only brain neurons are mentioned here. The whole activity of the brain depends on the transport of nutrients, metabolism and information by brain neurons. It is estimated that there are about 654.38+00 billion neurons in human central nervous system, and there are about 654.38+04 billion neurons in cerebral cortex alone.

These neurons are specialized cell types with discharge function, and they are connected with each other through synapses. Nerve signals are electrically conducted in the form of action potentials in neurons, while they are conducted between synapses by transferring chemical transmitters between neurons.

The brain obtains stimulus information from external perception, processes it, processes it in different categories, or stores it, or remembers it, or gives feedback, and directs the body to respond to various perceptions and stimuli.

It takes energy to keep the brain running efficiently. When people think with their brains, millions of nerve cells are busy and nervously transmitting information. Brain burn? It is not an exaggeration to describe nervous thinking, just right.

Brain burn? It consumes a lot of energy, the weight of the brain only accounts for 2% of the human body weight, but the blood flowing through the brain reaches 2000 ml every day, which is15% of the whole body blood flow; The energy consumed reaches 20% of the total blood sugar of the whole body and 75% of the blood sugar of the liver; Oxygen consumption accounts for 25% of the whole body.

It is estimated that the power consumption of the brain is equivalent to a 25-watt incandescent light bulb.

These energies are obtained and transformed by eating, breathing, drinking water and even sunbathing.
