Chapter 12 Brain Worms
Cerebral worms are not so easy to make. The brain is the most advanced part of the nervous system. It is the organ of thinking. It dominates all activities in the body and adjusts the balance between the body and the surrounding environment. It is also the brain of consciousness, spirit, language, learning, memory and intelligence The material basis of high-level neural activities, such as neurons, is mainly composed of neurons.

Neurons, also known as nerve cells, are the basic units that constitute the structure and function of the nervous system.Neurons are cells with long processes, which consist of a cell body and cell processes.

A sheath surrounds the long axons, which make up the nerve fibers, and the tiny branches at the end of it are called nerve endings.

Each neuron can have one or more dendrites, which receive stimuli and transmit excitations to the cell body.

It can be said that the brain can be made with neurons. Neurons have appeared since the birth of multicellular organisms.

The process of making a brain is more complicated than making a worker bee. Zhang Fan tried to combine neurons in the simplest way.

Endless neurons can be produced by modifying the variation of cells.

But the connected neurons didn't work properly, completely unable to build thought patterns.

Moreover, even the most basic instinctive reaction cannot be realized, and the direction must be wrong.

"Why is there no reason for this?" Zhang Fan drilled into the neurons and observed carefully, and found the most important problem.

That is a short circuit, the neuron generates a small amount of current, and then returns to the original place through the neuron circuit, and the signal is not accurately transmitted.

Zhang Fan is neither a doctor nor a scientist. He has never studied artificial brains, so he really knows nothing about such things.

What he has is endless opportunities, opportunities to try again and again.

Although the geese pass without a trace and the years are silent, the time that passes by is flowing without a trace in every gap in life.

Zhang Fan felt that he was going crazy. The brain he managed to create survived for an hour before dying.

Brain death is very normal, and the movement of the brain must consume a lot of energy.

The success of this experiment also laid a solid foundation for Zhang Fan, and soon the second brain took shape.

He was observing the operation of the information in his head, and not long after, this head also died.

It should be regarded as a success, at least Zhang Fan knows that the brain will not be short-circuited now.

Next is the design of external organs and supply organs.

Breathing is a unified mechanism, skin breathing.

By the way, here Zhang Fan noticed that the oxygen content in the air became richer.

It was a long time ago, and Zhang Fan estimated that it must be because other biospheres began to flourish and the vegetation increased.

The higher the oxygen content in the air, the greater the chance of life ashore.

The brain of a brain worm can occupy 80.00% of the weight of the body, so the skin on the head area should be designed to be large, and it should be covered with an exoskeleton for protection, a thin layer is enough.

The digestive organs must also be large, otherwise the brain will die if the energy is not supplied.

Cerebral worms must also have a certain ability to move. Cerebral worms lacking muscle cells can only crawl through tiny joints.

So Zhang Fan planted tens of thousands of legs at the bottom of the brain worm. If you didn't look carefully, you would think that the brain worm crawled by muscles.

The Cerebral Worm is the largest creature in the entire Zhang Fan biome, reaching one meter in size and 1.5 meters in length.

Zhang Fan's thinking consciousness entered the inside of the cerebrum, and the place was empty and white.

But there is a green planting that is sprouting and thriving.

Zhang Fan tried to communicate with it but got no response, the embryo needs a period of time to grow.

In the completed honeycomb, a germ chamber was opened for the brain worm, surrounded by a lot of nutrients and rich in oxygen.

The cerebrates under such extravagant conditions soon woke up.

Now the brain worm also needs eyes, which are photosensitive organs composed of two cells.

One photoreceptor cell receives light stimulation and converts it into an electrochemical signal, and the other pigment cell blocks the light from the other side, allowing organisms to perceive the direction of light source.

The finished eyes were installed on the brain worm's head, and then the brain worm slowly opened its eyes.

He looked at the surrounding environment curiously, and the tentacles in his mouth kept devouring the surrounding nutrients.

The brain worm's eyes are small compared to the whole body, but this does not affect its observation.

Zhang Fan began to establish contact with the cerebrum, and the first command "respect" was issued, and then Zhang Fan influenced the cerebrum's thinking through his own thinking, and the cerebrum accepted the concept of respect in an instant.

The brain worm's big round eyes began to narrow slightly, and then looked towards the ground, with its whole head lowered as if bowing.

Then Zhang Fan gave the order to let the cerebrum go out. He didn't intervene, but guided, just like parents teaching their children to let the cerebrum learn step by step.

After several days of teaching, the cerebrates have initially mastered the survival instinct and understood their position in this biological group.

Quietly basking in the sun on the moss, when hungry, worker bees will naturally bring food over, and when tired, they hide in the hive to rest, and live freely.

It is the supreme ruler except Zhang Fan.

A brand new embryo was created inside the hive. Once the brain worm died, all the information would enter this embryo, and the modified cells would start to produce new brain worms by themselves.

As a result, Zhang Fan fell silent again, leaving everything to the cerebrum to take care of, while his thoughts drifted away with the spores.

The western part of the mainland is a desert. In winter, it is difficult for the sea breeze to blow to the land, and in spring and summer, the southeast wind blows, so this place is desolate.

But life once again explained to us what tenacity is.

A plant called coniferous grass was born here. The rhizome structure is extremely developed, and the short needles on the ground absorb sunlight for photosynthesis.

In addition to conifers there are many drought-tolerant plants, which are not easy to find, hiding in the thick sand.

In this desert area, there is a kind of miraculous creature. Its whole body is covered by an exoskeleton, and there is no muscle structure inside. The exoskeleton is connected by nerves. It feeds on the juice of plants and can survive for several months at a time.

This kind of creature has broken away from the category of arthropods, and it is better to call it a neurological exoskeleton creature.

I don't know how nature bred such a magical creature.

There are not many of them, they belong to sexual reproduction, and their spawning grounds are generally in the rhizomes of plants.

Whenever this kind of creature starts to break its shell, it will cause the death of drought-tolerant plants. Zhang Fan calls them springtails.
