A mysterious power of the yellow slime "Mojihokori" that solves the maze and does not have a brain or nerve and shares memory by fusing

ByI-saint

A type of yellow-colored bacteria inhabiting fallen leaves and decayed treesModjocori"Has been found to be equipped with judgmental power and memory power that are comparable to advanced intelligence despite having no" brain "that human beings are equipped with.

Modjocori is a fungus that prefers a humid environment in the shade, and the whole visible one is a cellPolynuclear bodyofSingle cell organismis. The protoplasm that forms the cells movesProtoplasmic flowBy doing so, it has the ability to move from the original place to another place.

There are no advanced organs such as organs and brains of organisms such as human beings in modafokori, a single cell organism. Therefore, it is thought that people do not have the ability to think with using their heads and the ability to judge based on past memories, but in reality they can judge and remember It is known to take actions that can only be thought of as being done.

Ability to connect the two points at the shortest
One is a phenomenon that connects from the entrance of the maze to the exit with the shortest distance. The following movie contains a state taken time lapse of such movement of modifier.

What was prepared is a labyrinthine passage made in a petri dish and a mass of modular dust contained in it.


Mojokori moves the tissue and fuses with adjacent lumps ... ...


The experiment started with the maze filled with Bissiri and Modjocori. This time we are trying to connect the shortest route from "A" to "B".


Next we prepared the mojogori food. It seems that oatmeal is used frequently in the experiment.


Placing oatmeal at A and B ... ...


Mojochori moved and noticed the presence of oatmeal.


The mojikori that found the bait shows a movement that gradually concentrates on the place where the food is located. As mentioned above this is a living being made of one cell and no brain with the power to think.


It seems that modjocori is concentrating in a place where nutrition is efficiently obtained. Therefore, from the part in such blind alley ... ...


The protoplasm had left and the color changed from yellow to transparent.


Ultimately, the maze which had been filled with Bossiri with mojoko is connected by a single line.


And this line was the shortest distance between A and B.


When mojiko spreads, it spreads out the body structure so as to extend branches towards the surroundings. The speed is about 4 cm per hour.

The "ability" of modjocori is demonstrated even if a stage like a maze is not set up. In the following movie, in the stage imitating the Kanto region, the state that Mojihokori draws a line substantially matching the main railway network is contained.

From the center of the stage formed in the Kanto region where it seems to be slightly spread, it spreads out toward the surroundings. The white objects placed in the places are oatmeal placed according to the location of the real major cities.


Mojokori spreading around. I already draw a pattern like a road, but the core is from here.


Sooner or later, a pattern of lines connecting each point was completed. This is similar to that of a real railway network.


The comparison is also described in the following article.

When I put the pattern drawn by Modjokori on the actual map, it looks like "B". Comparing the pattern "C" drawn by Mojihokori with the actual railway network "D", there are minor differences, but the major principle of "linking each point with the shortest distance", both modjocori and human being the same You realize that it is realized. This is one of the reasons that Mojihokori is recognized as something like intelligence.


Incidentally, this experiment was conducted by a research team by Mr. Atsushi Oshii of Hokkaido University's then Graduate School of Science. In this research, in 2008 we received the award for "I discovered that there was the ability to solve puzzles in genuine slime molds of unicellular organisms"Ignor prizeAwarded the Cognitive Science Award.

Based on this paper,SpainIt is said that experiments have also been made to reproduce the transportation network such as the mojiko.

◆ "Memory ability" which is not supposed to be equipped
In addition, events that can only be thought of as "existence of power to memorize", which should not exist in mojokori without brain, have been confirmed. A zoologistAudrey DostourDr. has shown that modjocori has the ability to "learn" by conducting experiments to place disgusting substances such as salt and coffee on the path of moving mojocori.

Mojikori placed an obstacle on the path initially showed a clear response at that place, and the movement was very slow. However, while taking the same action over and over again, Modjocori can memorize the existence of obstacles and learn that there is no problem even if they pass through as it is possible to move without delaying the movement It is said that. Dr. Dustoul says, "Many people say" cells can not learn, "but in our research we confirmed the same thing with more than 2000 members of modjocori, which is not a coincidence event "I am convinced of the existence of memory and learning ability.

Even more interesting is the fact that this "memory" is inherited even when fused with another cell. In the same situation as above, Dousthool observed a completely new mojokori and an experienced modifier of obstacles and how to move. Then, the two modafokori first stuck to each other and fused into one cell body. After that, I started moving in the same way, but at that time I already had learned memory inherited, and I was able to move without obstruction by obstacles. Thus, it has been confirmed that Modifocorum possesses the ability to memorize at the cellular level and has the ability to transmit information to another cell body.

Thus, it is known that even unicellular organisms that do not have a brain are equipped with the ability to judge intelligence and ability to resemble memory. Tanya Rati of the University of Sydney said: "I think that we are beginning to realize that only the brain is a complex and not a necessary condition for intellectual behavior, most of the creatures on Earth have a brain We do not understand how such organisms can adapt to changing environments, but we hope that this research will further study this field, "he says, I talk about the significance of research results.

Such a phenomenon has been confirmed from Mojihokori as to where the source of high intelligence comes from, and furthermore, even though it is made to think of "what is life".
