still from the TV series «twilight zone» second season, 2020
The American television anthology was broadcast by CBS from 1959 to 1964. Each episode is a separate story, the characters of which are incorporated in the so-called «the Twilight zone», when faced with unexpected endings and a moral. Last year saw a remake of the cult TV series, and soon arrived, and the second season, one of a series which tells the story of a team of scientists studying a new species of deep-sea octopuses. Populations of squid and octopus, according to the story, has grown to incredible proportions due to climate change. As a result, researchers are faced with the unknown science of intellectually advanced life form. And you know what is most surprising in this story? Octopus really so strange that their tentacles as both are «brain». But that's not all. Tell, what science knows about cephalopod molluscs.
When an octopus wrapped around one of their flexible tentacles a stone or a piece of food, it is not because the animal's brain says: «take this». Rather, a tentacle as if it is «decides» what to do next. It's as if the thumb of your left leg determined where to go. Nervous system of cephalopods is arranged not like a person, and not like other vertebrates. But from which part of the body of the Central brain sends orders to all the others?
In fact, the limbs of the octopus dotted with concentration of neurons, called the ganglia. With the help of the ganglion these «brain-tentacles» can work independently of the Central brain of octopus. Scientists who recently succeeded in visualizing the movement in the tentacles of an octopus, found that the Central brain of an animal with virtually no involved.
The Team presented their findings June 26, 2019 during the scientific conference on astrobiology. The researchers used a camera and software to monitor animal behaviour to simulate how the octopus perceives, and processes information about the environment by means of tentacles, Livescience.
did you know that the squid is very big brain. Scientists believe that they are the most intelligent of mollusks.

Modern technology allows researchers to see how sensory information is integrated into the neural network of the mollusk, when the animal takes difficult decisions. The movement of octopus tentacles starts far from the brain, and is called suction cups (sensors) in the tentacles that explore the seabed or aquarium. Each sucker contains tens of thousands of chemical and mechanical receptors; For comparison, the tip of a human finger contains only a few hundred mechanical receptors.
When an octopus touches something interesting, «the brain» in his tentacles processes the incoming information from the outside and moves the signal further, indicating the hand what to do. The researchers found that the signals generated by one suction Cup, transferred to its nearest neighbor, activating the muscles of the tentacles and wide, generating a wave motion that moves up the body. While the tentacles of the octopus to actively interact with the environment and with each other — the signal that reaches the Central brain of the animal, «highly abstracted» and collaboration «hands» is not directly involved.
twilight zone is not so mad as it might seem at first glance. Great science fiction
In fact, octopus «outsource» calculations about how to control the body, assigning certain actions to the local management bodies of the ganglia that are in each tentacle. In a sense, octopus send your mind to explore the environment, to understand what is happening around about halfway. It's all very entertaining, but for some reason scholars say about the octopus at the astrobiology conference? What has this all relates to extraterrestrial life? That's the reason the representatives of extraterrestrial civilizations are likely to be different from us, read my colleague Ilya Hel.
It is believed that octopuses have a high intelligence, however, ways of perceiving the surrounding world and interaction with them differ sharply from the ways that have evolved in vertebrates reasonable. Thus, the ability of these cephalopods may be an important alternative model for understanding intelligence, and can prepare experts for the recognition of unusual manifestations of intelligent life that originated on other worlds. This gives researchers a glimpse of the diversity of knowledge in the world. And perhaps in the Universe. What do you think, how intelligent octopuses? Response
