The ravens are wiser than we expected

 

Scientists have for centuries considered birds to be fools, but the one bird that has always amazed them is the crow.

Over the last few years, science has shown that ravens are capable of making things, storing them and taking care of tools, they can count and practice self-control, they like to play and they have a lot of resentment. Also have

In fact, anyone who has ever encountered a crow knows that this bird is very intelligent when it is also called the adult crow.

But now a new study has shown that it is smarter than we think.

Research has shown that crows are also aware, that is, they are well aware of the world around them, which is very surprising because so far it is believed that only humans and a few mammals have this ability. Is.

The results of the study were published in the journal Science for which German experts worked.

"The results of the study will give us an opportunity to learn about the evolution of consciousness and its brain effects," said Andreas Naider, an animal expert at the University of Tubin.

Animals have difficulty identifying consciousness because they cannot speak, making it difficult for them to know the world around them, to understand what you know, and to think about your knowledge. , It helps in problem solving and decision making, and Koe specializes in both.

In medical parlance, this is called primary consciousness, which is the most basic type of consciousness, ie, the present, near-future and past consciousness, which is related to the cerebral cortex, which is a complex part of the brain of mammals.

But the brain structure of birds is very different, where there are layers in the brains of mammals, the brains of birds are very smooth and so it is in the brains of crows.

But crows are very smart and have the same mental abilities as mammals, and that's why experts were trying to find out if they have consciousness.

To find out, German researchers took two wells and conducted various experiments on them.

First, they were trained in visual motion response, which showed them light on screens and discovered that they could see.

But some of the lights were very difficult to see, and many times they signaled to see the crows, many times they did not.

Each coyote gave 2,000 signals during dozens of sessions while electrodes were placed in their brains to record brain activity.

The researchers said that the experiments showed that the nerve cells in the coyote's brain have a high level of processing, which has an effect on consciousness.

The results of the study confirmed that such consciousness is not limited to humans or a few mammals and does not require a complex layer like the mammal brain.

A separate study from the University of Rohr in Germany, during experiments on pigeons and owls, found that the brain structures of the two birds were strikingly similar to those of mammals.

The team said the results indicated that the ancient microcircuit had undergone evolutionary stages, which had altered the brains of birds and mammals.

Experts in the first study also agreed with this possibility.

It also means that this kind of basic consciousness is more common in birds and mammals than we expect.

If this is proven to be true, then the next question will be whether there is a possibility of secondary consciousness in these creatures.

With such awareness, people have access to their history and plans and are not limited to current awareness.
