Do animals dream? Please, thank you

Scientists have come to the conclusion that most reptiles do not dream; Birds dream, but most species only dream briefly; All kinds of mammals, such as cats, dogs, horses and other domestic animals, as well as elephants, mice, hedgehogs, squirrels, rats, armadillos, bats, etc., will dream, some dream more frequently, some less often; Fish, amphibians, and invertebrates do not dream. When dreaming, people have shallow breathing, rapid heartbeat, increased blood pressure, double cerebral blood volume, and some twitching of the face and limbs.

At this time, the eye movement can be measured with an eye locometer, and fast waves must appear on the EEG at the same time. Therefore, in general, "REM" plus "EEG fast waves" can be used as a marker of dreaming. In some animals using the above method, when the frog is asleep, there are only a few slow wave curves, and there is no "EEG fast wave" and "rapid eye movement" period, so it can be determined that the frog does not dream.

Turtles have "rapid eye movements" and "EEG fast waves" when sleeping, but they are very short, accounting for only 2% of the sleep time. From this, it can be determined that the turtle has very little time to dream. Cats, dogs, and monkeys all have dreams, and the dreams are longer, with monkeys being the longest, dogs being the second, and cats being the shortest.

The study of animal dreaming is a matter of great interest. Animals dream, what exactly do they dream about? There is a great deal of urgency to get to the bottom of this.

However, animals can't speak and can't tell us, which is a real problem. American scientists conducted such experiments on monkeys: a screen was set up in front of a monkey, and the same picture appeared on the screen repeatedly; Whenever this image is shown on the screen, the monkey is forced to push a lever next to him.

If the monkey refuses to perform, hit it with an electric baton. After a few days, the monkey developed a conditioned reflex: as soon as it saw the image, it took the initiative to push the lever.

Later, scientists discovered that the monkey would also push the lever from time to time during sleep. This indicates that the monkey "saw" the image in its sleep. French physiologist Pohill.

Nov did an interesting experiment with cats. He used chemical and surgical methods to block a part of the cat's brain called the pons. As a result of this, when the cat dreams about something, it acts according to the dream.

After the operation, the cat suddenly raised its head in its deep sleep, looked around, and then got up again and walked around in circles, as if looking for food. Suddenly, it raised its front paws, its ears pressed against its head, and lunged at the imaginary enemy. Nove also locked up two cats that had undergone surgery together for observation, and found that the two cats, who had been living in harmony, suddenly started fighting while falling asleep.

To prove that these actions were made in his sleep, Nov deliberately made a noise by striking objects next to the cats and even placed the mice next to them. However, the two cats were indifferent to everything that was happening around them, and they continued to attack their opponents. According to Nove, the two cats are fighting against their dream rivals.

Cats can dream, but they don't dream for more than 5 minutes at a time. Why do animals dream? Zoologists have yet to find an ideal answer.

And, of course, when my puppy sleeps, he can hear it, haha.

Yes. I've done experiments with mice.

Scientists have come to the conclusion that most reptiles do not dream; Birds dream, but most species only dream briefly; All kinds of mammals, such as cats, dogs, horses and other domestic animals, as well as elephants, mice, hedgehogs, squirrels, rats, armadillos, bats, etc., will dream, some dream more frequently, some less often; Fish, amphibians, and invertebrates do not dream.

Dreaming, human cruel with electroencephalogram confirmed.

I think it will, I think about it day and night and dream about it.

Animals dream without anyone knowing.

Zhou Gong is known to every Chinese, I believe that if you accidentally fall asleep while studying in junior high school, you will be said by the teacher "It's a meeting with Zhou Gong", which is actually a dreamSleeping and dreaming are something that everyone has, but animals also dream, and the content of the dream is what happened during the day.

First of all, there are many types of animals, and the dreaming situation is different, and the sleeping time is also differentFor example, the three-toed sloth dreams intermittently, each time it is about 8 minutes, this is because they have to pay attention to the situation around them at all times, and kangaroos, rats and rats usually dodge quite well at night and can not find the animals sleep for about 6 hours, and the cats and dogs we usually raise will also dream, for example, the cat's mouth will move when dreaming, and the dog will kick the legs, which can be seen that animals can also dream.

However, the first problem is solved, animals do dream, the second question is what animals dream about, this problem is not so easy to solve, American biologists have done experiments on monkeys, just asleep monkeys will see a screen repeated ** picture, and then the monkeys go to sleep, and find that they will still push the picture around when they sleep, which means that the repeated ** picture just now has entered their dreams, and their dreams are what they experienced before the dream, Of course, rats have also done experiments, such as letting them walk through mazes during the day, and then testing the hippocampus, which is responsible for the memory part of their brainWhen I went to bed, I was testing my brain waves, and it turned out that they were very similar to those when I walked the maze during the day, and some of them even coincided.

This shows that the dreams of animals are related to the experience of the day, and it is possible to dream about the things they experience during the day, such as the places they see and pass byAlthough it is impossible to determine the picture they dreamed of, after all, they cannot communicate, but at least these two experiments can show that the animals dream about things related to the morning.

Do animals dream when they sleep?

Animals can dream, mammals such as monkeys can dream, reptiles don't dream, animals dream at different times, they dream about what they see during the day.

In fact, every creature has its own thoughts and ideas, like some thoughts of animals are some of their own things, such as finding food or a happy life by themselves, this is their dream, and they will have such dreams when they dream.

Animals also dream, in fact, animal dreams are similar to us humans, they are all strange dreams, or they are dreams in their hearts.

People can dream, so can animals also dream, what can they dream of?

The answer is yes. The sleeping phase of various animals is different, and the story in the dream will be different. The goat is the most difficult animal to fall asleep and sleeps with a groundhog in order to get enough sleep.

When the situation is dangerous, the sound of the groundhog screaming is the "signal" for the goat to escape. When parrots sleep, they often wrap their heads under their wings and constantly make the same snoring sounds as cats.

What is the reason for this? After a long period of observation, the experts concluded that the animals also dreamed. Biologists have confirmed this with a variety of EEGs.

It is true that animals, like humans, produce dreams when they sleep. The difference is that some animals dream a lot and others less. For example, bats, rats, and goats dream more often than humans.

In contrast, reptiles rarely dream, and even occasionally dreams are brief.
