I see animals in a dream

If animals, like us, have dreams, where our furry friends are carried away in their dreams? Jason Goldman is looking for ways to peek into the minds of sleeping cats, birds and other living creatures.

“It was noted that almost all other animals, whether aquatic, aerial or terrestrial, undoubtedly fall into a dream state,” wrote Aristotle in his treatise “On sleep and wakefulness”. But see “other animals” dreams?

This Greek philosopher also had an opinion. In the “History of animals”, he wrote: “Dreams see not only people but also horses, dogs, bulls, sheep, goats and the whole genus of viviparous quadrupeds. This is proved by the fact that dogs bark while you sleep”. Perhaps his methods lacked depth, but it is likely that Aristotle is not too far from the truth.

Of course, we can’t ask animals if they can see dreams, but we at least can say: we have evidence that this is likely. There are two methods used by scientists to solve this seemingly impossible task. The first method is to observe the physical behavior of animals during the different phases of the cycle “sleep-Wake”. The second is whether their brain in the sleep state similarly to how this state operates our brain. Continue reading

What dreams they see animals

“It is noticed that almost all animals, whether aquatic, aerial or terrestrial, it is evident fall into a dream state,” wrote Aristotle in his treatise “On sleep and wakefulness”. But go to our “lesser brothers” in their dreams?

Jason Goldman, a graduate student at the University of southern California (Los Angeles), evolutionary psychology examines human and animal. The young scientist said that today there are two main ways to look into the minds of sleeping cats, birds and other living creatures. The first method is to observe the physical behavior of animals during the different phases of the cycle “sleep-Wake”. The second is whether their brain in the sleep state similarly to how this state operates our brain.

Since school biology lessons, we know that during sleep the brain passes through several periods with different activity levels. One of them, with relatively lower activity, called slow wave sleep. The second, during which brain activity is almost the same as during wakefulness, was named the fast phase, or REM-phase (from the English. REM – rapid eye movement, rapid eye movement). At this time, the spinal cord sends a powerful braking impulses, paralyzing all our body and making it impossible to move, speak or scream. Continue reading

Bengal cat

Cats of this breed resemble their “ancestors” leopards, because the breed was developed thanks to the purposeful crossing of wild Asian leopard cat and an ordinary domestic cat. And the Asian leopard cat belongs to the subfamily of Panthers (as well as more “serious” animals – leopard, tiger, lion). As we see, attempts of this crossing has yielded its fruits, although at first the males of the first generations were not able to reproduce offspring, and the kittens of this breed appeared due to females-cats and their “linkages” with domestic cats. Thus was derived to reproduce offspring. The Bengal cat is a rare breed in our country. Yes in other countries it is not very numerous. And, meeting these cats for the first time, paying attention to their unusual appearance, “newcomers” even I prick up my ears, I’m afraid. But people who are familiar with the cats of this breed love them very much, just not the soul of tea. In principle, such a versatile attitude to these cats is not surprising, since she was bred with the intention that by their very existence show the tenderness and affection of a forest predator to a pet, the animal in hand. The idea was to get people to think about the dangers of the destruction of leopards – in fact, seeing a Bengal cat, people will correlate this image with the house and calm, not predation. This idea belonged to the American biologist, author of the experiment – Jane mill. By the way, between the British and prodiamesinae there are differences, but they are not particularly significant.
