Octopuses can see nightmares: scientific discovery

Octopuses have always been a mystery to scientists. Their unusual appearance, intelligence and ability to change skin color are of interest not only to biologists, but also to the general public. Recently, researchers from the Center for Brain and Cognitive Sciences at the University of Saskatchewan (Canada) discovered another amazing ability of octopuses – they can dream.

How does this happen?

During sleep, octopuses are active in the same areas of the brain as humans. This was revealed using an electroencephalogram (EEG). Scientists have noticed that during sleep, octopuses experience various emotions and movements that are similar to human dreams. They may even react to what happens during sleep, such as changing the color of their skin.

What does it mean?

The discovery made by Canadian scientists can help us better understand how the brain works not only in octopuses, but also in other animals. In addition, it may lead to new methods for studying the human brain and treating certain diseases. For example, neuroscientists can use this information to develop new treatments for insomnia.

Octopuses are real intellectual giants of the marine world. They have a huge number of neurons, surpassing the human brain. Therefore, it is not surprising that they are able to experience emotions and dream.

Interestingly, octopuses have their own sleep preferences. For example, they prefer to sleep on the bottom of the sea rather than on the surface. This is due to the fact that at the bottom of the sea they feel more protected and can sleep more peacefully.

In addition, octopuses can change their skin color while they sleep. This may be due to the fact that they experience emotions and have dreams that evoke certain color associations in them.

Historical context

Interest in octopuses has existed for a long time. In ancient times, they were considered mythical creatures with unusual abilities. For example, the Greeks believed that octopuses could predict the future. Their images are often found on antique vases and frescoes.

However, only in recent years have scientists begun to seriously study octopuses and their abilities. Thanks to new technologies and research methods, we can learn more and more about the life of these amazing creatures.

Expert opinion

Professor Michael Levitt, renowned neuroscientist and Nobel laureate in Physiology or Medicine, commented on the new discovery:

“The discovery that octopuses can dream is a very important step in understanding how the brain works not only in animals, but also in humans. This opens up new possibilities for brain research and the development of new treatments for certain diseases. In addition, this confirms that we are all connected to each other in this world, and that we can learn a lot about ourselves by studying other living beings.”
