Scientists have discovered unique waves in the octopus brain that are only found in humans

Scientists have discovered unique waves in the octopus brain that are only found in humans. A team of researchers from the University of Naples studied an octopus's brain and concluded that it emits waves that are specific to human brains, but not other living beings. This was reported by LiveScience with a reference to the scientists' publication in the journal Cell.

The octopuses were implanted with special electrodes and then sent to an aquarium. Brain activity was recorded for 12 hours. All this time, the octopuses engaged in typical aquarium activities: exploring space, sleeping, grooming themselves.

As a result, scientists examined the recordings and discovered brain waves in the octopus's brain that can only be seen in the hippocampus of humans. The exact purpose of these waves is unknown, but they are likely responsible for memory formation and sleep. Other animals simply do not have such a tool.

However, many other animals have waves that regulate sleep and wakefulness. They were also found in octopuses.

But the most interesting thing is that scientists recorded previously unseen 2 Hz waves that don't exist in any living creature on Earth, including humans. These are slow, long-lasting pulses that repeat only twice a second.

Octopuses and other cephalopods have long attracted the attention of scientists with their extraordinary intellectual abilities: the ability to perceive their surroundings and themselves, solve complex problems and show at least rudimentary abstract thinking.

The mechanism of camouflage of many octopus species is also amazing, which allows them to change their color quickly. Researchers are sure that this mechanism also helps them communicate and express emotions.
