Octopuses were made friendly by means of ecstasy

Scientists from Johns Hopkins University have found out that the medicine MDMA affects octopuses approximately as well as people. In particular, he does them by more friendly, Eurek Alert reports.

Though a brain of octopuses is more similar to a brain of a snail, than the person, they are known as clever animals. For example, they can entice production by deception. Also scientists assume that they have incidental memory. At the same time the majority of octopuses are quite asocial: they avoid interaction with other animals, including also the fellows. Scientists have decided to check

whether it is possible to change it by means of medicine of the psychoactive medicine MDMA (ecstasy) which influences serotonin neuroregulation mechanisms - happiness hormone. One of effects of MDMA - feeling of a unification with people around and desire of a tactile blizota.

according to scientists in spite of the fact that octopuses and people are divided by 500 million years of evolution, processes of neuroregulation of serotonin at them are almost identical.

"Our researches show that some chemicals in a brain (neurotransmitters) which send signals between the neurons necessary for social behavior evolutionarily remain", - authors write.

They have made an experiment, having placed several males and females of octopuses in containers with MDMA solution which animals absorbed through gills. Then they were put in turn in aquariums with a cage in which there was a live octopus. It has turned out that under the influence of MDMA usually unfriendly octopuses willingly spent time and with other octopus, at the same time they twisted his cage with feelers and tried to reach it. "It is very similar to how people react to MDMA: they too often touch the friend at the friend", - it is said in a research.

Results of experiments still demand confirmation, but they open new opportunities for studying of influence of psychiatric medicamentous therapy on many animals, even very remotely similar to people. 142
