From Nell Greenfieldboyce:


The drug makes the usually antisocial creatures much more interested in friendly contact with other octopuses. It's one more sign that the chemistry of social behavior has deep evolutionary roots.

When people take MDMA, the drug popularly known as ecstasy, a rush of serotonin, dopamine, and oxytocin produces feelings of emotional closeness and euphoria, making people more interested than normal in connecting with other people. Now, researchers reporting in Current Biology on Sept. 20 have made the surprising discovery that a species of octopus considered to be primarily solitary and asocial responds to MDMA similarly: by becoming much more interested in engaging with one other.

By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or 'ecstasy,' scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree.

From Jason Weisberger:




Scientists found that the genetically-distant-from-humans octopus also gets more friendly on MDMA.

Honestly, this study doesn't sound so "unbelievable" to me but drugs are fun. I don't like MDMA because it made me want to hug people I know are jerks.

Via Gizmodo:



The fun began when the researchers gave MDMA to seven Octopus bimaculoides octopuses inside laboratory tanks. They hoped to test whether the animals behaved more socially after receiving a dose of MDMA—a sign that the drug bound to their serotonin transporters.

After hanging out in a bath containing ecstasy, the animals moved to a chamber with three rooms to pick from: a central room, one containing a male octopus and another containing a toy. This is a setup frequently used in mice studies. Before MDMA, the octopuses avoided the male octopus. But after the MDMA bath, they spent more time with the other octopus, according to the study published in Current Biology. They also touched the other octopus in what seemed to be an exploratory, rather than aggressive, manner.

The scientists took this to mean that despite our vastly different brains, social behavior is built into the very molecules coded by our DNA, Dölen explained.

“An octopus doesn’t have a cortex, and doesn’t have a reward circuit,” Gül Dölen, assistant professor of neuroscience at Johns Hopkins University, told Gizmodo. “And yet it’s able to respond to MDMA and produce the same effects, in an animal with a totally different brain organization. To me, that means we really need to appreciate that the business end of these things is at the level of the molecule.”

The mood-altering drug MDMA -- which promotes positive, friendly social interactions in humans by inhibiting serotonin uptake in nerve cells -- has a similar behavioral effect in an octopus species, scientists reported today. This indicates that serotonin has been functioning as a regulator of social behavior for at least 500 million years, when the human and octopus lineages evolutionarily diverged.

From Hannah Devlin Science correspondent:

Normally antisocial sea creature becomes friendly and tactile after being given the drug, scientists say

What happens when you give an octopus MDMA? It sounds like a question that might flit through the meandering mind of someone who had been dabbling in psychedelics. But now the matter has become the focus of an unlikely-sounding scientific experiment to uncover the ancient origins of social behaviour.

By showing that the normally antisocial sea creature became friendly and tactile after being given MDMA, also known as ecstasy, scientists believe they have made a link between the social behaviours of humans and a species from which we are separated by more than 500m years of evolution.
