This Is An Octopus’s Brain on Ecstasy

Prone to party fouls like avoiding social interaction and attacking each other, octopuses, when placed in a chamber and given MDMA that seeps into their gills, “tended to hug the cage and put their mouth parts on the cage … they touch each other frequently.” As it turns out, the brain of an octopus on ecstasy bears striking resemblance to that of humans, thanks to similar manifestations of the mood regulator serotonin. This could prove useful in brain research down the line. But for now, we at least know that while we may be separated by 500 million years of evolution, these “gelatinous invertebrates” can, with just a little neuronal nudging, become party animals.
