By surgically attaching electrodes to octopuses, researchers have been able to peer inside the cephalopods’ minds for the very first time.
Octopuses possess a brain wave that has never been seen before in animals, along with others similar to those found in humans, first-of-their-kind brain recordings reveal.
The groundbreaking study captured the first ever brain recordings of freely moving octopuses and was performed by implanting electrodes in the animals’ brains and connecting them to data loggers under their skin. The recordings have given scientists the very first inklings into the workings of cephalopod minds. The researchers published their findings March 27 in the journal cell.
"Some of these activity patterns have some similarity to activity patterns observed in the mammalian hippocampus, also a memory center," first-author Tamar Gutnick, a visiting scientist at the University of Naples, told Live Science. "But we also observed unique patterns, 2Hz activity, that were never reported in other animals."
