Scientists Record First-Ever Brain Waves from Freely Moving Octopuses

Scientists have successfully recorded brain activity from freely moving octopuses, a feat made possible by implanting electrodes and a data logger directly into the creatures. The study, published online in Current Biology on December 23, 2022 is a critical step forward in figuring out how octopus’ brains control their behavior, and could provide clues to the common principles needed for intelligence and cognition to occur. The open-access article is titled “Recording Electrical Activity from the Brain of Behaving Octopus.”
