This is consistent with previous research, which has found that not only do octopus arms forage independently of the brain, but that they can continue to respond to stimuli even after being severed from a dead animal.
"The octopus' arms have a neural ring that bypasses the brain, and so the arms can send information to each other without the brain being aware of it," said behavioural neuroscientist Dominic Sivitilli of the University of Washington. He said, "This is a complex animal. "That's gotta be difficult that they live such short lives," said Reid. And now scientists have determined that those neurons can make decisions without input from the brain.
"The octopus' arms have a neural ring that bypasses the brain, and so the arms can send information to each other without the brain being aware of it," said behavioural neuroscientist Dominic Sivitilli of the University of Washington. Octopus, squid and cuttlefish -- collectively known as cephalopods -- have strange, massive, distributed brains. Octopuses have large numbers of neurons located near their eyes and others inside their arms. It's making decisions all the time. The Octopoda consists of around 300 known species and were historically divided into two suborders, the Incirrina and the Cirrina.
The nervous system of cephalopods is the most complex of all invertebrates.
"I believe if I've got a soul, this octopus has a soul," she replied. It's so wack that octopuses are often considered as close to alien as a terrestrial intelligence can be (and in one memorable proposal, maybe even actually alien).
That's right, an octopus has one large central brain, and eight mini-brains, one in each arm. An octopus's brain-to-body ratio is the largest of any invertebrate. The team gave the cephalopods a variety of objects such as cinder blocks, textured rocks, Lego bricks and puzzle mazes with treats inside, and also filmed them while they were foraging for food.

Little wonder, considering they are a bit unusual.
Young's attempts to understand mechanisms of learning in memory in the octopus were premature, unfortunately—they have very complex brains, … "Octopuses are so brilliant," said author and naturalist Sy Montgomery, who believes their intelligence is almost off the charts. It displays a high level of organization in order to do things like coordinate all of the chromataphores' color changes.
"There are a lot of open questions about how these nodes in the nervous system are connected to each other.".
Yes, Hollywood octopuses have torn down the Golden Gate Bridge, destroyed ships, and feasted on movie stars. I mean, who has grace like this?
Next stop: the beach for another octopus delicacy – crabs.
It is located in its head. A giant Pacific octopus at the New England Aquarium in Boston. "In fact, they're portrayed in movies as aliens," said Reid. "I say, this is one of the most beautiful creatures on this planet, one of the smartest, one of the most interesting, and one of the most alien," Montgomery replied. He's responsible for the care and feeding of the lab's octopuses, and stocks up on their favorite food: tiny grass shrimp. Octopuses only have one true brain, which is located in their head, wrapped around their esophagus.
Play is one of those characteristics of higher minds.". And the grace?
This is not a reflex; this is a decision-making process," Hanlon said. A big part of Murphy's job is keeping Rudy from getting bored. An octopus has one brain. The scientific name Octopoda was first coined and given as the order of octopuses in 1818 by English biologist William Elford Leach, who classified them as Octopoida the previous year.

It was as if she wanted Reid to join her in her octopus' garden. Squid and octopuses have elaborate brains and behaviors, and scientists say studying them in the laboratory could yield important biological insights. "She is powerful," he said. About two thirds are located in its arms. A new model being presented in Bellevue, Washington State, is the first attempt at a comprehensive representation of information flow between the octopus's suckers, arms and brain…
Correspondent Chip Reid said, "Some people go, 'Eeeww, that's creepy.' Octopus brains and vertebrate brains have no common anatomy but support a variety of similar features, including forms of short- and long-term memory, versions of … As such, it's considered not only useful to study them to understand intelligence on Earth, but perhaps as a way to prepare for smart aliens - if that day ever comes. "It is.
The octopus changes its shape, colors, patterns, even the texture of its skin, to look like seaweed, and does it in the blink of an eye.
