Long story short: Cephalopods don't have their neurons organized in the same way that we vertebrates do. An octopus has as many neurons as a cat, but instead of relying on a central brain, the octopus' neurons are far more scattered. Some are centralized into what we might think of as a "brain"—in this case, a donut-shaped organ that actually wraps around the octopus' esophagus. But the bulk of the neurons are distributed throughout the octopus' body. When the octopus moves, the centralized and decentralized neurons work together, sharing information and the duties of processing and control*.
Researchers like Hochner think that distributed processing system could make for better robots that can do more thinking on their own. Now, his work is paying off. In the video above, you can see the robotic arm produced by an interdisciplinary, team funded by the European Commission, of which Hochner is a part. The 17-inch arm can grasp objects and is the first step in a larger plan to build an entire robot octopus.
I'll say that again, "Robot octopus." Feel free to squeel with delight.
*For the record, this is my guess for why the technically dead squid in that video Xeni posted on Monday still reacted when doused with soy sauce. Squid have distributed neurons, just like octopuses. So some of its "brain" was dead. But the distributed neurons spread throughout its arms were still, apparently, somewhat functional. In the video, I mentioned that one of the scientists I spoke with told me that the humane way to kill an octopus was to kill the whole octopus at once.
Apple released this lovely new commercial featuring Carl Sagan reading from his magnificent 1994 book Pale Blue Dot: A Vision of the Human Future in Space, now available as an audiobook. This surprising partnership spurred Adweek to interview my friend Ann Druyan, Sagan’s wife, collaborator, and creative director of the Voyager Golden Record, about being […]
The Action Lab took a maglev gyroscope and placed it inside a sealed chamber to see what happens to a levitating gyroscope in a vacuum. A lot of people took issue with the experiment’s setup and explanation, but it’s interesting nonetheless. He responded to those concerns: Hi everyone! I see a lot of comments that […]

As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
The Bragi Dash Truly Wireless Smart Earphones are far more than your run of the mill Bluetooth earbuds. While the earpiece design makes these earbuds ideal for exercise and activity, and passive noise cancelling is conducive to a more serene listening experience, these buds go well beyond just playing music.First of all, they can actually […]
