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.
The EVATAR is a working model of a reproductive system made from a mouse ovary and bits of a human uterus, cervix, vagina, fallopian tubes, and liver. Developed by Northwestern University researcher Teresa Woodruff and her colleagues, the EVATAR is intended to help better test the effects of medicines and toxins on women. And now […]
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
What could be more fun than a slingshot that shoots tiny airplanes? A slingshot that shoots tiny glowing airplanes of course! These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
