If left untreated, the infection can lead to severe heart, joint and nervous system problems. While there are vaccines for ...

The octopus is unlike any other creature on Earth. With three hearts, blue blood, a decentralized nervous system, and the ability to change color and texture instantly, it’s no wonder scientists often ...

To perform these processes and others, like crawling or exploring, octopuses rely on their complex nervous system, one that ...

“If you're going to have a nervous system that's controlling such dynamic movement, that's a good way to set it up,” said Clifton Ragsdale, Professor of Neurobiology at UChicago and senior author of ...

“If you’re going to have a nervous system that’s controlling such dynamic movement, that’s a good way to set it up,” said Dr. Clifton Ragsdale, professor of neurobiology at the University of Chicago.

"We think it's a feature that specifically evolved in soft-bodied cephalopods with suckers to carry out these worm-like movements." The octopus nervous system is among the most unusual on Earth.

The fine control these almost-alien animals have over each of their eight arms is at least partially down to the segmentation of the nervous system circuitry that governs it. This discovery by ...

The study, "Neuronal segmentation in cephalopod arms," was published January 15, 2025, in Nature Communications. Each octopus arm has a massive nervous system, with more neurons combined across ...
