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

“We now have a model cephalopod where we can interrogate biological function at much higher resolution than before.” The nervous system and behavior of coleoid cephalopods (squid, octopus and ...

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 ...

This discovery by researchers at the University of Chicago helps us understand the strange way cephalopods navigate the world, and may even inform future designs for soft robots. "If you're going to ...

“It’s exciting to study cephalopod nervous systems. Octopuses diverged from vertebrates many million years ago and have a very different body plan, so for nervous system structure and ...

Many experts believed that the cephalopod nervous system was not sophisticated enough to understand or process pain. Yet, in recent studies, the opposite seems to be the case. In its recent call ...

In most of a cephalopod’s body, RNA editing doesn’t often affect the makeup of proteins. But in the nervous system, it’s a different story. In longfin squids’ nervous systems, 70 percent ...

Scientists at the Marine Biological Laboratory created an albino strain of bobtail squid (on left) that allows for clear optical viewing of the nervous system in a living cephalopod for research.

"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.
