Summary: Researchers explored the nervous system of octopuses to understand how they coordinate eight arms and hundreds of suckers.
Abstract: Have you ever tried patting your head and rubbing your stomach simultaneously? Coordinating two arms at the same time can be difficult. So imagine if you had eight arms, like an octopus! The nervous system helps animals coordinate their movements. It also helps them sense and respond to their environment. Each type of animal has a nervous system that is organized differently.
We wanted to know how the octopus's nervous system is organized. To find out, we looked at the nerves inside octopuses’ arms. We found that the main nerve cord in each octopus arm has segments. These segments can communicate with each other. They are also linked to individual suckers. This helps octopuses make large, smooth movements, like swimming. It also helps octopuses make tiny targeted movements, like moving a single sucker. So, the layout of the nerves in the arms tells us how octopuses make such complex movements!
