The neurons in the octopus's arms are concentrated along an axial nerve cord that undulates down the length of each arm, with nodes centered around each of the suckers. It seems complex and focused, and a team led by neuroscientist Cassady Olsen wanted to study it in detail to see if they could learn more about how it functions.

Never challenge an octopus to a popping and locking dance off, that’s what my grandad always said. With eight worm-like arms, they exhibit extraordinary dexterity and control, and now scientists have uncovered a curious feature of their nervous systems that makes it possible.

New research from the University of Chicago revealed that the nervous system circuitry that controls arm movement in octopuses is segmented, giving these extraordinary creatures precise control across all eight arms and hundreds of suckers to explore their environment,

One of the most striking things about these creatures, however, is the fact that each of their eight arms almost seems to have a mind of its own, allowing an octopus to multitask in a manner that humans can only dream about.

A fascinating study found that the prehensile arms of an octopus are segmented from the rest of the cephalopod's body.

A study from the University of Chicago has revealed a critical mechanism in the octopus's nervous system that allows for exceptional movement in its eight arms and hundreds of suckers. The study describes the complex neural circuitry of the octopus arm, which is much more complicated than that found in any other animal.

Chicago, United States - January 15, 2025 New research from the University of Chicago has uncovered how octopuses control their extraordinary arm movements with a segmented nervous system, providing them with unparalleled precision.
