New research from the University of Chicago reveals that the nervous system circuitry that controls arm movement in octopuses is segmented.
Octopuses have a massive nervous system, with more neurons combined across the eight arms than in the animal's brain.
Nerves from multiple segments connect to different regions of muscles, suggesting the segments work together to control movement.
