Though coordinating eight separate arms might seem a tricky task for an octopus brain, whats really demanding is controlling the arms flexible, infinitely variable movements. Now researchers have figured out part of their secret.
Unlike us, specific regions of an octopus motor cortex dont correspond to specific parts of its body. Instead, each region controls different parts at different times. Their motor neural network seems as flexible as their bodies a phenomenon that expands the range of neurophysiological possibility, and could refine the design of arm-flexing robots.
