What And Where Is An Octopus’S Mind?, Jennifer A. Mather
What And Where Is An Octopus’S Mind?, Jennifer A. Mather
Animal Sentience
It is gratifying to see the thorough discussion of whether octopuses have a mind, though perhaps a mind that is different from those of “higher” vertebrates. It stimulates us to look at the welfare of these animals and challenges us to find better ways to test mindfulness and cognition across animals with widely differing natural histories and sensory and motor capacities.

Animal Sentience
An octopus has more neurons in their peripheral nervous system (PNS) than in their brain. PNS neurons could participate in forming cognitive networks with the central brain in the same way that the cerebellum is now thought to contribute to mammalian cognition. However, cephalopods lack myelinated fibres, which might decrease the ability of the PNS to participate in cognitive networks. The lack of myelinated fibres may also select for a less integrated brain, with an increased emphasis on local information processing. Alternatively, integration may still occur across distant neural centers, but proceed more slowly in cephalopods than in mammals.
