mollusks including cephalopods like octopuses: âDesigning Brains for Pain: Human to Molluscâ by Key and Brown, in which the authors argue these animals lack higher-order âobserver neural networksâ which predict the states and processing of the lower networks.
insects: âIs it pain if it does not hurt? On the unlikelihood of insect painâ by Adamo (which RPâs Invertebrate Sentience Table page cites), with a short article by Adamo on this work here. From the abstract: âInsect nociception is processed largely in parallel in two higher-order areas in the brain: the mushroom bodies and the central complex. There is little evidence of a coordinated pain network that would integrate these two areas with each other along with other traits thought to be important for a pain experience in humans.â. Max Carpendale interviewed Adamo on this topic, and there are more references there.
