Society for Neuroscience 2023 Conference Presentation:
Octopus arms show autonomous sensorimotor processing like the vertebrate spinal cord; however, the underlying circuitry is less well-known. Notably, isolated arms show much original behavior, like precise orienting of suckers to chemotactile stimuli, grasping and recruitment of neighboring suckers, bending of the arm, and still more complex movements. We have developed simple interactive arm models with a lateral inhibitory network for sucker circuitry and a serially central pattern generator (CPG)-based network for inter-segmental connections of the arm.
