These animals possess the remarkable ability to heal and regenerate a variety of different tissues 5, 6, 7. Similar content being viewed by othersĬephalopod molluscs are known for the richness and plasticity of their behavioral repertoire and underlying neural control 1, 2, 3, 4. ![]() Injured axons are able to quickly re-grow thus to restoring structure and function. Connective tissue is involved in driving regenerating fibers in a single direction, outlining for them a well-defined pathway. Hemocytes appear involved in debris removal and seem to produce factors that foster axon re-growth. This injury induces scar formation and activates the proliferation of hemocytes which invade the lesion site. To better understand the mechanism of recovery following nerve injury in this species we investigated the process of axon regrowth and nerve regeneration after complete transection of the Octopus pallial nerves. ![]() Cephalopod molluscs, and in particular Octopus vulgaris, are well known for their capacity to regenerate their arms and other body parts, including central and peripheral nervous system. In mammals complete regeneration is often unsuccessful, while most of the low phyla animals can re-grow many parts of their body after amputation. Regeneration is a process that restores structure and function of tissues damaged by injury or disease.
