Figure 7: Graphical overview of the processes occurring following octopus pallial nerve lesion.

Hemocytes are involved in scar formation between nerve stumps; they actively proliferate in LL three days post injury. Regenerating fibers are found in the central stump, growing in several directions. Seven days after lesion fibers are able to grow across the scar toward the peripheral stump. Many connective tissue cells proliferate inside the nerve. A spike-like structure forms two weeks post injury in the central stump, due to connective tissue guide. In the peripheral stump, so far showing mainly axon degeneration, bundles of regenerating axons appear, enveloped by new forming connective tissue. See text for details.
