Lampreys are jawless vertebrates that diverged from all other vertebrates over 500 million years ago. These animals have become a popular model for examining regeneration of the central nervous system due to the large size of their neurons and robust regenerative capacity.In this issue (pp. 174–182) H. R. Katz, K. E. Fouke, N. A. Losurdo, and J. R. Morgan examine recovery of the burrowing behavior after a complete spinal transection in the larval sea lamprey, P. marinus. Previous work showed that after spinal transection, larval lampreys are completely paralyzed below the injury site; but over the course of 11 weeks post-injury, they gradually regain their ability to swim. Here, the authors show that, similar to swimming behavior, the animals also recover their ability to burrow, albeit with some deficits at 9–11 weeks post-injury. The recovery of these two distinct locomotor strategies highlights the robustness of the neuronal regeneration in the lamprey central nervous system.Credits: Image from the Biodiversity Heritage Library, contributed by the MBLWHOI Library (http://www.biodiversitylibrary.org).
