The lamprey, an eel-like primitive vertebrate, is a popular organism for neurobiology studies because it has a relatively simple nervous system. It is of particular interest to those studying spinal cord injury (SCI) because, unlike humans, the lamprey can regenerate nerve connections and recover normal mobility within about 8 weeks following an injury to its spinal cord. With the first reference genome for the lamprey species (Petromyzon marinus) recently completed, this fish is now poised to accelerate research about how the nervous system normally functions and recovers following injury.
