There is controversy about whether axotomized neurons undergo death or only severe atrophy after spinal cord injury (SCI) in mammals. Lampreys recover from complete spinal transection, but only about half of the severed spinal-projecting axons regenerate through the site of injury. The fates of the unregenerated neurons remain unknown, and until now death of axotomized spinal-projecting neurons has not been described in the lamprey brain. We now report that in animals allowed to survive for 12… CONTINUE READING
