To replenish neurons in damaged eye stalks and smell circuits, crayfish simply take cells from their blood and turn them into neurons. New Scientist explains: To do so, they utilise what amounts to a nursery for baby neurons, a little cl

stanley canada are a hundred or so cells in this area. Each cell will split into two daughter cells, precursors to full neurons, both of which migrate out of the niche. Those that are destined to be part of the olfactory system head to two clumps of nerves in the brain

The catch is that crayfish are not exactly humans, which is quite obvious when you stare down at a dinner plate full of them. As invertebrates, they don ;t technically have blood but a fluid called hemolymph that circulates in their body. These cells in the hemolymph that turn into neurons, which called hemocytes, are very different from our red blood cells or hematocytes, despite the similar spellings. Nevertheless, it one of those cool discoveries that shows the value of research into obscure, little creatures. And maybe someday we ;ll be able to steal their super powers.
