Brain regeneration: Crayfish turn blood into neurons

Fascinating idea. Whom is going to research this to see if this could be translated to humans? A great stroke association would create an RFP for researchers to respond to with how they would solve the problem and the cost for that.

Think crayfish and you probably think supper, perhaps with mayo on the side. You probably don't think of their brains. Admittedly, crayfish aren't known for their grey matter, but that might be about to change: they can grow new brain cells from blood.

Humans can make new neurons, but only from specialised stem cells. Crayfish, meanwhile, can convert blood to neurons that resupply their eyestalks and smell circuits. Although it's a long way from crayfish to humans, the discovery may one day help us to regenerate our own brain cells.
