What do you need to evolve, as a large animal, for your front end to talk to your back end? Why, spindle neurons, of course! These neurons are called spindle neurons because they are long and skinny, perfect for sending messages across a giant animal. Without them, we might still be teeny little organisms zapping signals via a nerve net! Purchase this spindle neuron necklace for yourself or for a friend. It’s makes a great gift for neurologists, spine specialists, large animal vets, and starry-eyed pre-med students.
