Could these same neurons be used in a sort of "automatic pilot"? This is what Nicolas Franceschini, Franck Ruffier and Jul...

...internal organs, and from orifices like the mouth, eyes or ears. Because of TfR1's essential function in transporting iron into cells, it is found on the surface of virtually every cell of the body. It is abundant on endothelial cells, which line blood vessels, a fact that may help account for the ble...
