They can regenerate an entire body, including a brain, within 5 days after amputation from a small piece of the body in which no brain tissues remain.n the first study on the organization of the planarian brain, a homolog of the homeobox-containing gene Orthopedia (Otp) from planaria, Djotp, was isolated.
