The axolotl, also known as Ambystoma mexicanum, is an aquatic salamander renowned for its ability to regenerate its spinal cord, heart, and limbs. These amphibians also readily make new neurons throughout their lives. In 1964, researchers observed that adult axolotls could regenerate parts of their brains, even if a large section was completely removed. But one study found that axolotl brain regeneration has a limited ability to rebuild original tissue structure.
