Which scientist became infamous for studying sensory nerve regeneration by experimenting on himself?

The scientist infamous for studying sensory nerve regeneration by experimenting on himself is Santiago Ramón y Cajal. He was a Spanish neuroscientist and pathologist known for his pioneering work on the structure of the nervous system. Cajal's experiments included not only observations of neural structures but also personal investigations into the regeneration of nerves. His research laid the foundational principles for neuroanatomy and neurophysiology, earning him the Nobel Prize in Physiology or Medicine in 1906. His efforts to understand how nerves could regenerate and heal contributed significantly to our understanding of the nervous system and influenced future research in neuroscience.
