Santiago Ramón y Cajal's work led to hypotheses about nervous system structure, neuroplasticity, and the failure of mammalian central nervous system neurons to regenerate.

“Santiago ramoni kahal the greatest neurobiologist of all time that's right it was named after after him he actually has I think it's like in the second volume of his classic uh book on the uh histology of the nervous system one of the last figures talks about like the inovation of the v in the in the intestine so I'm beautiful for those that don't know kahal shared the Nobel Prize with Camilo Gogi in 1906 they together developed tools and and mapped the structure of the nervous system and and it's fair to say that kahal had Supernatural levels of insight into the nervous system he looked at the nervous systems of so many different animals in dead specimens the the joke even though it's not funny is that many animal species entered his laboratory very few walked out but by looking at fixed specimens under the microscope and then drawing them in you know select elements within them essentially came up with most of the major hypotheses about how the nervous system works not just its structure but neuroplasticity the failure of of mamalian central nervous system neurons to regenerate this is why after traumatic brain injury or stroke there's often loss of function that doesn't recover sometimes it recovers but and people who have injuries younger and can recover certain functions everything from the direction of electrical flow through the nervous system all from looking at tissue that was not alive no electrophysiology no behavioral experiments just just raw but incredible Supernatural seemingly levels of intuition and insight amazing”
