Thoughts About the Brain

Rodolfo Llinas.jpg

“Basically there are two types of animals: animals, and animals that have no brains; they are called plants. They don’t need a nervous system because they don’t move actively, they don’t pull up their roots and run in a forest fire! Anything that moves actively requires a nervous system; otherwise it would come to a quick death.”           

–Rodolfo Llinas (Colombian-born Neuroscientist and Thomas and Suzanne Murphy Professor of Neuroscience and Chairman of the department of Physiology & Neuroscience at the New York University, 1934-)
