    Nervous system communication

    In the early 20th century, scientists thought our nerves transmitted information electrically. After a dream, Dr. Otto Loewi awoke during the night and scribbled some thoughts on a paper. Upon waking in the morning, he realized he had written about information being transmitted chemically, later proven to be true and winning him the Nobel Prize in 1936.
