Nervous System Communication
It’s amazing to think how much science, and biology, in particular, has changed over the years. The thoughts and ideas that many scientists had turned out to be way off base. It’s only as things develop that new ideas and theories are introduced. And a similar thing was true with regards to the human nervous system.
Scientists used to think that our nerves sent information electronically to the rest of the body. However, Dr. Otto Loewi proved that it was actually submitted chemically. He had a dream, awoke in the middle of the night, and scribbled what he could remember. In the morning he read over it and realized what he’d written. His idea was later proven true, and he won the 1936 Nobel Prize for it.
