In the late 50s Michel Jouvet discovered the presence of muscle atonia during REM sleep in cats and created the first model of REM sleep behavior disorder. He built and led in Lyon, France, the "Laboratory of Molecular Dream Science" (a merry oxymoron to silently protest against the research policy of favoring molecular biology over physiology), where in the late 80s, you could cross people who had worked on sleep in the python, tench fish, tortoise, iguana, hen, lamb, mouse, rat and cat. This brilliant physiologist was also a great storyteller with a very good sense of humor. He supported the theory that dreaming is equivalent to REM sleep (which he called "paradoxical sleep"), kept his own dream diary, and imagined that the ponto-geniculo-occipital waves during REM sleep could compose the song sheet of dreams. He wrote several books published in French on dreams and dreaming.
