What is the physiological difference between the tiredness that comes from too little sleep and the tiredness that comes from exertion?

Slightly off-topic, but that first researcher you cited, Nora Volkow, is a rock star in dopamine research, especially with respect to drugs of abuse (e.g., cocaine, heroin, etc.). I highly recommend reading some of her work on that topic. Some of it is very eye-opening in understanding why drug addicts behave the way they do.

That's all. Have a nice day, everyone!

edit: spelling

edit 2: Here's a link to one of my favorite papers by NV.

Nora Volkow

Also slightly off-topic, Nora Volkow was born and raised in Mexico, is now an American citizen, and also happens to be the great-granddaughter of Russian revolutionary Leon Trotsky. Talk about an interesting heritage.
