As i was reading your presentation, the image came to me of an old commercial of the twins arguing whether a particular brand of mints were candy or a breadth freshener. I don't know if you are old enough to remember it, but the announcer would jump-in and say, "stop, you're both right!". And so, i jump-in, not as confident as that announcer but with a question which may join the idea of NAcc DA as involved in energy expenditure and in reward. Could NAcc DA be involved in mediating a "feeling of energy"?
Cheers,
