The following information is lifted from a publication titled Green Tea and Human Health, page 30. It's a pamphlet that was written by Dr. Itaro Oguni, Prof. of Food Science, Dept. of Food and Nutritional Sciences, University of Shizuoka, Hamamatsu College. This pamphlet came to me recently via a Den's tea order. No references are cited for this particular information.

Brain chemistry and tea. What a combo! I'm suprised that this thread hasn't brought out our chemistry enthusiasts. I remember being quite struck by the mood altering effect of green tea when I first started to drink it. Now I notice it less. Probably because my baseline mind/body is now more in line with the state of mind that drinking tea helped to produce in the first place. It's official - I have tea brain.
Ugh, the woes of being a tea head, eh murrius? lol

ALL teas Black, white, green, yellow, red etc contain the magic ingredient.
