<<Do you have a link that explains the T3 and T4>>
Basically, the thyroid hormones consist of a tyrosine molecule with iodine molecules attached to them. If 4 iodine molecules are attached, you have T4...3 iodine molecules - T3. Its T3 thats required at the cellular level (and especially in the brain). Most of the T3 comes from conversion from T4, which occurs mostly in the liver and kidneys.
A search on t4 t3 conversion will generate a ton of info that will keep you reading for a while. You also might find some interesting results from a search on triiodothyronine (T3)cognition mood .Heres a decent overview of Hypothyroidism... includes a good outline of the thyroid hormones, T4, T3 conversion, interplay between thyroid, hypothalamus and pituitary glands, etc.: http://www.salugenecists.com/genpage.php?tname=disease&dbid=21
