Evans and his team have shown that PPAR-delta helps the liver resume its normal function in obese mice. Evans will dis...Scientists find hormone activity explains adolescent mood swings
.... One sub-type, GABA-A receptors containing the delta subunit, such as alpha4-beta2-delta, has the highest sensitivity to steroids. In order to study its role in puberty, the researchers used a mouse model that reliably predicts the human condition. In this rodent model, the alpha4-beta2-delta receptor ...Brain wave changes in adolescence signal reorganization of the brain

..., brain waves are classified from the very slowest delta waves (1-3 oscillations per second) seen in very deep sleep, through theta (4-7 oscillations per second), alpha (8-13 oscillations per second) and beta (14-30 oscillations per second) to the most rapid firings in the human brain - gamma oscillations ...Ecological effects of Gulf Coast hurricanes
