REGULATION OF BODY WEIGHT is a complex and dynamic process. Many aspects of this regulation have been addressed by recent publications in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology. Among them are delineation of pathways signaling satiation; interactions with other physiological control systems, notably cardiovascular and reproductive systems; explorat...
