In other related studies, the participation of LHRH, NPY, and other peptidergic cell groups in homeostaticgonadal feedback mechanisms and photoperiodic regulation of the reproductive axis are also being examined. A long-term goal of this laboratory is to understand how these neuropeptidergic systems can coordinate several neural and endocrine activities to produce an appropriate homeostatic state, such as reproductive competency. It is also hoped that our studies may ultimately provide useful information in the treatment of some forms of infertility and in the development of new contraceptive strategies. Levine JE 1997 New concepts of the neuroendocrine regulation of gonadotropin surges in rats. Ph.D. Emory University, Atlanta, Georgia T he Laboratory for Human Biology Research is located within the Anthropology Department, and supports a range of projects investigating issues related to human health, growth and development, stress, reproductive ecology, energetics, and body composition.
Current projects involve research in Samoa, Kenya, Bolivia, Siberia, and the Philippines.
Analysis of saliva and urine samples is also supported. The laboratory is committed to using these methods to facilitate collaborative, population-based research into the relationships between humans and their environments around the world.
