ABSTRACT
Adaptation to a new environment needs an information system that first informs the body of the characteristics of the environment and second triggers biological responses, which may be more or less ‘‘adaptive’’ to new environmental conditions. The nervous system and the endocrine (or neuroendocrine) system are where the perception and the adaptive processes occur. This chapter will review what we know to date about the effects of high-altitude hypoxia on the endocrine system.
