The Timing of Hormone Signals in the Orchestration of Brain Development

  • Paola S. Timiras
Part of the Topics in Developmental Psychobiology book series (TDP)


During development, the entire organism as well as specific organs and systems, including the central nervous system (CNS), undergo so-called critical periods characterized by accelerated growth and differentiation and by great susceptibility to environmental stimuli. Among such stimuli, hormones have been shown to play roles, both organizational (i.e., to direct cell differentiation) and regulatory (i.e., to influence the rate of growth and metabolism in mammals). The most important developmental effects of major hormones are presented in Table I.
