• Recent prospective studies suggest that thyroid state plays a role in affective disorders. A
lack of thyroid hormones can lower the threshold for depression; an excess can contribute to …

This review discusses evidence for neurotransmitters as developmental signals in such
ontogenic processes as neural tube formation (neurulation), germinal cell proliferation, and …

Despite its broad usefulness, lead has been long recognized to be acutely toxic at high‐
dose exposures. This chapter deals with adverse health effects caused by exposure to lead …

The remarkable development of molecular biology has had its counterpart in an impressive
growth of a segment of biology that might be described as atomic biology. The past several …

The potential of ostensibly structurally diverse environmental chemicals to modulate
endocrine processes in biological systems has been recognized. Difficulty in classifying …

TCDD and thyroxine have common molecular reactivity properties which enable them to
present a planar face and lateral halogens in interactions with proteins. These molecular …

Publisher Summary This chapter describes the term critical period that refers to that segment
of neurogenesis when specific ontogenic processes are vulnerable to perturbation by …

SYNOPSIS. The climactic stages of amphibian metamorphosis constitute a period
characterized by radical morphological changes that are driven primarily by the thyroidal …
