Serotonin initiates and autoamplifies its own synthesis during mouse central nervous system development.

Some cells from cultured embryonic mouse hypothalamus were found to express aromatic-L-amino acid decarboxylase (EC 4.1.1.28) activity and serotonin uptake and storage. These neuron-like cells differed from serotoninergic neurons in cultured embryonic mouse brain stem since they did not contain tryptophan hydroxylase. We studied the effect of the serotonin agonist 8-hydroxy-2-[di-(n-propyl)amin...

Vulnerable periods and processes during central nervous system development.

The developing central nervous system (CNS) is the organ system most frequently observed to exhibit congenital abnormalities. While the developing CNS lacks a blood brain barrier, the characteristics of known teratogens indicate that differential doses to the developing vs mature brain are not the major factor in differential sensitivity. Instead, most agents seem to act on processes that occur...

Prenatal Central Nervous System Development

This chapter provides an overview of the major stages of prenatal central nervous system (CNS) development. CNS development plays the central role in the primary argument of this book. That argument is that the prenatal CNS is particularly vulnerable to environmental perturbations because it is rapidly developing during that time period. Further, we argue that many of the learning and behaviora...
