This volume provides a thorough review of receptors in the developing nervous system, focusing on those related to neurotransmitters. It puts basic and clinical information into perspective and points to possible areas for future research. The authors take a contemporary approach emphasizing information derived from the application of cell and molecular biology. Volume one discusses receptors related to growth factors and hormones. Together the two volumes will provide an invaluable source of reference for researchers and graduate students in a wide range of basic and clinical disciplines.
