J. M. ORDY and K. R. BRIZZEE, eds. 1975. NEUROBIOLOGY OF AGING, an inter- 

 disciplinary life-span approach 



Plenum, New York, etc. Advances in Behavioral Biology vol. 16. X, 603 pp., 164 figs., 

 47 tabs., subject index. $ 39.00, £ 17.25 



In so far as development, maturity and aging are integrated aspects of the ontogenetic 

 programme, this book may be of interest to developmental biologists. It is an interdisci- 

 plinary undertaking by 30 American, two Canadian, and two Czech authors. 



The 25 chapters are short to medium-length reviews covering theoretical aspects, 

 methodology, psychophysiology, neurophysiology, neurochemistry, morphology, envi- 

 ronmental factors, and neuropathology. We specifically mention a comprehensive review 

 on the relation of development and aging by Schjeide (48 pp.), and a chapter by Davis 

 and Himwich on the neurochemistry of the developing and aging brain (30 pp.). The final 

 chapter by Ordy deals specifically with non-human primates. 



The book is produced in offset print and has good light and electron micrographs.

For two decades the author of this monograph has headed an extremely active group 

 working (among other things) on skin morphogenesis, mainly in the chick embryo. This 

 work is essentially of an experimental-morphological nature and forms the nucleus of the 

 book, but the available data on mammalian and reptilian skin are well integrated with the 

 avian data. The material is set out with great clarity. Cutaneous gland development and 

 pigmentation were deliberably left out. The cell and tissue interactions in adult skin are 

 duly considered but there are no data on wound healing and regeneration. 



Chapter 1 reviews the essential morphological features of amniote skin development. 

 Then follow chapters on cell proliferation and cell differentiation and their control by 

 intrinsic and extrinsic factors and by dermo-epidermal interaction. The last chapter is 

 devoted to morphogenesis and successively deals with histogenesis, morphogenesis of 

 single cutaneous appendages, and pattern formation (in chick skin mainly). 



The book is profusely illustrated with good line drawings and photo(micro)graphs; of 

 the latter most are originals from the author's laboratory or from other workers. There is 

 a bibliography of some 300 titles which runs until late 1973.
