for developmental neurobiologists because, as the editor says in his pre- 

 face, "In many ways problems of circuit remodeling in the mature nervous 

 system are analogous to those seen in the development of neuronal circuitry 

 during ontogeny" . The book reflects the fact that this field of neurobiol- 

 ogy is a very new one; the various contributions are rather disconnected 

 and many contributors stress the tentative nature of their reflections. 



The 13 chapters are well-organised and up-to-date, in-depth reviews, some 

 broad in scope but others largely restricted to the authors' own recent 

 experimental research. They deal with a large variety of systems: para- and 

 sympathetic ganglia, spinal cord, various brain regions, regenerating axons, 

 most of them studied in mammals but some in lower vertebrates. The tech- 

 niques employed vary from anatomy to biochemistry. A central theme in many 

 contributions is "synaptic remodelling", also called "reactive synaptogene- 

 sis" . 



The book is beautifully produced and illustrated with a profusion of ex- 

 cellent line drawings and light and electron micrographs.

Critical review of experimental studies from 1920's onwards; conclusion: 

 "The weight of evidence supports a specific inductive role for the notochord 

 and spinal cord whose absence cannot be compensated for in vivo but for which 

 substitutes exist in vitro"; literature up to date until 1976.
