CONCH DING REM \KKS 



This presentation of some aspects of disturbed 

 neural function in the presence of congenital anoma- 

 lies in vertebrates was aimed to show that the abnor- 

 malities are .1 product of the developmental processes 

 and that they may appear in .1 wide range of forms 

 with ultimate expressions at the muss structural, 

 physiologic or biochemical level. They may appear 

 at am stage of development for development spans 

 the life of the organism. An extraordinary variety of 



mechanisms ma) be involved in the processes that 

 lead to the malfunction, extending from patterns 

 that are primarily the result of uncomplicated genetic 

 situations to destructive accidents to the embryo, 

 neoplasia and bizarre variations in chromosomal 

 ploidy. The analysis and description of neurophysio- 

 logy disorders as the) appear in the end stages of 

 anomalous developmental processes may be quite 

 accurate and scientific, but an understanding of how 

 the) ma) have evolved makes the analysis much 

 more rewarding.
