Biological Waves: Single Species Models,wave of chemical concentration or mechanical deformation. Looking at almost any film of a developing embryo it is hard not to be struck by the number of wave-like events that appear after fertilisation. There are, for example, both chemical and mechanical waves which propagate on the surface of many

Neural Models of Pattern Formation,recognition and the transmission of visual information to the brain. This is a vast field of study. In this chapter we give only an introduction to some of the models, involving nerve cells, which have been proposed as pattern generators. Basic to the concept of neural activity is the nerve cell, or

Mechanical Models for Generating Pattern and Form in Development,. Pattern generation models are generally grouped together as morphogenetic models. These models provide the embryologist with possible scenarios as to how pattern is laid down and how the embryonic form might be created. Although genes of course play a crucial role in the control of pattern formati
