Neurophysiology Discuss the roles of development learning and evolution in the construction of the nervous system The nervous system is responsible for the initiation, propagation and co-ordination of animal behaviour. How it is constructed and what factors are involved encompasses many fields of biology, from ethology and neurophysics to evolution. In this essay I will describe the roles of development learning and evolution in the construction of the nervous system and give experimental evidence that backs up these theories. Evolution Evolution deals with the origins of the nervous system, where it comes from determines how it will be constructed. This will have direct consequences on the relative fitness of an individual as the layout of the nervous system relates to how the animal behaves. Phylogeny is very important therefore to analyse how changes in the nervous system relate to the evolution of behaviour. The only realistic way of studying the evolution of nervous...
