This unit deals with the development and mature organisation of the nervous system in a wide range of animals. The unit examines the complex wiring of the brain and how this organisation relates to an animal's behaviour, ecology and environmental needs. As examples, the unit includes studies of deep-sea fish and those birds and mammals which span the aquatic and terrestrial habitats. Animals with highly specialised senses, such as owls, are also considered. The unit provides a unique perspective of neuroscience—students gain a non-human centric view of the central nervous system and acquire a better understanding and appreciation for brain variation and adaptation across the animal kingdom. The laboratory classes provide practical experience in the examination of the nervous system and instruction in methodology and experimental design.
