Human brains are also remarkably like rat brains which is one of the
reasons why most neuroscience research is done on rats. Because rats and
dogs are macrosmatic most visual neuroscience is done on frogs, cats or
small primates. The key point to appreciate is that there are remarkable
homologies between all higher animals when it comes to central nervous
system anatomy and function and this is true not just of the mammals.
The environment has shaped these homologies and differences just as it
continues to shape behaviour. One has to look to homologies in
anatomical structure and environmental pressures to understand
brain-behaviour relations.
