"""One thing that is remarkable about this book is that no one has tried to produce a similar one before..."" ""...a book, which , to the beginner, is an invaluable source of information and to the experienced researcher is a reliable reminder of many of those things which one once knew but has temporarily forgotten or just neglected to learn."" ""...it is an unprecedented source of basic information and will be an asset to many vision scientists, whether involved at undergraduate level or in frontline research on the visual system."" Brain, 1999"
