The Motoneurone and its Muscle Fibres presents a state-of-the-art summary of knowledge concerning the motoneurones, vital for innervating and commanding skeletal muscles. No muscle action would be possible without motoneurones. These cells are therefore absolutely essential for the execution of normal behaviour and for life support. It is their degeneration that leads to various kinds of motoneurone disease (e.g. ALS) that are often ultimately lethal. However, the study of motoneurones is also important for general insights as to how neurones work, because the motoneurone is probably the best understood kind of nerve cell so far in neuroscience. Motoneurones of the spinal cord were the first type of central nerve cell to be subjected to detailed physiological measurements, and much is known about how their activity is regulated by synapses from other central neurones. For most of the individual neurones within the central nervous system, the precise functional tasks are difficult to define. However, for motoneurones much is now known about their short- and long-term interactions with their main targets, the skeletal muscle fibres. Functions of neurones must be analyzed in relation to the response properties of their target cells. Therefore, this book deals with both, summarizing classical as well as recent knowledge concerning the motoneurone and its muscle fibres. This is the first time that so many aspects of this broad subject matter are treated in one comprehensive monograph.

Colours are increasingly important in our daily life, but how did colour vision evolve? How have colours been made, used and talked about in different cultures and tasks? How do various species of animals see colours? Which physical stimuli allow us to see colours and by which physiological mechanisms are they perceived? How and why do people differ in their colour perceptions? In answering these questions and others, this book offers an unusually broad account of the complex phenomenon of colour and colour vision. The book's broad and accessible approach gives it wide appeal and it will serve as a useful coursebook for upper-level undergraduate students studying psychology, particularly cognitive neuroscience and visual perception courses, as well as for students studying colour vision as part of biology, medicine, art and architecture courses.
