• Sommario/riassunto: This book begins with the historical discoveries of the features of the vascular system and its importance in the overall circulatory function. Modern aspects of vascular biology in terms of structure and function are then described, followed by the introduction of physical principles and basic fluid mechanics for quantitative analysis. The hemodynamics of large arteries, the optimal structure of vascular branching and the pulsatile energy transmission and modeling aspects are elaborated. These are extended to analyze the function of the venous system and the microcirculation. Finally, the integrated

• Sommario/riassunto: In The Intelligent Movement Machine: An Ethological Perspective on the Primate Motor System, Michael Graziano offers a fundamentally new theory of motor cortex organization: the rendering of the movement repertoire onto the cortex. The action repertoire of an animal is highly dimensional, whereas the cortical sheet is two-dimensional. Rendering the action space onto the cortex therefore results in a complex patter, explaining the otherwise inexplicable details of the motor cortex organization. This clearly written book invludes a complete history of motor cortex research from its discovery to the present, a discussion of the major issues in motor cortex research, and an account of recent experiments that led to Graziano's "action map view." Though focused on the motor cortex, the book includes a range of topics from an explanation of how primates put food in their mouths, to the origins of social behavior, such as smiling and laughing, to the mysterious link between movement disorders and autism. The book is written for a general audience and should be of interest to experts, students, and the scientific lay.
