A rich source of information about human voluntary movement in health and disease can be found in this book. The most esteemed researchers in their respective fields bring you up-to-date articles. Their collected work combines fundamental research in the life sciences with clinical neuroscience in a unique overview. The interdisciplinary aspects of motor physiology uncover a wealth of information for researchers from neighboring disciplines. For example, oculomotor research, vestibular research, equilibrium, sensory research and cognition, evolution, synaptic and elementary processes and the neurological sciences can be discovered.

The hand is an organ of considerable capability. With it we feel, point, and reach, we determine the texture and shape of objects we palpate, we emit and receive signs of approval, compassion, condolence, and encouragement, and, on a different register, rejection, threat, dislike, antagonism, and attack.

Vernon Mountcastle has devoted his career to studying the neurophysiology of sensation--the extended sensory surface, consisting of skin and subcutaneous tissue--in the hand. In "The Sensory Hand" Mountcastle provides an astonishingly comprehensive account of the neural underpinnings of the rich and complex tactile experiences evoked by stimulation of the hand. Mountcastle focuses attention on the nerve pathways linking the hand to central neural structures, structures that play a role in several other aspects of somatic sensation. His new book thus becomes a sequel to his earlier volume, "Perceptual Neuroscience," in which he offered a detailed analysis of the role of the distributed systems of the neocortex in perception generally.

Written by one of the giants of modern neuroscience and the first single-authored book-length treatment of the subject, "The Sensory Hand" is a major work of scholarship that will be essential reading for anyone interested in how the brain registers sensation and perception.

A proposal by two eminent biological scientists for a mechanism whereby mind becomes manifest from the operations of brain tissue. This significant contribution to neuroscience consists of two papers, the first by Mountcastle an, the second by Edelman. Between them, they examine from different but complementary directions the relationships that connect the higher brain-memory, learning, perception, thinking-with what goes on at the most basic levels of neural activity, with particular stress on the role of local neuronal circuits.Edelman's major hypothesis is that "the conscious state results from phasic reentrant signaling occurring in parallel processes that involve associations between stored patterns and current sensory or internal input." This selective process occurs by the polling of degenerate primary repertoires of neuronal groups that are formed during embryogenesis and development. Edelman's theory extrapolates to the brain the selectionistic immunological theories for which he was awarded the 1972 Nobel Prize in Physiology or Medicine. Mountcastle's paper reviews what is known about the actual structure of various parts of the neo cortex. He relates the large entities of the neocortex to their component modules-the local neuronal circuits-and shows how the complex interrelationships of such a distributed system can yield dynamic distributed functioning. There are strong conceptual parallels between Mountcastle's idea of cortical columns and their functional subunits and Edelman's concept of populations of neurons functioning as processors in a brain system based on selectional rather than instructional principles. These parallels are traced and put into perspective in Francis Schmitt's Introduction.
