Book Description
This book presents new findings on body image and also introduces new neuroscience-based methods for the fields of neurology and neurorehabilitation. Even when the hand is stationary we know its position – information that is needed by the brain to plan movements. If the sensory input from a limb is removed as the result of an accident, or as part of an experiment with local anesthesia, then a ‘phantom’ limb commonly develops. We used ischemic anesthesia of one limb to study the mechanisms that define this phenomenon. Surprisingly, if the fingers, wrist, elbow, ankle, and knee are extended before and during an ischemic block, then the perceived limb is flexed at the joint and vice versa. Furthermore, the limb is perceived to move continuously with no default position. The key parameter for these illusory changes in limb position is the difference in discharge rates between afferents in the flexor and extensor muscles at a joint. The final position of the phantom limb depends on its initial position, suggesting that a body image uses incoming proprioceptive information for determination of starting points and endpoints when generating movements. In addition, the change in position does not involve limb postures that are anatomically impossible, suggesting that illusory posture is constrained by body maps. These results provide new information about how the brain generates phantom limbs.

Book Description
This book explores the fascinating area of interpersonal coordination in force production tasks, outlining the author’s extensive research to date and presenting stimulating new perspectives. The purpose is to provide a detailed exposition of current understanding of the science behind interpersonal joint action. Readers will find clear explanation of concepts from social cognition and neuroscience that are key to an understanding of the field, including the social brain hypothesis, the mirror neuron system, and joint action, as well as other relevant background information. The author then proceeds to present an overview of recent original studies on interpersonal movement coordination performed at his laboratory in Japan. These studies provide insights into such issues as complementary and synchronous force production in joint action, bidirectional transfer between joint and solo actions, and motor control hierarchy in joint action involving bimanual force. They also set the direction for integration of knowledge of physical properties and social cognition. The book will be of interest for researchers and graduate students in all areas of the biomedical sciences.

Book Description
Implement TMR with Your Patients and Improve Their Quality of Life Developed by Dr. Todd A. Kuiken and Dr. Gregory A. Dumanian, targeted muscle reinnervation (TMR) is a new approach to accessing motor control signals from peripheral nerves after amputation and providing sensory feedback to prosthesis users. This practical approach has many advantages over other neural-machine interfaces for the improved control of artificial limbs. Targeted Muscle Reinnervation: A Neural Interface for Artificial Limbs provides a template for the clinical implementation of TMR and a resource for further research in this new area of science. After describing the basic scientific concepts and key principles underlying TMR, the book presents surgical approaches to transhumeral and shoulder disarticulation amputations. It explores the possible role of TMR in the prevention and treatment of end-neuromas and details the principles of rehabilitation, prosthetic fitting, and occupational therapy for TMR patients. The book also describes transfer sensation and discusses the surgical and functional outcomes of the first several TMR patients. It concludes with emerging research on using TMR to further improve the function and quality of life for people with limb loss. With contributions from renowned leaders in the field, including Drs. Kuiken and Dumanian, this book is a useful guide to implementing TMR in patients with high-level upper limb amputations. It also supplies the foundation to enable improvements in TMR techniques and advances in prosthetic technology.

Book Description
Neuroscientist V.S. Ramachandran is internationally renowned for uncovering answers to the deep and quirky questions of human nature that few scientists have dared to address. His bold insights about the brain are matched only by the stunning simplicity of his experiments -- using such low-tech tools as cotton swabs, glasses of water and dime-store mirrors. In Phantoms in the Brain, Dr. Ramachandran recounts how his work with patients who have bizarre neurological disorders has shed new light on the deep architecture of the brain, and what these findings tell us about who we are, how we construct our body image, why we laugh or become depressed, why we may believe in God, how we make decisions, deceive ourselves and dream, perhaps even why we're so clever at philosophy, music and art. Some of his most notable cases: A woman paralyzed on the left side of her body who believes she is lifting a tray of drinks with both hands offers a unique opportunity to test Freud's theory of denial. A man who insists he is talking with God challenges us to ask: Could we be "wired" for religious experience? A woman who hallucinates cartoon characters illustrates how, in a sense, we are all hallucinating, all the time. Dr. Ramachandran's inspired medical detective work pushes the boundaries of medicine's last great frontier -- the human mind -- yielding new and provocative insights into the "big questions" about consciousness and the self.

Book Description
The phenomenon of phantom limb was described in medical literature at least as early as 1545 by Ambroise Pare, according to the notes in the translation of Lemos' dissertation, "On the Continuing Pain of an Amputated Limb", by Price and Twombly [9]. This strange experience was brought to public attention by a popular essay anonymously published 1866 by Mitchell concerning the story of George Dedlow, a quadriamputee who described his invisible limbs [7]. In 1871 Mitchell wrote under his own name, and was the. first to use the term "phantom limb" [8]. In this work, he also corrected some erroneous beliefs that had arisen from his 1866 essay [13]. Most amputees report feeling a phantom limb almost immediately after amputation of an arm or a leg [11]. It is a positive sensation, usually described as tingling or numbness, which is not painful. The most distal parts of the limb, particulary the digits, thumb, and index, are the strongest and most persisting phantom sites, and may be the only parts to appear even after removal of a whole limb. The elbow or knee is sometimes involved, the forearm or lower leg rarely, and the upper arm and thigh almost never [5]. The phantom thus appears to consist predominantly of those parts which have the most extensive representa tion in the thalamus and in the cerebral cortex.
