Whereas the cerebral specialization for skilled manual actions (praxis) seems closely linked to dominance for language, with both functions left lateralized in the vast majority of humans, the neural correlates of hand preference are still less well understood. Indeed, as a combination of inherited and non-inherited genomic factors (i.e., direct parental and concealed environmental contributions), handedness – in contrast to language – is less likely to have strong genetic indices and clearly lateralized functional organization. What about eye dominance, unimanual and bimanual object manipulation, and gestures, or attentional systems and the related egocentric or allocentric coding of space? Are these different categories functionally and structurally interconnected? Is their development and contribution to task performance linked, even if they are differently lateralized? How are they connected to language learning or its development? In trying to understand these relationships and their neural underpinnings we obtain a new insight into fundamental human behaviors, which depend either on shared or distinct cerebral resources that must, nevertheless, be harmonized by higher-order cerebral processing. In this Research Topic we assembled a dozen of original research contributions, as well as articles with more theoretically-driven perspectives, that directly speak to these issues. Hopefully this work will serve as a foundation for further discussions and will stimulate new research in this fascinating domain.

The growth of clinical neuropsychology has been unprecedented. This growth has been oriented more toward the provision of than toward the foundation for services. Thus, while a greater number of psychologists are performing a greater number of neuropsychological procedures, there seems to us an uneven parallel growth between these services and the empirical foundations for them. It should come to no one's surprise that increasingly aggressive attacks on the field have been leveled. Despite these attacks, clinical neuropsychology con tinues to enjoy exceptional growth within psychology and acceptance by other health practitioners, insurance companies, legislators, judges, juries, and above all, consumers of our services. Growth without self-reflection is a dangerous enterprise, as is growth without directions. We find it disconcerting that existing and limited "self analysis" has assumed that neuropsychological dysfunction is immune to the same variables that affect psychological dysfunction. Some attention has been paid to the most obvious ones, such as age, but all others have been ignored and/ or misunderstood. This neglect has spawned a body of knowledge replete with questionable data and unfounded conclusions. Hence, it is surprising that clinical neuropsychologists consider themselves to be more scientifically sound than their regular clinical counterparts.

Download PDFDownload EPUB Affordances are meaningful relations between the features of observed objects and the observer's action systems with its proper abilities. The notion of affordance integrates perceptual, cognitive and motor functions, so that perceiving an object, conducting cognitive operations on it, and executing motor actions with it cannot be considered as independent functions. Limb apraxia is a higher-order motor disorder that refers to disturbance of one or more of three domains: imitation of meaningless gestures, pantomime of meaningful gestures, and disturbance of interaction with objects. The first aim of the Research Topic was to put together theoretical and research contributions on affordance mechanisms to highlight their role in explaining apraxia deficits. The second aim was to clarify how studies on apraxia have implications for theories of affordances.

Discussed in this book is the association between speech and movements, especially those of the preferred hand. Both are skilled motor activities that appear to depend upon a similar neural organization that is available in the left hemisphere of the brain. The nature of this association of the cerebral control of speech and skilled manual performance is discussed in four sections: 1. Motor control and speech examines speech as a motor activity2. Language and gesture examines the correspondence between spoken language and manual gesture3. Motor performance and aphasia examines the motor impairments associated with aphasias4. Interactions of speech and manual performance examines the interactions that occur between concurrent verbal and manual activities

Neural Plasticity Across the Lifespan reviews the recent scientific developments which are transforming our understanding of the human brain. For many years it was thought that modifications to the structural and functional organization of the brain were limited to a short early period of life, "the critical period", and, in adults, to the memory system. Recent research suggests that on the contrary we should see the human brain as a flexible structure, which adapts and modifies in response to learning, sensory experience, age and disease. The book provides an integrated overview of contemporary research on neural plasticity - the process by which the brain can change in structure and function to cope with new experiences and react to the effects of acquired damage or sensory deprivation. It reviews data on plasticity in the developing brain, looking at both typical and atypical development, alongside clinical and observational research on the adult population. It covers a number of key topics, including: different forms of neural plasticity factors affecting neural plasticity (ageing and gender), neural plasticity in language acquisition, memory and bodily self-consciousness mechanisms of repair – plasticity following sensory deprivation and acquired brain damage. This is an accessible overview of an emerging field of research which has fundamental implications for how we perceive our potential to change throughout our lives. It will be essential reading for all students of cognitive development, cognitive neuroscience and lifespan development.

First published in 1986. The present volume is the outcome of a symposium on Gestures, Cultures and Communication, held in May 1982 at Victoria College, University of Toronto. This conference, one of a series of five colloquia which took place during the Third International Summer Institute for Semiotic and Structural Studies, was organized by the Toronto Semiotic Circle. The purpose of the 1982 conference was to explore the biological basis of gestures by bringing together investigators working mainly in the fields of anthropology, neurophysiology, neuropsychology and psycholinguistics.

This book has brought together leading investigators who work in the new arena of brain connectomics. This includes ‘macro-connectome’ efforts to comprehensively chart long-distance pathways and functional networks; ‘micro-connectome’ efforts to identify every neuron, axon, dendrite, synapse, and glial process within restricted brain regions; and ‘meso-connectome’ efforts to systematically map both local and long-distance connections using anatomical tracers. This book highlights cutting-edge methods that can accelerate progress in elucidating static ‘hard-wired’ circuits of the brain as well as dynamic interactions that are vital for brain function. The power of connectomic approaches in characterizing abnormal circuits in the many brain disorders that afflict humankind is considered. Experts in computational neuroscience and network theory provide perspectives needed for synthesizing across different scales in space and time. Altogether, this book provides an integrated view of the challenges and opportunities in deciphering brain circuits in health and disease.

Brain asymmetry for speech is moderately related to handedness but what are the rules? Are symmetries for hand and brain associated with characteristics such as intelligence, motor skill, spatial reasoning or skill at sports? In this follow up to the influential Left, Right Hand and Brain (1985) Marian Annett draws on a working lifetime of research to help provide answers to crucial questions. Central to her argument is the Right Shift Theory - her original and innovative contribution to the field that seeks to explain the relationships between left-and right-handedness and left-and right-brain specialisation. The theory proposes that handedness in humans and our non-human primate relations depends on chance but that chance is weighted towards right-handedness in most people by an agent of right-hemisphere disadvantage. It argues for the existence of a single gene for right shift (RS+) that evolved in humans to aid the growth of speech in the left hemisphere of the brain. The Right Shift Theory has possible implications for a wide range of questions about human abilities and disabilities, including verbal and non verbal intelligence, educational progress and dyslexia, spatial reasoning, sporting skills and mental illness. It continues to be at the cutting edge of research, solving problems and generating new avenues of investigation - most recently the surprising idea that a mutant RS+ gene might be involved in the causes of schizophrenia and autism. Handedness and Brain Asymmetry will make fascinating reading for students and researchers in psychology and neurology, educationalists, and anyone with a keen interest in why people have different talents and weaknesses.
