In this treatise, current knowledge on the neurogenesis, axonal outgrowth, synaptogenesis, and regenerative capacity of descending supraspinal pathways in tetrapods is discussed. Although emphasis is on the clawed toad, Xenopus laevis, chicken embryos, opossums and rodent data, also the data available for primates including man are presented. It will be shown that 1) the outgrowth of descending supraspinal pathways is the result of a coordinated program; 2) the pattern of early descending axonal tracts is similar in all vertebrate groups; 3) the formation of descending supraspinal pathways occurs according to a developmental sequence; 4) the earliest descending supraspinal fibers arrive in a rather immature spinal cord, and 5) the regenerative capacity of descending supraspinal pathways depends on the developmental stage the particular pathways arise.

This Handbook of Brain and Behaviour in Human Development presents up-to-date knowledge on motor development, development of perceptual systems and cognitive development, and development of emotions and communication in relation to the development of the central nervous system. It covers the age range from prenatal stages of development to the onset of adolescence. Recent research and insights with respect to the above-mentioned domains are reviewed and future research directions and perspectives are discussed. The book consists of 5 sections, each edited by separate editors, and each containing a series of 8-12 chapters written by renowned and influential experts. The first section introduces brain and behavioural research in human development from four different points of view. After a discussion of some basic issues in the study of brain-behaviour development, conceptual problems involved in studying behavioural development in relation to early environment, and neuropsychological problems inherent in research into early development and the role of developmental genetics are discussed. The section on structural development contains a short introductory overview of recent trends in research and gaps in our knowledge. The section on motor development contains contributions from investigators of fetal and postnatal motor development in the human as well as contributions on research in experimental animals which have contributed significantly to our knowledge of the development of motor behaviour in the human. An important issue is the possibilities and limitations of extrapolating animal data to human development. Next to `classical' approaches to the study of motor development, contributions using the dynamical systems approach are also included. The section on perceptual and cognitive development discusses the development of cognitive functions in relation to perceptual systems and to the development of the brain. Issues such as the development of the temporal organisation of behaviour, perception and cognition, memory functions and more complex thought processes are covered in this section. The section on the development of communication and emotional development contains contributions to this growing field of interest. Connections between emotional and cognitive development as well as the neural basis of emotional development are core topics. Ethological and psychological approaches to both emotional and communicative development are discussed. The book is aimed at an audience ranging from (developmental) neurologists, movement scientists, (developmental) neurophysiologists and neuroanatomists and molecular biologists to ethologists, biologists and psychologists interested in the development of perceptual, cognitive and emotional functions.

Progress in developmental neurobiology and advances in (neuro) genetics have been spectacular. The high resolution of modern imaging techniques applicable to developmental disorders of the human brain and spinal cord have created a novel insight into the developmental history of the central nervous system (CNS). This book provides a comprehensive overview of the development of the human CNS in the context of its many developmental disorders. It provides a unique combination of data from human embryology, animal research and developmental neuropathology, and there are more than 400 figures in over a hundred separate illustrations.

Connections define the functions of neurons: information flows along connections, as well as growth factors and viruses, and even neuronal death can progress through connections. Accordingly, knowing how the various parts of the brain are interconnected to form functional systems is a prerequisite for properly understanding data from all fields in the neurosciences. Clinical Neuroanatomy: Brain Circuitry and Its Disorders bridges the gap between neuroanatomy and clinical neurology. It focuses on human and primate data in the context of brain circuitry disorders, which are so common in neurological practice. In addition, numerous clinical cases are presented to demonstrate how normal brain circuitry can be interrupted, and what the effects are. Following an introduction to the organization and vascularization of the human brain and the techniques used to study brain circuitry, the main neurofunctional systems are discussed, including the somatosensory, auditory, visual, motor, autonomic and limbic systems, the cerebral cortex and complex cerebral functions. In this 2nd edition, apart from a general updating, many new illustrations have been added and more emphasis is placed on modern techniques such as diffusion magnetic resonance imaging (dMRI) and network analysis. Moreover, a developmental ontology based on the prosomeric model is applied, resulting in a more modern subdivision of the brain. The new edition of Clinical Neuroanatomy is primarily intended for neurologists, neuroradiologists and neuropathologists, as well as residents in these fields, but will also appeal to (neuro)anatomists and all those whose work involves human brain mapping.
