As one of the first cortical areas to be explored experimentally, the motor cortex continues to be the focus of intense research. Motor Cortex in Voluntary Movements: A Distributed System for Distributed Functions presents developments in motor cortex research, making it possible to understand and interpret neural activity and use it to reconstruct movements. Featuring viewpoints based on monkey and human studies, the book focuses on how neuronal activity changes during learning, discusses what the motor cortex encodes for, and covers the neuronal representations of voluntary movements and the mechanism of their generation during learning. Section 1 uses functional neuroanatomy and imaging studies to describe motor cortical function, and Section 2 provides an overview of studies about neural representations in the motor cortex. The third section concentrates on motor learning, and the final section highlights the reconstruction of movements using brain activity. Revealing many exciting applications of this rapidly expanding science, this book enhances our understanding of the generation of motor commands. It is an essential resource for neuroscientists interested in motor function, rehabilitation medicine practitioners, and biomedical engineers.

This book highlights some of the main lines of research in cognitive psychology in the Alps-Adria region, which, being geographically located in the centre of the European continent, encompasses eleven regions from six different countries: namely, Austria, Croatia, Hungary, Italy, Serbia and Slovenia. The reason for bringing together authors from different geographical areas and with different approaches to the broad discipline defined as Cognitive Science is detailed in the first section of this book, which outlines a brief history of psychology in each country in the region and provides an overview of the spirit that characterizes the Alps-Adria working community. The Alps-Adria Rector Conference “believes that harmonious coexistence and efficient collaboration of the peoples and communities of the different regions constitute the characteristics and specificities of the present cultural landscape of the Alps-Adria region in Europe.” It is in this spirit that this book has been edited, underscoring the concept of unity in diversity that has characterized the Alps-Adriatic community. Furthermore, such unity is now a necessary attribute for science, where interdisciplinarity is both highly encouraged and increasingly accepted. The second and third sections of the book are devoted to situating this interdisciplinarity in the framework of cognitive science. As such, this book will serve as a basis for fruitful exchange not only inside the community, but also beyond both geographical and theoretical borders.

The study of how the brain processes temporal information is becoming one of the most important topics in systems, cellular, computational, and cognitive neuroscience, as well as in the physiological bases of music and language. During the last and current decade, interval timing has been intensively studied in humans and animals using increasingly sophisticated methodological approaches. The present book will bring together the latest information gathered from this exciting area of research, putting special emphasis on the neural underpinnings of time processing in behaving human and non-human primates. Thus, Neurobiology of Interval Timing will integrate for the first time the current knowledge of both animal behavior and human cognition of the passage of time in different behavioral context, including the perception and production of time intervals, as well as rhythmic activities, using different experimental and theoretical frameworks. The book will the composed of chapters written by the leading experts in the fields of psychophysics, functional imaging, system neurophysiology, and musicology. This cutting-edge scientific work will integrate the current knowledge of the neurobiology of timing behavior putting in perspective the current hypothesis of how the brain quantifies the passage of time across a wide variety of critical behaviors.

Neuro Motor Control And Feed Forward Models Of Locomotion In Humans

Locomotion involves many different muscles and the need of controlling several degrees of freedom. Despite the Central Nervous System can finely control the contraction of individual muscles, emerging evidences indicate that strategies for the reduction of the complexity of movement and for compensating the sensorimotor delays may be adopted. Experimental evidences in animal and lately human model led to the concept of a central pattern generator (CPG) which suggests that circuitry within the distal part of CNS, i.e. spinal cord, can generate the basic locomotor patterns, even in the absence of sensory information. Different studies pointed out the role of CPG in the control of locomotion as well as others investigated the neuroplasticity of CPG allowing for gait recovery after spinal cord lesion. Literature was also focused on muscle synergies, i.e. the combination of (locomotor) functional modules, implemented in neuronal networks of the spinal cord, generating specific motor output by imposing a specific timing structure and appropriate weightings to muscle activations. Despite the great interest that this approach generated in the last years in the Scientific Community, large areas of investigations remain available for further improvement (e.g. the influence of afferent feedback and environmental constrains) for both experimental and simulated models. However, also supraspinal structures are involved during locomotion, and it has been shown that they are responsible for initiating and modifying the features of this basic rhythm, for stabilising the upright walking, and for coordinating movements in a dynamic changing environment. Furthermore, specific damages into spinal and supraspinal structures result in specific alterations of human locomotion, as evident in subjects with brain injuries such as stroke, brain trauma, or people with cerebral palsy, in people with death of dopaminergic neurons in the substantia nigra due to Parkinson’s disease, or in subjects with cerebellar dysfunctions, such as patients with ataxia. The role of cerebellum during locomotion has been shown to be related to coordination and adaptation of movements. Cerebellum is the structure of CNS where are conceivably located the internal models, that are neural representations miming meaningful aspects of our body, such as input/output characteristics of sensorimotor system. Internal model control has been shown to be at the basis of motor strategies for compensating delays or lacks in sensorimotor feedbacks, and some aspects of locomotion need predictive internal control, especially for improving gait dynamic stability, for avoiding obstacles or when sensory feedback is altered or lacking. Furthermore, despite internal model concepts are widespread in neuroscience and neurocognitive science, neurorehabilitation paid far too little attention to the potential role of internal model control on gait recovery. Many important scientists have contributed to this Research Topic with original studies, computational studies, and review articles focused on neural circuits and internal models involved in the control of human locomotion, aiming at understanding the role played in control of locomotion of different neural circuits located at brain, cerebellum, and spinal cord levels.
