Download or read book Mirror Neuron Systems written by Jaime A. Pineda and published by Springer Science & Business Media. This book was released on 2009-03-01 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to bring together social scientists, cognitive scientists, psychologists, neuroscientists, neuropsychologists and others to promote a dialogue about the variety of processes involved in social cognition, as well as the relevance of mirroring neural systems to those processes. Social cognition is a broad discipline that encompasses many issues not yet adequately addressed by neurobiologists. Yet, it is a strong belief that framing these issues in terms of the neural basis of social cognition, especially within an evolutionary perspective, can be a very fruitful strategy. This book includes some of the leading thinkers in the nascent field of mirroring processes and reflects the authors’ attempts to till common ground from a variety of perspectives. The book raises contrary views and addresses some of the most vexing yet core questions in the field – providing the basis for extended discussion among interested readers and laying down guidelines for future research. It has been argued that interaction with members of one’s own social group enhances cognitive development in primates and especially humans (Barrett & Henzi, 2005). Byrne and Whiten (1988), Donald (1991), and others have speculated that abilities such as cooperation, deception, and imitation led to increasingly complex social interactions among primates resulting in a tremendous expansion of the cerebral cortex. The evolutionary significance of an imitation capability in primates is matched by its ontological consequences.

Download or read book Development of a Microwave Modulated Dual Optical Wavelength Geodetic Distance measuring Instrument written by J. C. Owens and published by . This book was released on 1968 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accuracy of optical distance measurements on horizontal paths is limited at present to several parts per million by uncertainty in knowledge of the average air density along the path. This report describes the development and testing of a prototype instrument capable of significant;y greater accuracy, probably as high as 0.1 ppm. The instrument makes simultaneous measurements of transit time using two superimposed beams of light which have different optical wavelengths but which are modulated at a common microwave frequency. From the difference in transit times for the two colors, plus the absolute transit for either one, the average refractive index along the path and hence the true geodetic path length can be determined. Tests over a 5.3 -km patch have given a standard error of 0.3 ppm in corrected distance, and it is believed that even better results can be obtained. The system is described in detail, including modifications that would significantly increase its accuracy and range.

Download or read book Optical Systems for Soft X Rays written by A.G. Michette and published by Springer. This book was released on 1884 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental problem in cell biology is the cause of aging. The solution to this problem has not yet been obtained because,(l) until recently, it was not possible to image living cells directly. The use of low-energy (soft) X rays has made such imaging possible, perhaps thereby allowing the aging process to be understood and possibly overcome (a result that may well generate further social, moral, and ethical problems). Fortun ately this is not the only aspect of cell biology amenable to soft X-ray imaging, and it is envisaged that many less controversial studies--such as investigations of the detailed differences between healthy and diseased or malignant cells (in their natural states) and processes of cell division and growth-will be made possible. The use of soft X rays is not limited to biological studies-many applications are possible in, for example, fusion research, materials science, and astronomy. Such studies have only recently begun in earnest because several difficulties had to be overcome, major among these being the lack (for some purposes) of sufficiently intense sources, and the technological difficulties associated with making efficient optical systems. As is well known, the advent of dedicated synchrotron radiation sources, in particular, has alleviated the first of these difficulties, not just for the soft X-ray region. It is the purpose of this book to consider progress in the second.

Download or read book Advanced Free Space Optics FSO written by Arun K. Majumdar and published by Springer. This book was released on 2014-09-10 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title provides a comprehensive, unified tutorial covering the most recent advances in the emerging technology of free-space optics (FSO), a field in which interest and attention continue to grow along with the number of new challenges. This book is intended as an all-inclusive source to serve the needs of those who require information about the fundamentals of FSO, as well as up-to-date advanced knowledge of the state-of-the-art in the technologies available today. This text is intended for graduate students, and will also be useful for research scientists and engineers with an interest in the field. FSO communication is a practical solution for creating a three dimensional global broadband communications grid, offering bandwidths far beyond what is possible in the Radio Frequency (RF) range. However, the attributes of atmospheric turbulence and scattering impose perennial limitations on availability and reliability of FSO links. From a systems point-of-view, this groundbreaking book provides a thorough understanding of channel behavior, which can be used to design and evaluate optimum transmission techniques that operate under realistic atmospheric conditions. Topics addressed include: • FSO Physical and Statistical Models: Single/Multiple Inputs/Outputs • Understanding FSO: Theory and Systems Analysis • Modulation and Coding for Free-Space Optical Channels • Atmospheric Mitigation and Compensation for FSO Links • Non-line-of-sight (NLOS) Ultraviolet and Indoor FSO Communications • FSO Platforms: UAV and Mobile • Retromodulators for Free Space Data links • Hybrid Optical RF Communications • Free-space and Atmospheric Quantum Communications • Other related topics: Chaos-based and Terahertz (THz) FSO Communications

Download or read book Learned Brain Self Regulation for Emotional Processing and Attentional Modulation From Theory to Clinical Applications written by Sergio Ruiz and published by Frontiers Media SA. This book was released on 2016-10-19 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mounting evidence in the last years has demonstrated that self-regulation of brain activity can successfully be achieved by neurofeedback (NF). These methodologies have constituted themselves as new tools for cognitive neuroscience establishing causal links between voluntary brain activations and cognition and behavior, and as potential novel approaches for clinical applications in severe neuropsychiatric disorders (e.g. schizophrenia, depression, Parkinson´s disease, etc.). Current developments of brain imaging-based neurofeedback include the study of the behavioral modifications and neural reorganization produced by learned regulation of the activity of circumscribed brain regions and neuronal network activations. In a rapidly developing field, many open questions and controversies have arisen, i.e. choosing the proper experimental design, the adequate use of control conditions and subjects, the mechanism of learning involved in brain self-regulation, and the still unexplored potential long-lasting effect on brain reorganization and clinical alleviation, among others. This special issue on self-regulation of the brain of emotion and attention using NF approaches interested authors to report technical and methodological advances, scientific investigations in understanding the relation between brain activity and behaviour using NF, and finally studies developing clinical treatment of emotional and attentional disorders. The editors of this special issue anticipate rapid developments in this emerging field.
