Electroencephalography (EEG) is practiced by neurologists, cognitive neuroscientists, and others interested in functional brain imaging. Whether for clinical or experimental purposes, all studies share a common purpose-to relate scalp potentials to the underlying neurophysiology. Electrical potentials on the scalp exhibit spatial and temporal patterns that depend on the nature and location of the sources and the way that currents and fields spread through tissue. Because these dynamic patterns are correlated with behavior and cognition, EEG provides a "window on the mind," correlating physiology and psychology. This classic and widely acclaimed text, originally published in 1981, filled the large gap between EEG and the physical sciences. It has now been brought completely up to date and will again serve as an invaluable resource for understanding the principles of electric fields in living tissue and for using hard science to study human consciousness and cognition. No comparable volume exists for it is no easy task to explain the problems of EEG in clear language, with mathematics presented mainly in appendices. Among the many topics covered by the Second Edition are micro and meso (intermediate scale) synaptic sources, electrode placement, choice of reference, volume conduction, power and coherence measures, projection of scalp potentials to dura surface, dynamic signatures of conscious experience, neural networks immersed in global fields of synaptic action, and physiological bases for brain source dynamics. The Second Edition is an invaluable resource for neurologists, neuroscientists (especially cognitive neuroscientists), biomedical engineers, and their students and trainees. It will also appeal to physicists, mathematicians, computer scientists, psychiatrists, and industrial engineers interested in EEG.

David Lewis - Pencil Drawing Techniques

Here is a really good book for the artist who wants to develop his or her pencil drawing abilities, whether it's to improve your preliminary sketch work, or to create beautiful pencil drawings complete in their own right. Pencil Drawing Techniques brings together six of today's best artists, all of whom are incredibly fine instructors as well.

The artists show you how to develop your skill and ability in handling pencil technique. Ferdinand Petrie shows you how to handle pencils and produce a controlled variety of lines, values, and textures. Then he shows you exactly how to use these techniques to draw landscapes in a range of styles and compositions.

Rudy De Reyna explains pencil basics, and explores perspective, size relationships, form, and structure. Douglas grave teaches you how to begin drawing portraits by building a drawing step-by-step. Norman Dams and Joe Singer demonstrate how you can use the pencil to produce spectacular drawings of animals. John Blockley and Richard Bolton show you how pencil drawings can capture the essence of a subject and help you work out a plan for painting it. Finally, Bet Borgeson teaches you all the secrets of colored pencil work and demonstrates a whole new dimension.

The book is divided into seven sections: how to handle a pencil, fundamentals of drawing, drawing landscapes, drawing portraits, drawing animals, drawing for watercolors, and handling color pencils. The copious illustrations show in detail how the artists use their techniques. For the artist who uses the pencil, Pencil Drawing Techniques is an an excellent instructional book of ideas for using the pencil creatively
