Since becoming commercially available in 1985, transcranial magnetic stimulation (TMS) has emerged as an important tool in several areas of neuroscience. Originally envisioned as a way to measure the responsiveness and conduction speed of neurons and synapses in the brain and spinal cord, TMS has also become an important tool for changing the activity of brain neurons and the functions they subserve and an important adjunct to brain imaging and mapping techniques. Along with transcranial electrical stimulation techniques, TMS has diffused far beyond the borders of clinical neurophysiology and into cognitive, perceptual, behavioural, and therapeutic investigation and attracted a highly diverse group of users and would-be users.This book provides an authoritative review of the scientific and technical background required to understand transcranial stimulation techniques and a wide-ranging survey of their burgeoning application in neurophysiology, perception, cognition, emotion, and clinical practice. Each of its six sections deals with a major area and is edited by an international authority therein. It will serve researchers, clinicians, students, and others as the definitive text in this area for years to come.

Perceptual Constancy examines a group of long-standing problems in the field of perception and provides a review of the fundamentals of the problems and their solutions. Experts in several different fields - including computational vision, physiology, neuropsychology, psychophysics and comparative psychology - present their approaches to one of the fundamental problems of perception: how does the brain extract a stable world from an ever-changing retinal input? How do we achieve color constancy despite changes in the wavelength content of daylight? How do we recognize objects from different viewpoints? And how do we know the sizes of those objects? The volume is divided into three sections, each of which addresses developmental, clinical and comparative issues, psychophysics, and physiology.

This book presents a collection of analog electronic circuits based on the op-amp, supported by a wealth of practical detail which will enable the reader to speedily select, build and test a desired circuit. The book is primarily intended to be a practical reference volume rather than a teaching text. Readers will discover an extensive and invaluable source of functional and established analog circuits, from integrators and differentiators to logarithmic amplifiers, from filters to instrumentation amplifiers. The circuits are grouped according to function, and the approach is to build up slowly from the basic textbook examples towards a series of practical, workable circuits. Students who need to build and test particular types of analog circuitry as part of an assignment or project based activities will find this book invaluable. Professional engineers will also find the book useful for design and development work. The coverage is extensive and up-to-date, and provides a wealth of technical advice.
