WHEN IS IT SENSIBLE TO USE PET TO STUDY BRAIN-FUNCTION

Posner & Raichle's book is a superbly presented and well-written overv iew of a fast-developing and important field in contemporary neuroscie nce. It suffers from being an overview, however, because it does not g o into sufficient detail or depth in many of the issues that it raises . It also neglects many other important areas of current research, for example, technical advances in other areas, learning and memory, and lesion analysis of brain function.
