A key moment in this new understanding came in 1997, when a research team from Washington University published a pair of papers in the prestigious Journal of Cognitive Neuroscience. During this period, PET scanners, which were originally developed for medical purposes, were migrating into neuroscience research, where they provided researchers the breakthrough ability to observe brain activity. The Washington University team looked at a collection of these new brain imaging studies to investigate a simple question: Are there regions of the brain that are involved in all types of brain activity? As the psychologist Matthew Liebe...
