Brain: Electroencephalography and Imaging

Show Summary Details


The presence of recognizable electrical rhythms of the brain has excited the curiosity and imagination of both professionals and laypeople alike. Psychophysiologists, neurologists, and science fiction writers have been intrigued by the presence of brain activity and the possibility of having an objective noninvasive marker that reflects underlying psychological processes. Some have taken these ideas to the extreme by suggesting that these measures can tell us what someone is thinking or feeling or even if they are telling the truth. Although it is not that simple, some researchers have begun to use brain activity to help physically disabled individuals to communicate, to move paralyzed limbs, or even to reduce seizure disorders. Understanding cortical processes through various forms of brain imaging is a complex task. Scientists have come to appreciate the complicated relationship that exists between electrocortical measures and cognitive, emotional, and behavioral processes. This chapter discusses spontaneous electroencephalography, event-related potentials, electrodes and electrode placement, and brain imaging techniques such as magnetoencephalography, positron emission tomography, and magnetic resonance imaging.
