The article discusses the use of event-related brain potentials (ERPs) in studying visual selective attention, highlighting the role of ERP recordings in understanding the timing and localization of stimulus selection processes in the brain. The authors, Steven A. Hillyard and Lourdes Anllo-Vento, from the Department of Neurosciences at the University of California, San Diego, explore how ERPs can provide high-resolution measures of neuronal activity patterns associated with perceptual and cognitive processes. They emphasize the importance of combining ERP data with blood-flow neuroimaging techniques to enhance the understanding of the neural basis of attention. The paper also delves into the mechanisms of spatial attention, the timing of feature selection, and the relationship between spatial and feature selection. The authors conclude that ERPs offer valuable insights into the brain's response to visual stimuli, particularly in the context of attention and selective processing.The article discusses the use of event-related brain potentials (ERPs) in studying visual selective attention, highlighting the role of ERP recordings in understanding the timing and localization of stimulus selection processes in the brain.
