Event-Related Potential
This essay stresses that the ongoing electroencephalogram (EEG) provides a satisfactory scale for accessing temporal evolution of the brain activity associated with cognitive processes in health and disease. However, momentary changes in brain activity, as reflected in EEG, are rarely exploited due to lack of analytical tools and methodology. The electrodes covering the parietal lobe typically measure the P300 signal most strongly. The presence, magnitude, topography and time of this signal are often used as metrics of cognitive function in decision-making processes. While the neural...
