Electroencephalography (EEG) measures the brain's electrical activity through electrodes placed on the scalp, while Event-Related Potentials (ERPs) are specific changes in EEG activity that are time-locked to sensory, motor, or cognitive events. This combination allows for the investigation of rapid neural processes underlying perception, cognition, and motor control. A key feature is its excellent temporal resolution, enabling researchers to pinpoint the precise timing of brain responses to specific stimuli and offering valuable insights into the neurophysiological correlates of mental processes, often used in cognitive neuroscience and clinical diagnostics.
