ERP waveforms

ERP (Event-Related Potential) waveforms are brain signals recorded via EEG that reflect the brain's electrical response to specific events or stimuli, like seeing a picture or hearing a sound. These waveforms show characteristic patterns, such as peaks and valleys, occurring milliseconds after the event, which help researchers understand how the brain processes information. Think of ERPs as the brain's electrical "footprints" disturbed by particular stimuli, allowing scientists to study cognitive functions like attention, perception, and memory in real-time.
