P300

The P300 is a specific brainwave pattern that occurs approximately 300 milliseconds after a person recognizes something meaningful or unexpected. It is often detected using an EEG (electroencephalogram) and reflects the brain's process of paying attention, updating information, or recognizing important stimuli. In practical terms, the P300 indicates that your brain has detected and responded to relevant or surprising information, helping researchers understand how the brain processes attention and decision-making. It’s useful in fields like neuroscience, psychology, and medical diagnostics to assess cognitive function.
