N250
What is N250 event related potential?
The N250 wave is an event-related brain potential (ERP) measured using electroencephalography (EEG). The N250 is a negative waveform that peaks at approximately 250 msec after stimulus presentation. It is observed at fronto-central sites in response to face stimuli, and so it may reflect a neural mechanism for detection of human faces.
What is the evidence for N250 event related potential?
High quality evidence shows people with schizophrenia have a medium-sized reduction in N250 amplitude compared to controls during exposure to face stimuli.
