P100

What is P100 event-related potential?

The P100 is a positive waveform that peaks at approximately 100 milliseconds after stimulus presentation. The P100’s latency and amplitude vary with aspects of selective attention or stimulus encoding. Latency is considered a measure of stimulus classification speed, and amplitude is proportional to the amount of attentional resources devoted to the task and the degree of information processing required.

What is the evidence for P100 event-related potential?

Moderate to high quality evidence finds a medium-sized reduction in P100 amplitude with neutral and happy face stimuli, but not fearful face stimuli in people with schizophrenia compared to controls.
