P1-N1-P2

event related potential

This is a graph of a few late components of an event-related potential. The red line shows the passive condition, the black line shows the active condition.1

In the human ERP, the P50 (P1), N100 (N1), P200 (P2), N200 (N2), and P300 (P3) components can be distinguished.2

P1m-N1m-P2m is the magnetic equivalent of P1-N1-P2.3
M50 is the magnetic equivalent of P50.4  
M100 is the magnetic equivalent of N100.5
