Abstract: Provided are a method and apparatus for detecting an event-related potential (ERP), the method including: detecting an R-peak signal by detecting an electrocardiogram (ECG) signal of a subject via an ECG sensor; inducing an evoked potential to the subject by presenting an ERP stimulus to the subject at a certain period on basis of the R-peak signal; and detecting an electroencephalogram (EEG) signal of the subject exposed to the ERP stimulus by using an EEG sensor, and extracting an ERP signal from the EEG signal, wherein intermixture of a heart-rate evoked potential (HEP) of the subject with the ERP signal is inhibited by removing the ERP stimulus being presented to the subject during the certain period, after a latency by a certain time from a point in time the R-peak occurs.
