Abstract

The lateralized readiness potential (LRP) is a component of average event-related potentials that has proven very useful in the study of hand-specific motor preparation. We developed a model of single-trial LRP waveforms that produces realistic average waveforms for both stimulus-locked and response-locked averaging. This model may be useful in computer simulation studies of LRP scoring methods, and it may open up the possibility of ultimately retrieving trial-by-trial information about LRP activity.
