Procedures and Strategies for Optimizing the Signal-to-Noise Ratio in Event-Related Potential Data
Procedures and Strategies for Optimizing the Signal-to-Noise Ratio in Event-Related Potential Data
This chapter describes how the signal-to-noise ratio of event-related data can be optimized via experimental design considerations, and examines a variety of strategies to optimize the signal-to-noise ratio of event-related potentials, while keeping the length of the experiment down to a reasonable time. It shows that signal quality can be optimized by careful online monitoring of the incoming electoencephalography (EEG) signals during recording, and knowing when and how to fix faulty EEG channels. During offline analysis, several methods are available that can help in removing large recording artifacts from the data.
