Independent components (ICA) of ERPs

How Can We Help?

These independent components of ERP linearly mixed will comprise the original averaged ERP signal. Each component is an independent piece of the ERP signal, representing a stage in the processing of the perception and then the motor aspects and then the cingulate’s self monitoring of the response. Though inter-related, each piece is a separate stage in the sequential process that creates the complexity of the ERP itself.

In WInEEG software we apply Infomax ICA algorithm to decompose original ERP into Independent Components and get these graphical ERP components you see in the display as well separately to de-artifact the original EEG data before processing.
