Increasing the effect size in event-related fMRI studies.

Increasing the effect size in event-related fMRI studies.

Independent component analysis (ICA) has proved to be a powerful method for exploratory analysis of functional magnetic resonance imaging (fMRI) data. It has been used to uncover unexpected activations in fMRI data derived from brain activation. ICA has been used to characterize other sources of var...
