Stimulus-Independent Data Analysis for fMRI

Silke Dodel, J. Michael Herrmann, Theo Geisel

Research output: Chapter in Book/Report/Conference proceedingChapter


We discuss methods for analyzing fMRI data, stimulus-based such as baseline substraction and correlation analysis versus stimulus- independent methods such as Principal Component Analysis (PCA) and Independent Component Analysis (ICA) with respect to their capabil- ities of separating noise sources from functional activity. The methods are applied to a finger tapping fMRI experiment and it is shown that the stimulus-independent methods in addition to the extraction of the stimulus can reveal several non-stimulus related influences such as head movements or breathing.
