Abstract
Norman et al. [ 1 Norman K.A. et al. Beyond mind-reading: multi-voxel pattern analysis of fMRI data. Trends Cogn. Sci. 2006; 10: 424-430 Abstract Full Text Full Text PDF PubMed Scopus (1613) Google Scholar ] recently reviewed the use of multi-voxel pattern analysis (MVPA) of fMRI data. They provided examples that showed that patterns of activation across a set of voxels can contain far more information about mental states than the more typically used univariate approach. Patterns of fMRI activation can be used to discriminate cognitive states (sometimes called ‘mind reading’), to relate brain activity to behaviour and to clarify the structure of neural representations. Here, we point out an additional use of MVPA: its ability to interpret overlapping functional activations.
