I don't have a long commentary to write about Multi-voxel coding of stimuli, rules, and responses in human frontoparietal cortex except to say that reading the methods (and the rest of the paper) was very pleasant: the software, algorithms, preprocessing, etc. are all clearly and thoroughly described, without becoming bogged down. Next time I'm asked for an example of how to write up an MVPA study, this is the paper I'll recommend.
