[Daniel Tammet is definitely the subject of this study, named “DT” in this paper. The fMRI study failed to find expected activity that would indicate synaesthesia, but did find activity consistent with the use of the memory technique known as “chunking”. Authors tried to explain findings with a claim that Tammet’s synaesthesia is a special type.]
