Reference request for creator of heuristic for processing fMRI data (T.Nichols)
I know very little about fmri, but as @strongbad points out, surely it is Professor Thomas Nichols at Warwick.

I'm not sure what the authoritative reference is, but Luo and Nichols (2003) might be worth a look. They state:


  We construct a histogram based on all non-tail data (10th to 90th percentile) and use the location of the minimum bin as the antimode estimate.
