On having one's data shared is a comment to the Dan Lloyd's paper, Functional MRI and the study of human consciousness, that reanalyzed the data set from Bradley R. Postle and co-workers Activity in human frontal cortex associated with spatial working memory and saccadic behavior.
Bradley R. Postle and co-authors critize several aspect with the Dan Lloyd paper:
- The change in distance between between temporal ordered brain scans may be observed under trivial circumstances.
- During scanning one of the fluctuation may be non-conscioussness-related changes such as habituation
- The BOLD fMRI has drift (low frequency noise).
Apart from the critique of the Dan Lloyd paper they also have concerns about the time and resources for submission to the fMRI Data Center.
Later Bradley Postle would publish another critical comment for another reanalysis of his data: Analysis of fMRI data from tasks containing temporal dependencies: an evaluation of Slotnick (2005)
