How to Lie with fMRI Statistics

How to Lie with fMRI Statistics:
fMRI Statistics provide another means by which "lie" to produce misleading data, often unintentionally, and it's essential that readers be aware of some of the pitfalls both when producing and consuming neuroimaging data. This is also not intended as fodder for the anti-fMRI crowd who argue that it's all bunk-- fMRI results can be very robust and reliable but its important that both the producers and consumers know how to determine what's real. For good data, it often doesn't matter what stats are done -- the effect will be obvious.

They are intended to provide (1) an introduction to functional magnetic resonance imaging (fMRI), with an emphasis on design and analysis, for students who are new to the field and (2) a reference for experienced users (particularly the brain anatomy sections), and (3) information for collaborators visiting Robarts Research Institute to assist them in planning well-designed and practical experiments on our system.

SPM2

SPM2

SPM2 - released 12th May 2003
SPM2 is a major update to the SPM software, containing substantial theoretical, algorithmic, structural and interface enhancements over previous versions

CAMBRIDGE IMAGERS - SPM2 analysis defaults

This page describes some analysis defaults for SPM2. The FMRI defaults page describes how to get the data and process it ready for SPM analysis. This page describes the specifics of SPM2 analysis. It starts after you have done all the processing described on the FMRI defaults page, up to the end of the slice-timing step (the slice timing is the same in SPM99 and SPM2).

Brain unfolding and flattening to view multiple visual areas

We have developed algorithms for stripping off the skull and then reconstructing the complete folded cortical surface of each cerebral hemisphere from structural MRI images. Once we have obtained a surface free of topological defects, it can be unfolded to better view the location of visual areas which in real life are partly hidden in deep fissures (sulci). This procedure works by gradually reducing curvature while trying to minimize areal and angular distortion. "
