"The standardized power of periodic signal change at the frequency of alternation between the control and activation conditions was estimated by fitting a sinusoidal regression model, by means of an iterated least squares procedure, to the movement-corrected time functional MRI series at each voxel."
This one's a little better:
"This map was thresholded to generate a set of spatially contiguous three-dimensional clusters of suprathreshold voxel statistics, and the sum of suprathreshold voxel statistics in each cluster was tested against its sampled permutation distribution under the null hypothesis of zero group effect with a twotailed p value of <0.01>."
If anyone has any clue what the heck that means (or what the author was smoking when she wrote it), please let me know, because I most certainly don't. Until then, I'll be hanging out at the library, sweating buckets to get through a mere three page essay and hopefully walk away with some (I'll even take any) level of comprehension whatsoever.
