“…One of the major concerns is about the different approaches used for the preprocessing and analysis of data, which can give rise to different results (Ashburner & Friston, 2011) and thus could contribute toward explaining the inconsistencies in the field of bilingualism. Tables 1-2 summarize the preprocessing and analysis of the studies included in this review.…”

Abstract:The neuroanatomical bases of bilingualism have recently received intensive attention.However, it is still a matter of debate how the brain structure changes due to bilingual experience since current findings are highly variable. The aim of this review is to examine these structural studies from a methodological perspective and to discuss two major methodological problems that could give rise to this variability. The first problem is sample selection, an issue directly related to the heterogeneous nature of bilingualism. The second problem is the inconsistency in the methods used for the analysis of brain imaging data. This review reveals that although structural changes related to bilingualism have been reported in regions comprising language/cognitive control and language processing, these results are not yet sufficiently numerous or consistent to allow important generalizations to be reached. Consequently, current evidence offers ambiguous support for neural models of bilingualism. This shortcoming in the field is exacerbated by critical methodological differences between studies that only further complicate the matter. We conclude by identifying issues that should be taken into consideration so that studies are more comparable and results are easier to aggregate and interpret. We also point out future directions that would allow for progress in the field.

“…The baseline GM, WM and CSF segmentations were then used to generate a group average template using the diffeomorphic warping ‘ Shoot ’ algorithm in SPM12 21. The segmentations were then warped using the resulting deformation fields, modulated with the Jacobian determinant data and smoothed with a 6 mm full-width half-maximum (FWHM) Gaussian kernel.…”

“…The study‐specific template is then normalized to MNI space in step 1(c). Two deformations, the flow field images representing individual image to study‐specific template and the transformations of the template to MNI space, were combined and encoded in modulated images.SHOOT ST is the same as option 2 except that the two implementations of DARTEL were replaced by a diffeomorphic registration using geodesic shooting and Gauss‐Newton optimization22 (Supp. Fig.…”

PurposeTo examine progressive brain changes associated with chronic fatigue syndrome (CFS).Materials and MethodsWe investigated progressive brain changes with longitudinal MRI in 15 CFS and 10 normal controls (NCs) scanned twice 6 years apart on the same 1.5 Tesla (T) scanner. MR images yielded gray matter (GM) volumes, white matter (WM) volumes, and T1‐ and T2‐weighted signal intensities (T1w and T2w). Each participant was characterized with Bell disability scores, and somatic and neurological symptom scores. We tested for differences in longitudinal changes between CFS and NC groups, inter group differences between pooled CFS and pooled NC populations, and correlations between MRI and symptom scores using voxel based morphometry. The analysis methodologies were first optimized using simulated atrophy.ResultsWe found a significant decrease in WM volumes in the left inferior fronto‐occipital fasciculus (IFOF) in CFS while in NCs it was unchanged (family wise error adjusted cluster level P value, P FWE < 0.05). This longitudinal finding was consolidated by the group comparisons which detected significantly decreased regional WM volumes in adjacent regions (P FWE < 0.05) and decreased GM and blood volumes in contralateral regions (P FWE < 0.05). Moreover, the regional GM and WM volumes and T2w in those areas showed significant correlations with CFS symptom scores (P FWE < 0.05).ConclusionThe results suggested that CFS is associated with IFOF WM deficits which continue to deteriorate at an abnormal rate.
