Functional Connectivity Architecture of the Human Brain

Danhong Wang, Hesheng Liu
2014 The Neuroscientist  
We propose that a series of changes in connectivity architecture occurred in response to the pressure for processing efficiency in the enlarged brain.  ...  We then offer a hypothesis about how the cortical surface expansion during human evolution may have led to remarkable intersubject variability in brain connectivity.  ...  For example, the mixture of variability can significantly confound the findings when studying individual differences in the language network.  ...

2006 Cerebral Cortex  
Additional leftward asymmetries connecting the parietal and frontal lobes to the temporal lobe may be more closely related to laterality of language.  ...  We applied an MRI technique known as diffusion tensor tractography to reveal the morphology of the white matter in vivo by mapping directions of maximum water diffusion in brain tissue.  ...  Additional significant leftward asymmetries connecting the parietal and frontal lobes to the temporal lobe may be more closely related to laterality of language.  ...

Neuroimaging of Language: Why Hasn't a Clearer Picture Emerged?

Evelina Fedorenko, Nancy Kanwisher
2009 Language and Linguistics Compass  
(ii) Are regions engaged in language processing specific to the domain of language? Neuroimaging has not yet provided clear answers to either question.  ...  We argue that this approach can obscure functional specificity because of the anatomical variability across individual brains, and we advocate the use of an alternative approach -the functional localization  ...  We would also like to thank Bettiann McKay for editorial assistance.  ...

What Are the Synergies between Paleoanthropology and Brain Imaging?

Antoine Balzeau, Jean-François Mangin
2021 Symmetry  
Models of intra- and inter-species variability in brain morphology inferred from large neuroimaging databases will help make the most of the rare endocasts of extinct species.  ...  Improving our understanding of the morphology of the endocast necessarily involves studying the external surface of the brain and the link it maintains with the internal surface of the skull.  ...  Acknowledgments: The authors thank the MNHN for the data for Cro Magnon 1 and La Chapelleaux-Saints; the 3D mapping of the asymmetries was calculated by S. Prima for a shared study.  ...

2002 NeuroImage  
We extend these studies to whole brain imaging at 1.5 T, properly accounting for intersubject variation using random effects analysis.  ...  In addition, session-dependent changes in activation were greater in some regions than others and may indicate areas of brain, such as the supplementary eye fields, that are sensitive to attentional modulation  ...  Scatter plots of intersubject variability are shown for additional ROIs in Fig. 4 . The ROIs containing occipital cortex and frontal eye fields had the least subject-to-subject variation.  ...
