    Neuroimage 55:597-606. 2011
    ..At higher acceleration factors, image SNR is reduced and the time-series becomes increasingly thermal noise dominant. However, the tSNR reduction is smaller than the reduction in image SNR due to the presence of physiological noise...

    ..0±6.9 ms and 21.5±1.0 ms for 1.5T and 3T. These experiments showed that at 3T, the BOLD CNR in parenchymal voxels exceeded that of 1.5T by a factor of 1.9±0.4 at the optimal TE for each field...

    Oliver Hinds
    Brain and Cognitive Sciences, Massachusetts Institute of Technology, USA
    Neuroimage 46:915-22. 2009
    ..In addition, that the primary cortical folds predict the location of functional V1 suggests that the mechanism giving rise to V1 location is tied to the development of the cortical folds...

    Oliver Hinds
    Brain and Cognitive Sciences, Massachusetts Institute of Technology, MA, USA

    Neuroimage 55:225-32. 2011
    ..These findings indicate that there are both associations (shared components) and dissociations between the neural systems underlying explicit self-reference and the default mode of brain function...
