Rank-order versus mean based statistics for neuroimaging
收藏 引用
NEUROimage 2007年 第4期35卷 1531-1537页
作者: Rorden, Chris Bonilha, Leonardo Nichols, Thomas E. Univ S Carolina Dept Commun Sci & Disorders Columbia SC 29208 USA Univ S Carolina Dept Neuropsychiat Columbia SC 29208 USA Univ Michigan Dept Biostat Ann Arbor MI 48109 USA
Traditional analysis of neuroimaging data uses parametric statistics, such as the t-test. These tests are designed to detect mean differences. In fact, even nonparametric techniques such as Statistical non-parametric ... 详细信息

A model-based method for retrospective correction of geometric distortions in diffusion-weighted EPI
收藏 引用
NEUROimage 2002年 第1期16卷 177-199页
作者: Andersson, JLR Skare, S Karolinska MR Res Ctr S-17176 Stockholm Sweden
The self-diffusion tensor may be calculated from several echo-planar image acquisitions preceded by different diffusion gradients. Unfortunately, these diffusion gradients cause geometric distortion that must be corre... 详细信息

Voxelwise Bayesian lesion-deficit analysis
收藏 引用
NEUROimage 2008年 第4期40卷 1633-1642页
作者: Chen, Rong Hillis, Argye E. Pawlak, Mikolaj Herskovits, Edward H. Univ Penn Dept Radiol Philadelphia PA 19104 USA Dept Neurol Baltimore MD USA
Relating cognitive deficits to the presence of lesions has been an important means of delineating structure-function associations in the human brain. We propose a voxel-based Bayesian method for lesion-deficit analysi... 详细信息

NEUROimage 2005年 第4期28卷 915-924页
作者: Zhou, J Rajapakse, JC Nanyang Technol Univ Sch Comp Engn Bioinformat Res Ctr Singapore 639798 Singapore
We propose a novel method to automatically segment subcortical structures of human brain in magnetic resonance images by using fuzzy templates. A set of fuzzy templates of the structures based on features such as inte... 详细信息

Parallel networks operating across attentional deployment and motion processing: A multi-seed partial least squares fMRI study
收藏 引用
NEUROimage 2006年 第4期29卷 1192-1202页
作者: Caplan, JB Luks, TL Simpson, GV Glaholt, M McIntosh, AR Baycrest Ctr Geriatr Care Rotman Res Inst Toronto ON M6A 2E1 Canada Univ Calif San Francisco Dynam Neuroimaging Lab San Francisco CA 94143 USA
Anticipatory deployment of attention may operate through networks of brain areas that modulate the representations of to-be-attended items in advance of their occurrence through top-down control. Luks and Simpson (200... 详细信息
