Touching a rubber hand: feeling of body ownership is associated with activity in multisensory brain areas (2005, neutral): “A high-resolution, T1-weighted structural image was also collected at the end of the experiment [using a modified driven equilibrium Fourier transform sequence (Ugurbil et al., 1993) with optimized parameters as described by Deichmann et al. (2004)].”
Brain morphometry with multiecho MPRAGE (2008, neutral): “Sophisticated techniques such as point spread function modeling ( Deichmann et al.,2004 )werenot implementedintheoptimization procedure.To avoid potential complications in the analysis related to parallel acceleration, we did not use this feature.”
Regional specificity of MRI contrast parameter changes in normal ageing revealed by voxel-based quantification (VBQ) (2011, methodology): “We achieve whole-brain isotropic voxel size of 1 mm in only 19 min acquisition time, which is comparable with the acquisition time of 13 min for a single T1w high-quality image for VBM (Deichmann et al., 2004).”
Optimal EPI parameters for reduction of susceptibility-induced BOLD sensitivity losses: A whole-brain analysis at 3 T and 1.5 T (2006, methodology): “For anatomical reference and spatial normalization, a high-resolution T 1 -weighted 3D image was acquired for each participant at 1.5 T (3D MDEFT [Deichmann et al., 2004]; FOV = 256 × 224 mm 2 or 256 × 240 mm 2 , matrix size 256 × 224 or 256 × 240, 176 partitions, slab thickness 176 mm, τ 1 = 222.6…”
Quantitative multi-parameter mapping of R1, PD*, MT, and R2* at 3T: a multi-center validation (2013, methodology): “The multi-echo FLASH based T1w imaging, which was compared to MPM here, is less widely used since the advent of MPRAGE and MDEFT based T1w imaging (Mugler and Brookeman, 1990; Deichmann et al., 2000, 2004), since they offer a higher GM/WM contrast-to-noise ratio in the cortex (Tardif et al., 2009).”
The left superior temporal gyrus is a shared substrate for auditory short-term memory and speech comprehension: evidence from 210 patients with stroke (2009, neutral): “56/530 ms (Deichmann et al., 2004).”
London taxi drivers and bus drivers: A structural MRI and neuropsychological analysis (2006, methodology): “Parameters were optimized as described in the literature (Deichmann et al., 2004): for each”
