• Laminar analysis of 7 T BOLD using an imposed spatial activation pattern in human V1 (2010, methodology): “Because the curvature in V1 is predominantly negative there were consistently fewer voxels (on average 1% across subjects within V1) intersecting the white matter surface than the pial surface, and this albeit small difference was significant in our population (pb0.”
• Imaging retinotopic maps in the human brain (2010, unknown): “There have been several reports that ocular dominance columns can be identified using fMRI (Adams & Horton, 2009; Cheng et al., 2001; Goodyear et al., 2002; Menon et al., 1997; Yacoub et al., 2007), but the method has not yet”
• Cultural recycling of cortical maps. (2007, unknown): “Finally, even if human cortex contains columnar structures, it is unclear whether human neuroimaging will ever gain direct access to this representational level, beyond the simplest case of ocular dominance columns (Yacoub et al., 2007).”
• Pushing spatial and temporal resolution for functional and diffusion MRI in the Human Connectome Project (2013, background): “…specific activation at very highmagnetic fields, either when the large vessel effects are suppressed, as in spin-echo fMRI (Olman et al., 2012; Yacoub et al., 2007, 2008; Zimmermann et al., 2011), or even in their continued presence (Cheng et al., 2001; Koopmans et al., 2010; Menon et al.,…”
• High-field fMRI unveils orientation columns in humans (2008, methodology): “In the human ODC work (21), we demonstrated that BOLD (blood oxygen level-dependent) contrast sampled not with conventional gradient echo (GE) but probed through spin echoes (SE) at ultrahigh magnetic fields (7 T), yielded accurate and reproducible (over days) ODC maps that were unaffected by nonspe”
