Multi-echo fMRI of the cortical laminae in humans at 7Â T

► High-resolution (0.75 mm) fMRI of cortical laminae at 7 T using multi-echo. ► Large, convoluted brain areas can be analysed using FreeSurfer's surface reconstruction. ► Laminar T2⁎ profiles correlate well with cortical myelin density. ► Laminar temporal noise profiles correlate well with cortical blood density. ► Optimal TE is layer-dependent and T2⁎ of 'active' venous blood is not negligible.
