Abstract: Human functional neuroimaging with high-field MRI is difficult. One of the mostimportant challenges is due to spatial inhomogeneities in the static magnetic field B0,which leads to both local geometric distortions and local functional signal loss. Amore general problem in fMRI is related to the calibration of the neurovascular BOLDsignal to estimate activation that is more specific to neuronal sources. Many methods existto address these issues, but normally they do not come as ready-to-use scanner-specificpackages with the MRI system. The talk will summarize experiences in optimizingfunctional sensitivity in temporal and frontal areas, optimization of functionalspecificity by CMRO2 estimation and applications for the study of resting statenetworks.
