Cross-cortical interactions in the human brain remain
poorly understood and are often over-simplified as a 2-dimensional cortical
model in fMRI studies. To date, high-resolution fMRI has been limited to relatively
small brain slabs that cover particular areas of interest, providing fine
mapping of local circuits but precluding macroscale analysis. Here, an EPIK
sequence was used to measure the GE-BOLD signal from individual cortical layers
through most of the brain. The combination of high resolution (0.63 mm isotropic)
and large coverage fMRI enabled identification of long-distance neuronal
interactions that take place between particular cortical depths during
resting-state.
