The ultra-high magnetic field strengths of 14.1T allows visualization of laminar-specific neurovascular coupling events with fMRI in living animals. Combining line-scanning fMRI and intracellular calcium signal recording, we present laminar-specific coupling features at high temporal and spatial resolution along the cortical thickness, showing strong Layer 4 fMRI correlation to the calcium signal and largely varied coupling features from adjacent cortices in the anesthetized rats.
