Ultra-high field fMRI allows us to detect the functional sensory pathway including thalamic nuclei. Although hemodynamic response function is determined spatially by the vascular architecture and temporally by the evolution of hemodynamic changes, fMRI signals may provide insight into tracking sequential neural processing. Here, we investigated the spatiotemporal evolution of functional sensory pathways during forepaw stimulation in anesthetized mice using ultra-high field BOLD fMRI.
