Layer-dependent fMRI mapping provides insights to understand the directional information flow within brain networks. However, it is unknown whether larimar fMRI responses allows discrimination of activation to cortical input and/or output. To determine neuronal source of hemodynamic fMRI signals, we investigated the somatosensory-evoked laminar fMRI responses and cortical depth-dependent electrophysiological activities in the mouse cortex.
