Using sub-millimeter BOLD and blood-volume-sensitive (VASO) fMRI in the human motor cortex, we demonstrated that the motor preparatory inhibition can be observed in the primary motor cortex in a layer dependent manner.
Figure 1 (A) BOLD signal activity maps from a representative participant and MRI data acquisition parameters. (B) Averaged (n = 5) response times for three task conditions. (C) Upper panel; Cortical profiles of VASO and BOLD activity changes in the hand-knob area. Lower panel; Activity changes averaged within superficial and deep layers. Error bars indicate the standard error of means across participants. M, Movement; PM, Prepared Movement.
