Axial (cross sectional) fMRI of the brain during bilateral finger-tapping. Areas of BOLD (blood oxygen level dependent) activation have been overlaid on a structural 3D volume T1 weighted sequence. Normally expected brain activation is seen bilaterally in the hand motor knob regions of the pre-central gyri (precg) (primary motor area), which straddles the central sulcus extending into the post-central gyri (pocg). BOLD activation in both supplementary motor regions (SMA) is seen. | |
