Comparison of DOMS-related activation by contraction and physical stimulation in the cerebellum.

<p>Multi studies of activation following both means of stimulation in a standardized Talairach brain. Clusters were calculated by GLM contrasts between painful and non-painful stimulation conditions (t≥5). Dark green: activation by painful contraction; light green: activation by painful physical stimulation; orange: common activation by both painful stimuli. <b>a, b, d.</b> coronal and sagittal section showing orientation of transverse sections in c. <b>c.</b> In the cerebellum, contraction activates widespread areas. <b>d, e.</b> timeline of the BOLD-signal (average over 5 stimulus periods) for painful contraction (d) and painful stimulation (e) in the same cluster of the anterior cerebellum (circled cluster in c) shown as red timelines. Painless contraction/ painless physical stimulation shown as blue timeline.
