Abstract:

Objective To explore the role of marginal division of the human brain in the pain modulation.Methods Resting functional magnetic resonance imaging was applied in a patient with right extremities pain caused by a malacia lesion in the left putamen and in 8 healthy volunteers.Marginal division was defined using manual drawing on structure images,and was applied to the computation of fuctional connectivity maps.Results The functional connectivities in the left marginal division showed an evident decrease in the patient when compared with healthy controls.These connectivities were mainly located in the bilateral head of caudate nucleus,putamen,and left globus pallidus.Conclusion The marginal division may be involved in the pain modulation.

Key words: marginal division, putamen, brain, functional magnetic resonance imaging, functional connectivity
