Despite a fundamental interest in the relationship between structure and function, the relationships between measures of white matter microstructural coherence and functional brain responses to pain are poorly understood. We investigate whether fractional anisotropy (FA) in two white matter regions in pathways associated with pain is related to the fMRI Blood oxygen level dependent (BOLD) response to thermal stimulation. BOLD fMRI was measured from 16 healthy male subjects during painful thermal stimulation of the right arm.
