Given
the poor specificity and reproducibility of blood oxygenation level
dependent(BOLD), we use cerebral blood flow for the first time to build
resting-state networks of default mode both in patients suffering from
postherpetic neuralgia and healthy subjects, and compare the two groups. The
results of functional connectivity in healthy subjects showed that the areas
activating were the same with the parts previously described in the
literatures using BOLD. The results between-groups comparison showed that
some parts were in strengthened correlation of posterior cingulate cortex in
patients, such as anterior cingulated cortex and insula which are related to
pain.
