"...In a paper in the journal Neuroimage, O'Connor and her colleagues describe using an fMRI machine to probe the neurological basis for complicated grief among a small sample of women who had lost a close relative to breast cancer. Ordinary grief is apparent on a brain scan: show a bereaved daughter a picture of her mother, and areas of the brain that process emotional pain are activated. The women with complicated grief showed that pattern, but something else as well: activity in the nucleus accumbens, a brain region associated with pleasure, rewards and addiction. "When the women came out of the scanner, the complicated-grief group rated themselves as feeling more negative than the others," O'Connor said.
