He added, "One of the key sites for love-induced analgesia is the nucleus accumbens, a key reward addiction centre for opioids, cocaine and other drugs of abuse.

The relationship between reward processing and pain relief is supported by prior research showing analgesic benefits from pharmacologic manipulation of key reward systems [11], [13], [14].

For example, the nucleus accumbens and ventral tegmental area (two key reward processing structures) both play an important role in analgesic processes [11] [14] – perhaps explaining why pleasurable and appetitive states such as sucrose consumption and anticipation of food reward reduce pain [15].

ATF4 expression in the nucleus accumbens (NA), a key reward region in the brain, is induced by amphetamine administration or restraint stress, and ATF4 overexpression in this region decreases the behavioural responsiveness to amphetamine (12).

A chronic ghrelin/saline infusion protocol was used in preference to acute injection in order to increase chances of seeing an effect on gene expression; moreover, if ghrelin is an important regulator of the reward system in the long term, promoting overeating and obesity, its chronic effects to alter key reward mechanisms are likely to be of considerable importance.
