A study of norepinephrine levels in gamblers found high cerebrospinal fluid (CSF) levels of the norepinephrine (NE) metabolite 3-methoq-4-hydroxyphenylglycol (MI-IPG). This could suggest a relationship between the noradrenergic system and gambling, and gambling could be seen as a reward-dependent behavior, but according to Cloninger’s theory these gamblers should exhibit low levels of NE, not high. Cloninger suggests that had these gamblers been retested after they had refrained from gambling for a determined period, their CSF MHPG levels might have been low. A study of norepinephrine levels in alcoholics with high reward dependence also showed a significant decrease of MHPG in their CSF. This finding demonstrates a significant relationship between reward dependence and norepinephrine.
Several genes have also been found to express the RD temperament dimension. Specifically, the gene MAOA-uVNTR has been highly implicated in evoking the RD personality trait.

Famous quotes containing the word research:
“The working woman may be quick to see any problems with children as her fault because she isnt as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesnt have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
“After all, the ultimate goal of all research is not objectivity, but truth.”
