Research findings show decreased benzodiazepine receptor binding in the left temporal pole among patients with GAD, indicating a potential link between brain structure and anxiety. The study's results suggest that high regional heterogeneity may be necessary for adaptation to living organisms.
The study uses genotypic selection to identify a quantitative trait locus (QTL) associated with alcohol consumption in mice. The results provide experimental confirmation of the QTL and suggest that this method can be used to determine genetic susceptibility to alcoholism.
Researchers have found a possible genetic cause of bipolar affective disorder, linking it to the serotonin transporter gene. The study suggests that variations in this gene may lead to unstable moods and increased susceptibility to the illness.
