18 genetic variants have been identified which appear to be associated with alcohol use disorder and heavy drinking. Of these genes, five were overlapped, eight were associated with heavy consumption and five were linked to an increased risk of AUD. The study concluded that while heavy drinking is a risk factor for alcoholism, it is not a sufficient cause of the disorder.
A new study reveals that most of the specific genes long thought to be linked to intelligence probably have no bearing on one’s IQ. And it may be some time before researchers can identify intelligence’s specific genetic roots.
The effect music has on people may be genetically determined by dopamine functionality, a new study reports.
Researchers report a disruption in a brain circuit could contribute to the auditory hallucinations associated with schizophrenia.
People with a variation of the DRD2 gene are more resilient to the effects of sleep deprivation when completing tasks that require cognitive flexibility, a new study reports.
Researchers report on a link between the dopamine system and initiating joint attention in children at high risk for autism.
Researchers identified genetic variants that can predispose children to dyslexia and language impairment. The study could allow for earlier diagnosis and more successful interventions for language impairment disorders.
Dopamine D2 receptor overexpression in cholinergic interneurons of the nucleus accumbens may explain why some are more prone to cocaine addiction than others.
Researchers have identified two groups of serotonin neurons that may help to suppress aggression in mice.
Dietary triglycerides directly alter signaling in the reward circuit to regulate behavior. The findings reveal a potential mechanism by which triglyceride-rich diets may lead to adaptions in dopamine signaling that underlie reward deficit and compulsive behaviors.
