The connection between dopamine and counterfactual information, or notions of relief and regret, is altered in those with alcohol use disorder.
Levodopa, a drug commonly prescribed for the treatment of Parkinson's disease that increases dopamine in the brain was found to reverse the effects of neuroinflammation on the reward system and improve symptoms associated with depression.
A new test that measures dopamine levels in biological fluids could help with the detection of depression, Parkinson's disease, and other disordered marked by abnormal dopamine levels.
Researchers have identified how two different populations of neurons in the striatum are affected differently in Huntington's disease. The neurodegeneration of one of these populations leads to motor defects while damage to the other population located in striosomes may account for mood disorders associated with the early stages of Huntington's.
Diphenylbutylpiperidines (DPBPs), an older class of antipsychotic medications can effectively be repurposed to help treat type 2 diabetes, a new study reports.
Researchers have developed a soft, implantable brain probe that can monitor serotonin and dopamine activity in real-time.
Study reveals how methylphenidate interacts with cognitive control networks and attention behaviors. Methylphenidate changes spontaneous neural activity in reward and cognitive control systems in children with ADHD. The changes result in more stable sustained attention.
Krill oil protects dopaminergic neurons from age-related degeneration, decreases alpha-synuclein aggregation, and improves dopamine-dependent cognition and behavior in lab models of Parkinson's disease.
Study reveals the mechanism of the nucleus accumbens for mediating reward and aversion.
Researchers shed light on how different SSRI antidepressants may work to help fight symptoms of depression in the brain.
Exercise can help improve mood and overall symptoms of those who suffer from seasonal affective disorder (SAD).
The dopamine system helps the brain anticipate the occurrence and duration of unpleasant events, but without taking errors into account.
