Fluctuations in the dopaminergic midbrain play a critical role in risky decision making.
Mice infected with bacteria that cause mild intestinal infections exhibited Parkinson's like symptoms later in life. The findings provide a pathophysiological model in which intestinal infections may act as a trigger for Parkinson's disease.
A new study reports neuromelanin sensitive MRI is able to measure dopamine function associated with psychosis.
A new study reports the combination of a toxic herbicide and lectins may trigger Parkinsonism after the toxins travel from the stomach to the brain.
Researchers report personality traits and psychological health impact how we value personal control when making decisions. The study reports brain activity in the motivation system is dampened in those with passive personalities and depression when we receive rewards that we have earned or feel in personal control of situations.
Researchers shed light on the role dopamine neurons play in assigning values to transient environmental cues that drive behaviors.
Researchers have developed a sensor that can detect early stage Parkinson's disease by analyzing a sample of a patient's breath.
Researchers have developed new neural implants that enable targeted delivery of drugs deep into brain structures.
A family with a rare genetic mutation are helping researchers answer important questions about how the human brain is wired. The family, who share an altered copy of the DCC gene, have less connectivity between areas where dopamine neurons originate and their target sites.
People exposed to two common agrochemicals, Paraquat and Maneb, are at a 250% higher risk of developing Parkinson's disease, researchers report.
According to researchers, dopamine neurons may play a key role in the formation of episodic memory. The findings could help in the development of new treatments for neurodegenerative disorders that affect memory.
Researchers report the accumulation of glycosphingolipids in the substantia nigra appears to be elevated in Parkinson's disease patients. The finding could be used as a biomarker for helping diagnose Parkinson's before symptoms of the disease set in.
