A new study reports there is no evidence that gadolinium contrast material, commonly used for MRI scans, contributes to cognitive decline.
New findings about dopaminergic neurons in the striatum could have implications for treating Parkinson's disease and Tourette syndrome.
Choice bias is a byproduct of learning from reward, a new study reports.
N-acetylcysteine appears to help enable dopamine neurons to recover some function, researchers report.
Researchers hypothesize vitamin B1 (thiamine) deficiency may play a significant role in dementia associated with alcohol use disorder. It is known iron deposits in the brain contribute to neurodegenerative diseases. Those with AUD have elevated levels of both iron in their blood and thiamine deficiency. Thiamine is vital for maintaining the blood-brain barrier. Thiamine deficiency associated with AUD disrupts the integrity of the BBB, allowing for more iron deposits within the brain and leading to oxidative tissue damage.
Researchers use neuroimaging technology to visualize the pathways that connect the different areas of the basal ganglia. The research could lead to new tracking of disease progression in Parkinson's and Huntington's disease.
Researchers report the striatum acts as a sensory hub which integrates various types of sensory information.
Patients who suffer from frontotemporal dementia with extrapyramidal symptoms have brainstem atrophy and reduced metabolic activity in specific brain regions compared to those with FTD without extrapyramidal symptoms.
Researchers have developed a new theory of how developmental math disability occurs.
Researchers have successfully recorded neural activity in the human striatum.
