A new study reports neuromelanin sensitive MRI is able to measure dopamine function associated with psychosis.
A new neuroimaging study reveals 12 people with documented post-treatment Lyme disease syndrome have an elevation of a chemical marker associated with neuroinflammation. The findings could help develop new treatments for the pain, fatigue and brain fog associated with PTLDS.
A new study reveals women's brain tend to appear three years younger than males of the same age. Researchers report this could be a reason why women tend to remain mentally sharp longer than men.
A new study reveals the role dopamine plays in controlling eating behaviors. Researchers found when people crave specific foods, the brain releases more dopamine when they finally consume the item. The study reports the gastrointestinal tract is in constant contact with the brain and uses reward stimuli to control our desire for food.
A new study has identified racial disparities between African Americans and Caucasians in the level of a key biomarker used to identify Alzheimer's disease.
A new machine learning algorithm was able to predict, with 98% accuracy, which patients would develop Alzheimer's disease, six years prior to diagnosis by analyzing PET brain scans.
Upon eating, dopamine is released in the brain at two different times, during ingestion and when the food reaches our stomach, researchers report.
Researchers argue consciousness may be caused by the way the brain generates energetic feedback loops.
A new neuroimaging study reveals methylphenidate, better known as Ritalin, increases the level of dopamine available in the caudate. Along with increased dopamine levels, researchers also notice greater functional connectivity between the prefrontal cortex, hippocampus and precuneus, three areas of the brain associated with memory and attention.
A new study reveals a brain region that contributes to anhedonia, the loss of pleasure, in those with depression. The study also shows how ketamine acts on this brain region, explaining why the drug appears to be so effective at treating anhedonia.
A new study reveals common brain activity patterns associated with depressive moods.
A new convolutional neural network uses PET brain scans to detect biological signs of Alzheimer's disease years before the symptoms appear, researchers report.
