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 report the optimal target for brain stimulation depends on the type of dystonia being treated.
Study reveals how brain areas work together to train and perform a practiced skill.
Inadequate sleep can harm brain organization in early adolescence, researchers report. The disorganization can have an impact on cognitive processes, including attention, memory, emotional regulation, and controlling behaviors.
Fine motor skills utilized by using tools engage parts of the brain similar to those mobilized when we think about the construction of a sentence, researchers report.
The old adage that practice makes perfect may very well be true, according to neuroscientists. Researchers found when a male zebra finch is in the presence of an attractive female and delivers its rehearsed mating call, a noradrenaline release in the basal ganglia shuts down variability in song and makes the call as perfect as it can be.
A new map of the basal ganglia provides a blueprint of the structure of the brain region and reveals a new level of influence connected to this area.
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.
A group of neurons located in the basal ganglia appears to play a vital role in cognitive flexibility.

Combining neuroimaging data with artificial intelligence, researchers have identified two distinct neuroanatomical subtypes of schizophrenia. The first, more typical subtype is associated with a lower widespread volume of gray matter compared to healthy controls. In the second subtype, gray matter volume is largely similar to healthy brains.
New findings about dopaminergic neurons in the striatum could have implications for treating Parkinson's disease and Tourette syndrome.
