Dopamine neurons connect subregions of the striatum that contribute to habit formation. The findings shed new light on how habits are formed, and how they can be broken.
The subthalamic nucleus in the brain communicates with the motor system to help the body stop an action, researchers confirm.
Consuming seven or more units of alcohol per week is associated with increased iron levels in the brain. Higher levels of iron in the brain is linked to increased risk of neurodegenerative disorders and alcohol-related cognitive decline.
Researchers identified a brain region responsible for driving action, and another that suppresses action. The study reports impulsive behaviors can be triggered or suppressed by activating these areas.
Takotsubo syndrome, a sudden form of acute heart failure often brought on by emotional or physical stress, is associated with changes in brain regions associated with emotion and emotional processing.
Neurons in the parafascicular thalamus project to three different parts of the basal ganglia. Targeting these circuits could be a new target for treating motor dysfunction and depression associated with Parkinson's disease.
Researchers propose a new framework for three seemingly unconnected forms of creativity.
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.
