Huntington's disease may progress to advanced stages as a result of degradation of the cells' health maintenance system than due to the increased disease pathology itself.
Astrocytes in the striatum appear to play a critical role in stuttering. Researchers found treatment with risperidone helped reduce stuttering by increasing the metabolism of striatal astrocytes.
Researchers recorded alterations in levels of both dopamine and serotonin in the brain when people perform perception and decision making based tasks.
Researchers found specific neurons in the striosome that help mice learn to avoid negative experiences.
Study reports the putamen, not just the cortex, contributes to the brain's ability to multitask.
Dopamine receptors have different molecular features and functions depending on their anatomical location within the striatum. The findings could help develop better-targeted treatments for a range of disorders from schizophrenia to Parkinson's disease.
During memory tasks, people with psychosis have different patterns of activity in the prefrontal and mediotemporal brain areas compared to those without the disorder. When exposed to cannabidiol (CBD), the activity of the brain areas became more like those seen in the controls for people with psychosis. Patients reported a decrease in symptoms of psychosis following one dose of CBD. Researchers stress that no definitive conclusions could be made about the effectiveness of CBD use over a sustained period.
