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. Read More
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. Read More
Study reveals the role the Gao protein plays in a rare genetic movement disorder often diagnosed during infancy and early childhood. Read More
The decline of striosomal activity in the brain may explain why people lose the motivation to learn as they age. Read More
Researchers recorded alterations in levels of both dopamine and serotonin in the brain when people perform perception and decision making based tasks. Read More
The striatum and premotor cortex show altered patterns in neural activity when encoding time. The dynamics of the striatum were more sequential than those of the premotor cortex. Read More
Researchers found specific neurons in the striosome that help mice learn to avoid negative experiences. Read More
Study reports the putamen, not just the cortex, contributes to the brain's ability to multitask. Read More
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. Read More
Involuntary movements and tremors caused as a result of taking dopamine replacement medications for Parkinson's disease can be alleviated through the suppression of RasGRP1. Read More
Neuroimaging reveals how dopamine released from the striatum influences brain activity in the motor cortex and insular. Read More
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. Read More
