Scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility. PET imaging shows that the brain increases dopamine production when completing cognitively demanding ...

World Parkinson's Disease Day is observed to raise awareness about this progressive neurological disorder that affects millions of people worldwide. This article helps to understand the symptoms, ...

They also performed PET scans to measure levels of the brain chemical dopamine and different types of dopamine receptors, which are involved in focus and concentration. "We thought that the amount ...

World Parkinson’s Disease Day is observed on April 11 around the globe to raise awareness about the progressive neurological disorder ...

researchers were able to look at a substance called neuromelanin – a black pigment left behind in the brain that accumulates over time if there is too much dopamine. The neuromelanin appears in the ...

This can be demonstrated by special imaging such as positron emission tomography (PET) and dopamine transporter imaging (DAT-SPECT). MRI may be also helpful in differentiating PD from atypical ...

PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more efficiently the tasks are completed.
