In tests with laboratory animals, the Swedish scientists managed to stop the movements completely, having identified the area of the brain where the debilitating movements are activated as a side effect of the medication L-dopa...

Scientists told Sveriges Radio (SR) that the aim is now to develop new medication suitable for humans..


Up until now, scientists have believed that the involuntary movements are activated in a deep part of the brain, but the Lund University researchers have for the first time been able to demonstrate that it is the shallow parts of the brain that after several years of treatment become oversensitive to the Parkinson's disease medication.

With the help of advanced technology, they were able to track brain activity in rats with Parkinson's and could block the parts of the cerebral cortex that had become oversensitive to the medication.
