Nickel appears to suppress the effect of the carbon burst; however, the nickel spark can be identified by tiny blocks of brilliant white light. Silicon suppresses the carbon burst even more than nickel. When silicon is present, the carrier line usually ends abruptly in a white flash of light.
The standard medication used to treat Parkinson's is Levodopa, a drug that initially has major benefits but can later also produce serious side effects in the form of involuntary, jerky movements. A research group at Lund University has now found a way to study what it is in the brain that causes these side effects.
Most drugs available for the treatment of Parkinson's disease work to imitate the effect of dopamine in the brain. That is because low dopamine levels in the brain have been linked to Parkinson's disease. These drugs are made to trick the brain into thinking it is receiving dopamine.
