The cause of this disease appears to be brought on by the progressive inability to produce adequate dopamine in the brain. People that suffer with ParkinsonĄ¯s have reported REM sleep disruption at the onset of the condition. This paper reviews several animal model lesion studies related to the Pedunculopontine Nucleus, and how it plays a role in sleep regulation following a decline in dopamine production in those with parkinsonian conditions. The goal of this paper is to elucidate the functioning of the PPN and explain the nucleiĄ¯s possible role in the onset and progression of parkinsonian conditions in animal models. %K ParkinsonĄ¯s Disease %K Neurodegeneration %K REM %K Sleep Change %K Dopamine %K Substantia Nigra %K Systems %K PPN %K PTN %K Pedunculopontine %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=74425
