Recent neuroimaging studies implicate nigrostriatal degeneration as a critical factor in producing late-onset parkinsonism in patients with l-dopa-responsive dystonia-causing mutations. However, postmortem anatomical studies do not reveal neurodegeneration in l-dopa-responsive dystonia patients. These contrasting findings make it unclear how parkinsonism

Circadian activity rhythms are jointly controlled by a master pacemaker in the hypothalamic suprachiasmatic nuclei (SCN) and by food-entrainable circadian oscillators (FEOs) located elsewhere. The SCN mediates synchrony to daily light-dark cycles, whereas FEOs generate activity rhythms synchronized with regular

Levodopa-induced dyskinesias (LID) are a prevalent side effect of chronic treatment with levodopa (L-DOPA) for the motor symptoms of Parkinson's disease (PD). It has long been hypothesized that serotonergic neurons of the dorsal raphe nucleus (DRN) are capable of L-DOPA
