Kinesthetic motor imagery and actual execution of movements share a common neural circuitry. Functional magnetic resonance imaging was used in 12 right-handed volunteers to study brain activity during motor imagery and execution of simple and complex unimanual finger movements of the dominant and the nondominant hand. In the simple task, a flexible object(More)
Parkinson's disease (PD) is a common neurodegenerative disorder characterized by a selective loss of dopaminergic neurons in the substantia nigra (SN). It has been suggested that microglial inflammation augments the progression of PD. Neuromelanin (NM), a complex polymer pigment found in catecholaminergic neurons, has sparked interest because of the(More)
Alpha-Synuclein (alpha-Syn) accounts, as a major component of Lewy bodies (LB), for the filamentous deposits in many cases of neurodegenerative diseases. Yet, little is known about the molecular mechanisms of neuronal loss in these diseases. The correlation between alpha-Syn oligomerization/aggregation and pathologies raises the key question of which(More)
OBJECTIVES In multiple sclerosis, an autoimmune inflammatory disease, oligodendroglia are primarily affected and play an important role in the onset and process of the degeneration of neuronal axons. High-dose therapy with glucocorticoids like 6alpha-methylprednisolone (MP) as well as the application of immunomodulatory agents like glatiramer acetate (GA)(More)
