Abstract

The traditional model of corticostriatal-thalamocortical projections, with indirect and direct pathways, provides a simplified and useful explanation for the motor deficits (hypokinesia, bradykinesia) that develop in the course of sporadic Parkinson's disease. In the classic model, major emphasis is placed on the dopamine deficiency in the dorsal striatum that occurs as a result of neuronal loss in the substantia nigra of the midbrain. Nevertheless, because the pathological process that underlies Parkinson's disease also involves many key nondopaminergic connectivities, a revised model is needed that incorporates these projections. The focus on damage to nondopaminergic and extranigral sites is becoming increasingly important for clinical practice.

Alpha-Synuclein Aggregation (MDS)

Alpha-synucleins are small proteins that are believed to restrict the mobility of synpatic vesicles and inhibit neurotransmitter release. Aggregation of these proteins have been linked to several types of neurodegenerative diseases including dementia with Lewy bodies and Parkinson's disease. Here is the latest research on α-synuclein aggregation.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
