10 Questions
What is the primary function of the Basal Ganglia in terms of motor movement?
Picks the correct movements
What is the role of the Cognitive Loop in the Basal Ganglia?
Task switching and priority setting
What is the main pathological characteristic of Parkinson's disease in the Basal Ganglia?
Cell death in the substantia Nigra, leading to dopamine depletion
What is the relationship between dopamine and the motor cortex?
Dopamine is the main driver of motor cortex activation
What is the significance of the appearance of TRACT symptoms in Parkinson's disease patients?
