A 55-year-old woman has received treatment for years to manage a chronic, progressive disease. Since her mid-40s the patient has had difficulty initiating movements. She has a shuffling gait, an expressionless face, and tremor in her hands and fingers at rest. Over the years she has tried many medications but with little relief of her symptoms, and instead has experienced severe adverse effects. She is referred for possible ablation surgery. The neurosurgeon explains the different pathways involved in initiation and inhibition of movement, the foundation of her disease. The neurosurgeon explains that by nullifying or accentuating some of the pathways, some of her symptoms may be alleviated.
The introduction of an ablative lesion into which structure labeled in the image would be expected to improve this patient’s bradykinesia?
A. A
B. B
C. C

Thank you for this article. I would also like to talk about the fact that it can end up being hard when you find yourself in school and just starting out to create a long credit score. There are many students who are only trying to pull through and have an extended or beneficial credit history are often a difficult thing to have.
