Evaluation of striatonigral connectivity using probabilistic tractography in Parkinson's disease
The cardinal movement abnormalities of Parkinson's disease (PD), including tremor, muscle rigidity, and reduced speed and frequency of movements, are caused by degeneration of dopaminergic neurons in the substantia nigra that project to the putamen, compromising information flow through frontal-subcortical circuits. Typically, the nigrostriatal pathway

Magnetic Resonance-guided Focused UltraSound (MRgFUS) offers an incisionless approach to treat essential tremor (ET). Due to lack of evident internal anatomy on traditional structural imaging, indirect targeting must still be used to localize the lesion.

White matter integrity assessed by diffusion tensor tractography in a patient with a large tumour mass but minimal clinical and neuropsychological deficits [PDF]
Diffusion tensor imaging (DTI) tractography and image registration were used to investigate a patient with a massive left-sided brain tumor, whose size was largely disproportionate to his subtle neurological deficits.

Comparative mouse brain tractography of diffusion magnetic resonance imaging
Diffusion magnetic resonance imaging (dMRI) tractography can be employed to simultaneously analyze three-dimensional white matter tracts in the brain.

In this chapter we describe the underlying principles and most common techniques in diffusion tractography. We cover deterministic streamline tractography and several different probabilistic approaches. We aim to provide a conceptual understanding of the

Summary: Superficial white matter (SWM) supports local cortico-cortical communication. Still, its whole-brain organization remains difficult to characterize in vivo, due to its short length, high curvature, proximity to the gray-white matter interface ...

Probabilistic Tractography for Complex Fiber Orientations with Automatic Model Selection
Fiber tractography aims to reconstruct white matter (WM) connections in the brain. Challenges in these reconstructions include estimation of the fiber orientations in regions with multiple fiber populations, and the uncertainty in the fiber orientations as a result of noise.
