TL;DR: The encouraging finding that most state-of-the-art algorithms produce tractograms containing 90% of the ground truth bundles (to at least some extent) is reported, however, the same tractograms contain many more invalid than valid bundles, and half of these invalid bundles occur systematically across research groups.
Journal ArticleDOI
The origin of segmentation motor activity in the intestine.

TL;DR: It is demonstrated that typical segmentation can occur after total nerve blockade and phase amplitude modulation of the slow waves points to an underlying system of coupled nonlinear oscillators originating in ICC.
Journal ArticleDOI
Sensorimotor and Pain Modulation Brain Abnormalities in Trigeminal Neuralgia: A Paroxysmal, Sensory-Triggered Neuropathic Pain.

TL;DR: TN is associated with GM abnormalities in areas involved in pain perception, pain modulation and motor function, which may reflect increased nociceptive input to the brain, an impaired descending modulation system that does not adequately inhibit pain, and increased motor output to control facial movements to limit pain attacks.
Journal ArticleDOI
In vivo visualization of cranial nerve pathways in humans using diffusion-based tractography.
TL;DR: Detailed assessment of anatomy and the ability of overlaying the tracts onto anatomic magnetic resonance imaging scans is essential, particularly in the posterior fossa, to ensure that the tracts have been reconstructed with anatomic fidelity.

TL;DR: The results demonstrate fundamental ambiguities inherent to tract reconstruction methods based on diffusion orientation information, with critical consequences for the approach of diffusion tractography in particular and human connectivity studies in general.
