Trigeminal neuralgia (TN) is supposedly caused by an ectatic blood vessel affecting the trigeminal nerve at the root entry zone of the brain stem. Recent evidence suggests an additional central component within trigeminal pain-processing in the pathophysiology of TN. Therefore, we aimed to identify specific brain regions possibly associated with the(More)
BACKGROUND Pathogenic autoantibodies targeting the recently identified leucine rich glioma inactivated 1 protein and the subunit 1 of the N-methyl-D-aspartate receptor induce autoimmune encephalitis. A comparison of brain metabolic patterns in 18F-fluoro-2-deoxy-d-glucose positron emission tomography of anti-leucine rich glioma inactivated 1 protein and(More)
The effects of Parkinson's disease (PD) on action selection in conflictual situations were examined in an experiment using the flanker task in combination with event-related brain potentials (ERPs). More specifically, we investigated the effects of PD on behavioral and neuronal indicators of both instantaneous (within-trial flanker congruency effects) and(More)
BACKGROUND Pantothenate Kinase-Associated Neurodegeneration (PKAN) is a rare heritable disease marked by dystonia and loss of movement control. In contrast to the well-known "Eye-of-the-Tiger" sign affecting the globus pallidus, little is known about other deviations of brain morphology, especially about grey matter changes. METHODS We investigated 29(More)
Intranasal insulin has been the subject of attention not only with respect to enhancing memory processes, but also for its anorexic effects, as well as its effects on olfactory sensitivity. In the present study, the influence of intranasal insulin on gustatory sensitivity was investigated using intranasal applications of insulin or placebo in a double-blind(More)
OBJECTIVE The study was designed to examine persistent (input selection) versus transient (input shifting) mechanisms of attention control in Parkinson's disease (PD). METHOD The study identifies behavioral and neural markers of selective control and shifting control using a novel combination of a flanker task with an attentional set-shifting task, and it(More)
BACKGROUND To look for microstructural white matter alterations in patients with dystonia due to Pantothenate Kinase-Associated Neurodegeneration. MATERIAL AND METHODS We examined 21 genetically confirmed patients and an age-matched group of 21 healthy controls by diffusion tensor imaging. Evaluation of data was performed by tract-based spatial statistics(More)
Obesity is a major health concern in modern societies. Although decreased physical activity and enhanced intake of high-caloric foods are important risk factors for developing obesity, human behavior during eating also plays a role. Previous studies have shown that distraction while eating increases food intake and leads to impaired processing of food(More)
Background: Pathogenic autoantibodies targeting the recently identified leucine rich glioma inactivated 1 protein and the subunit 1 of the N-methyl-D-aspartate receptor induce autoimmune encephalitis. A comparison of brain metabolic patterns in F-fluoro-2-deoxy-d-glucose positron emission tomography of anti-leucine rich glioma inactivated 1 protein and(More)
This fMRI study intended to establish 3D-simulated mazes with olfactory and visual cues and examine the effect of intranasally applied insulin on memory performance in healthy subjects. The effect of insulin on hippocampus-dependent brain activation was explored using a double-blind and placebo-controlled design. Following intranasal administration of(More)
