In the present study, we were interested in the neurofunctional representations of ambiguity processing by using functional magnetic resonance imaging (fMRI). Twelve right-handed, healthy adults aged between 21 and 29 years (6 male, 6 female) underwent an ambiguity resolution task with 4 different conditions (dominant vs. non-dominant; dominant vs.(More)
OBJECTIVES This quantitative angiographic and intravascular ultrasound study determined the mechanisms of acute lumen enlargement and recurrent restenosis after rotational atherectomy (RA) with adjunct percutaneous transluminal coronary angioplasty in the treatment of diffuse in-stent restenosis (ISR). BACKGROUND In-stent restenosis remains a significant(More)
BACKGROUND AND PURPOSE The space-occupying effect of cerebral edema limits survival chances of patients with severe ischemic stroke. Besides conventional therapies to reduce intracranial pressure, hemicraniectomy can be considered as a therapeutic option after space-occupying cerebral infarction. There is controversy regarding the use of this method in(More)
The aim of the present study was to determine whether processing of syntactic word information (lemma) is subserved by the same neural substrate as processing of conceptual or word form information (lexeme). We measured BOLD responses in 14 native speakers of German in three different decision tasks, each focussing specifically on one level of lexical(More)
Neurofunctional alterations in acute posttraumatic stress disorder (PTSD) and changes thereof during the course of the disease are not well investigated. We used functional magnetic resonance imaging to assess the functional neuroanatomy of emotional memory in surgical patients with acute PTSD. Traumatic (relative to non-traumatic) memories increased neural(More)
Cortical activation by Yamamoto new scalp acupuncture in the treatment of patients with a stroke: a sham-controlled study using functional MRI Yamamoto new scalp acupuncture (YNSA) was fi rst introduced 37 years ago. 1 Today, it is the most frequently used microsystem in acupuncture next to auriculotherapy. Benefi ts associated with YNSA have been shown in(More)
Due to the widespread use of stents in complex coronary lesions, stent restenosis represents an increasing problem, for which optimal treatment is under debate. "Debulking" of in-stent neointimal tissue using percutaneous transluminal rotational atherectomy (PTRA) offers an alternative approach to tissue compression and extrusion achieved by balloon(More)
Neuroimaging research on the neurobiology of chronic PTSD (posttraumatic stress disorder) has revealed structural and functional alterations primarily affecting areas of the medial temporal lobe (hippocampus, amygdala, and parahippocampal gyrus) and the frontal cortex known to be associated with the disorder. Using functional magnetic resonance imaging(More)
Das seltene Krankheitsbild der primär progressiven Aphasie ist durch eine progrediente Sprachstörung gekennzeichnet, bei der recht häufig Wortfindungsstörungen das initiale Symptom darstellen. Die Sprachstörung bleibt über mehrere Jahre das führende und oft auch einzige Symptom. Andere kognitive Funktionen wie Gedächtnis, Orientierung, Urteilsvermögen oder(More)
Primary progressive aphasia is a rare disease characterised by slow deterioration of language, which remains the leading symptom whereas other cognitive functions such as memory, orientation, judgement, and visual-spatial skills are relatively spared and mostly not affected until 5 to 7 years after disease onset. Structural imaging displays atrophy of the(More)
