MR-Encephalography (MREG) is a technique that allows real time observation of functional changes in the brain that appears within 100 msec. The high sampling rate is achieved at the cost of some spatial resolution. The article describes a novel imaging method for fast three-dimensional-MR-encephalography whole brain coverage based on rosette trajectories(More)
Corrective saccades are small eye movements that redirect gaze whenever the actual eye position differs from the desired eye position. In contrast to various forms of saccades including pro-saccades, recentering-saccades or memory guided saccades, corrective saccades have been widely neglected so far. The fMRI correlates of corrective saccades were studied(More)
Die Eliminationsrate der Enzyme ALD, CPK, GLDH, GOT, GPT, LDH und MDH sowie die Eliminationsraten der Isoenzyme von GOT, MDH und LDH werden an cinem ausgesuchten Patientengut untersucht. Die langsamste Elimination aus der Blutbahn zeigt das Isoenzym LDH1, es folgen GPT, ALD, GLDH, MDH, CPK und LDH5. Die Ergebnisse werden mit den Angaben in der Literatur(More)
OBJECTIVES Affective dysregulation is a clinical hallmark of borderline personality disorder (BPD). This study used an instructed fear task combined with functional MRI (fMRI) and skin conductance response (SCR) to test hypotheses about mechanisms of disturbed fronto-limbic neural circuitry underlying dysfunctional emotional processing in BPD. METHODS(More)
Verbal social interaction plays an important role both in the etiology and treatment of psychiatric disorders. However, the neural basis of social interaction has primarily been studied in the individual brain, neglecting the inter-individual perspective. Here, we show inter-individual neuronal coupling of brain activity during live verbal interaction, by(More)
Motion stimuli in one visual hemifield activate human primary visual areas of the contralateral side, but suppress activity of the corresponding ipsilateral regions. While hemifield motion is rare in everyday life, motion in both hemifields occurs regularly whenever we move. Consequently, during motion primary visual regions should simultaneously receive(More)
The ability to pursue moving objects with the eyes is vital to humans. However, it remains unclear how the brain differentiates visual object motion, smooth pursuit eye movements (SPEM), and eye movement-induced relative motion on the retina and where visual-to-oculomotor transformation takes place. To characterize functional differences of SPEM-processing(More)
We applied remote sensing techniques using WorldView-2 images with high spatial resolution and field verification to map the bathymetry and benthic habitats of the Puerto Morelos Reef National Park in the Mexican Caribbean. These images were processed using the standardized physics-based data processing of EOMAP ́s Modular Inversion and Processing System(More)
BACKGROUND Dysfunction of central nervous pain processing is assumed to play a key role in primary fibromyalgia (FM) syndrome. This pilot study examined differences of pain processing associated with adopting different interpersonal perspectives. METHODS Eleven FM patients and 11 healthy controls (HC) were scanned with functional magnetic resonance(More)
Colchicine as well HOE 077 were found to be effective in the inhibition of hepatic collagen accumulation after bile duct ligation in rats. The effect was additive and was truly reflected by changes in the serum PIIIP and 7s-collagen (IV) concentration. Extrahepatic effects on collagen synthesis were not detected when HOE 077 was used. Thus further studies(More)
