OBJECTIVE Studies in fibromyalgia syndrome with functional neuroimaging support the hypothesis of central pain augmentation. To determine whether structural changes in areas of the pain system are additional preconditions for the central sensitization in fibromyalgia we performed voxel based morphometry in patients with fibromyalgia and healthy controls.

Fibromyalgia syndrome (FMS) is characterized by widespread pain. Studies with functional neuroimaging support the hypothesis of central pain augmentation in FMS. We tested this in our study with a novel paradigm of tonic pain induced by a single stimulus. Tonic pain, in contrast to phasic pain, seems to be a more appropriate experimental approach to study(More)
Dissociative paralysis in conversion disorders has variably been attributed to a lack of movement initiation or an inhibition of movement. While psychodynamic theory suggests altered movement conceptualization, brain activation associated with observation and replication of movements has so far not been assessed neurobiologically. Here, we measured brain(More)
Hypnotic paralysis has been used since the times of Charcot to study altered states of consciousness; however, the underlying neurobiological correlates are poorly understood. We investigated human brain function during hypnotic paralysis using resting-state functional magnetic resonance imaging (fMRI), focussing on two core regions of the default mode(More)
INTRODUCTION In this study, the activation of different brain areas after an experimental surgical incision was assessed by functional magnetic resonance imaging, and the pathophysiological role of distinct brain activation patterns for pain perception after incision was analyzed. METHODS Thirty male volunteers (mean age +/-SD, 25+/- 5 yr) received an(More)
Studies with functional neuroimaging support the hypothesis of central pain augmentation in fibromyalgia syndrome (FMS) with functional differences in areas of the medial pain system. To clarify whether these findings are unique to patients with FMS, BOLD-signal patterns during and before tonic experimental pain were compared to healthy controls and(More)
BACKGROUND/AIM This is the first investigation of the central processing of itch in the brain in 8 subjects with atopic dermatitis (AD) in comparison to 6 healthy controls (HC), comparing histamine-induced itch related activations in the frontal, prefrontal, parietal, cingulate cortex, thalamus, basal ganglia and cerebellum. METHODS We employed 1%(More)
OBJECTIVE Anticipation of pain influences its cerebral processing and dysfunctional cognitive style like catastrophizing correlates with the severity of pain. Patients with fibromyalgia syndrome (FMS) exhibit higher levels of catastrophizing, increased attention to pain, and augmented cerebral pain processing. Therefore, alteration in cerebral processing(More)
RATIONALE AND OBJECTIVES The combination of functional magnetic resonance imaging (fMRI) of the brain with multivariate pattern analysis (MVPA) has been proposed as a possible diagnostic tool. Goal of this investigation was to identify potential functional connectivity (FC) differences in the salience network (SN) and default mode network (DMN) between(More)
There are an increasing number of neuroimaging studies that allow a better understanding of symptoms, neural correlates and associated conditions of fibromyalgia. However, the results of these studies are difficult to compare, as they include a heterogeneous group of patients, use different stimulation paradigms, tasks, and the statistical evaluation of(More)
