BACKGROUND AND PURPOSE The goal of our study was to evaluate the sensitivity and specificity for Alzheimer disease of semiquantitative dynamic susceptibility contrast (DSC) MR imaging as compared with results of qualitative single-photon emission computed tomography (SPECT) in the same patients and with previously published semiquantitative SPECT results. METHODS Fifty subjects were studied: ...

Functional magnetic resonance imaging and repetitive transcranial magnetic stimulation (rTMS) were used to explore the pathophysiology of auditory/verbal hallucinations (AVHs). Sixteen patients with schizophrenia-spectrum disorder were studied with continuous or near continuous AVHs. For patients with intermittent hallucinations (N = 8), blood oxygenation level-dependent (BOLD) activation maps ...

When we walk in our environment, we readily determine our travelled distance and location using visual cues. In the dark, estimating travelled distance uses a combination of somatosensory and vestibular (i.e., inertial) cues. The observed inability of patients with complete peripheral vestibular failure to update their angular travelled distance during active or passive turns in the dark implie...

A 15 year old ambidextrous patient presented with left temporoparietal lesions after head trauma. Seizures associated with visual hallucinations of written words arose six months later. Electroencephalography showed spike and wave complexes with phase opposition over the left parietal area. On MRI a post-traumatic porencephalic lesion was seen in area 7 and the superior part of area 39 of Brodm...

In the present functional magnetic resonance imaging (fMRI) study, we investigated the role of different brain regions in separate aspects of mentalizing. Young females aged 18-19 years were asked to imagine a social situation and answer a question. Perspective, self and other, as well as content, emotion, and behavior, were varied. Activation was observed in the left precuneus, left temporopar...

Correction Following publication of our article [1], we became aware that the treatment protocol for the single-site group is incorrectly stated in the methods section. All patients in this group are stimulated over the left temporoparietal cortex (not over the temporoparietal cortex contralateral to the tinnitus percept). Using the same stimulation site for all patients in the single-site grou...
