The purpose of this study was to investigate the fMRI response of the sensorimotor cortex to a vibration paradigm produced by a novel vibrotactile stimulator. Fifteen contiguous slices covering the sensorimotor cortex parallel to the anterior (AC) and posterior commissure (PC) line were obtained with echoplanar magnetic resonance imaging at 1.5T. Cortical(More)
The aim of the study was to implement a vibrotactile stimulator using functional magnetic resonance imaging (fMRI). A fMRI compatible vibration device consisting of a pneumatically driven dual membrane pump was developed. Brain activation during 50 Hz vibrotactile stimulation of the right hand-palm were compared to a right 2 Hz finger-to-thumb-tapping in(More)
This article provides an overview of recent research on human planning and problem solving. As an introduction, these two cognitive domains will be described and discussed from the perspective of experimental and cognitive psychology. The following sections will focus on the role of the prefrontal cortex in planning and problem solving and on disorders of(More)
Mild cognitive impairment has frequently been reported for patients in the early stages of multiple sclerosis. The aim of the present study was to measure whether altered cortical activation during a sustained attention task occurs along with limited extent of neuropsychological problems. Expanded brain activation of multiple sclerosis patients with normal(More)
The test-retest reliability of activation patterns elicited by encoding and recognition of word-pair associates within the whole brain and a predefined medial temporal region of interest (ROI) was investigated. Twenty healthy right-handed subjects were studied within two sessions, either on the same day or 210-308 days later. Three quantitative measures of(More)
Despite the large number of behavioral and functional neuroimaging studies employing the Tower of London (ToL), the task's structural parameters and particularly their impact on planning have not been addressed so far. In this paper, we highlight the structural properties of ToL problems and provide evidence for their systematic and substantial effects on(More)
The Tower of London (ToL) test is widely used for measuring planning and aspects of problem solving. The primary focus of this study was to asses the relationship among different measures on the ToL. A secondary purpose was to examine the putative relationship between intelligence and working memory with that of ToL performance. Analyses of the(More)
In clinical and experimental settings, planning ability is typically assessed using the Tower of London (ToL) or one of its variants. For enhancing the comparability across studies, a common ToL problem set was recently suggested comprising a collection of 4- to 7-move problems. Based on previous theoretical and empirical analyses of problem space and task(More)
PURPOSE To analyse prognostic factors for long term seizure remission in patients with childhood (CAE) and juvenile absence epilepsy (JAE). STUDY DESIGN A retrospective analysis of a hospital based prevalence cohort. METHODS The cohort consisted of 163 patients (104 females, 59 males) treated at the Universitatsklinik fur Neurologie, Innsbruck between(More)
Gender-related differences in brain activation patterns and their lateralization associated with cognitive functions have been reported in the field of language, emotion, and working memory. Differences have been hypothesized to be due to different cognitive strategies. The aim of the present study was to test whether lateralization of brain activation in(More)
