This fMRI study analyzes inferences on other persons' traits, whereby half of the participants were given spontaneous ("read") instructions while the other half were given intentional ("infer the person's trait") instructions. Several sentences described the behavior of a target person from which a strong trait could be inferred (trait diagnostic) or not(More)
This study explores the fMRI correlates of observers making trait inferences about other people under conflicting social cues. Participants were presented with several behavioral descriptions involving an agent that implied a particular trait. The last behavior was either consistent or inconsistent with the previously implied trait. This was done under(More)
Although many neuroimaging studies have considered verbal and visual short-term memory (STM) as relying on neurally segregated short-term buffer systems, the present study explored the existence of shared neural correlates supporting verbal and visual STM. We hypothesized that networks involved in attentional and executive processes, as well as networks(More)
Mental rotation tests traditionally show a male performance advantage. Some neuroimaging studies have reported sex-specific cortical activation patterns during mental rotation. However, these experiments used abstract stimuli and some studies did not systematically exclude performance as a confounding variable. The mental rotation of hands and hand-related(More)
To investigate the hypothesis that in multilingual speakers different languages are represented in distinct brain regions, 12 multilingual right-handed men performed a word fluency task, a picture naming task, a comprehension reading task, and their respective control tasks in three languages (Dutch, French, and English) while whole-head functional magnetic(More)
OBJECTIVES We sought to evaluate the benefit of 3 T compared with 1.5 T during presurgical functional magnetic resonance imaging. MATERIALS AND METHODS Six participants performed a motor, a visual, and 2 language paradigms both at 1.5 and 3 T. The number of activated voxels, mean t-value, and assessment of language dominancy were compared between both(More)
Voluntary action - in particular the ability to produce desired effects in the environment - is fundamental to human existence. According to ideomotor theory we can achieve goals in the environment by means of anticipating their outcomes. We aimed at providing neurophysiological evidence for the assumption that performing actions calls for the activation of(More)
OBJECTIVE To identify neural networks associated with the use of a mirror to superimpose movement of 1 hand on top of a nonmoving contralateral hand (often referred to as mirror therapy or mirror-induced visual illusion). DESIGN A functional magnetic resonance imaging (fMRI) study of mirror-induced visual illusion of hand movements using a blocked design(More)
OBJECTIVES This study aimed to investigate whether different types of memory stimulus provide different information during the Wada or intracarotid amytal procedure (IAP) in patients with refractory medial temporal lobe epilepsy (MTLE). METHODS Eighty nine surgical candidates with documented MTLE and selected for left hemispheric language dominance(More)
The best established lateralized cerebral function is speech production, with the majority of the population having left hemisphere dominance. An important question is how to best assess the laterality of this function. Neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI) are increasingly used in clinical settings to replace the(More)
