Quantitative susceptibility mapping (QSM) is a novel technique which allows determining the bulk magnetic distribution of tissue in vivo from gradient echo resonance phase images. It commonly assumed that paramagnetic iron predominant source variations gray matter as many studies have reported reasonable correlation with brain concentrations vivo. Instead performing direct comparisons, however, all these used putative hallmark study by Hallgren and Sourander (1958) for their analysis....
Abstract Cortical activity in the EEG alpha band has proven to be particularly sensitive creativity‐related demands, but its functional meaning context of creative cognition not been clarified yet. Specifically, increases (i.e., synchronisation) response thinking can interpreted different ways: As a correlate cortical idling, as sign internal top‐down or, more specifically, selective inhibition brain regions. We measured during two studies employing neurophysiological measurement methods...
This fMRI study investigated brain activation during creative idea generation using a novel approach allowing spontaneous self-paced and expression of ideas. Specifically, we addressed the fundamental question what processes are relevant for genuinely new ideas, in contrast to mere recollection old ideas from memory. In general, (i.e., divergent thinking) was associated with extended activations left prefrontal cortex right medial temporal lobe, deactivation temporoparietal junction. The as...
Abstract As it is the case in brainstorming, each single idea a person generates to specific problem may stimulate new ideas or solutions others. In this fMRI study, we investigate effects of cognitive stimulation via exposure other people's on originality generated ideas. Participants are requested generate alternative uses conventional everyday objects subsequent short intervention which they exposed ideas, were either common highly original. control condition, meaningless pseudowords...
Neuroimaging studies have revealed a strong link between mental calculation and the angular gyrus (AG) which has been interpreted to reflect arithmetic fact retrieval. Moreover, stronger AG activation in individuals with higher mathematical competence reported. The present fMRI study investigates specificity of for learning interplay training on brain activation. Adults lower underwent five-day sets complex multiplication figural-spatial problems. In following test session, trained untrained...
Abstract While the left angular gyrus (lAG) has been repeatedly implicated in mental arithmetic, its precise functional role not established. On one hand, it speculated that lAG is involved task‐specific processes. other observation of relative deactivation during arithmetic led to contention differential activation reflects task‐unrelated difficulty effects associated with default mode network (DMN). Using magnetic resonance imaging, we investigated neural correlates associative confusion...
Responsiveness to food cues, especially those associated with high-calorie nutrients may be a factor underlying obesity. An increased motivational potency of foods appears mediated in part by the hippocampus. To clarify this, we investigated means 3-T magnetic resonance imaging (MRI) activation hippocampus and brain structures response pictures low-calorie 12 obese normal-weight adolescents. investigate relationship between neuronal patterns (e.g., hippocampus) caloric content images plasma...
Abstract Recent advances in deep learning and natural language processing (NLP) have opened many new opportunities for automatic text understanding the medical field. This is of great benefit as clinical downstream tasks rely on information from unstructured documents. However, low-resource languages like German, use modern applications that require a large amount training data proves to be difficult, only few sets are available mainly due legal restrictions. In this study, we present an...
The fractal dimension (FD) can be used as a measure for morphological complexity in biological systems. aim of this study was to test the usefulness quantitative parameter context cerebral vascular complexity. Fractal analysis applied on ten patients with arteriovenous malformations (AVM) and healthy controls. Maximum intensity projections from Time-of-Flight MRI scans were analyzed using different measurements FD, Box-counting dimension, Minkowski generalized dimensions evaluated by means...
Information on microstructural white matter integrity has been shown to explain post-stroke recovery beyond clinical measures and focal brain damage. Especially, knowledge about early changes might improve prediction of outcome. We investigated 42 acute reperfused ischemic stroke patients (mean age 66.5 years, 40% female, median admission NIHSS 9.5) with a symptomatic MRI-confirmed unilateral middle cerebral artery territory infarction 24-72 h after 3 months. All underwent neurological...
Background: Applications of artificial intelligence (AI) are finding their way into many areas society, including healthcare and show potential in this domain. To evaluate these new technologies use them wisely, professionals need to integrate AI literacy curricula a meaningful way, as they do other academic fields. Objectives: The aim paper is share initial experiences the didactic implementation an online course health professions education that designed strengthen community acquiring...
The neural efficiency hypothesis postulates an inverse relationship between intelligence and brain activation. Previous research suggests that gender task modality represent two important moderators of the phenomenon. Since most existing studies on have used ERD in EEG as a measure activation, central aim this study was more detailed analysis phenomenon by means functional MRI. A sample 20 males females, who had been screened for their visuo-spatial intelligence, confronted with mental...
The aim of the present functional magnetic resonance imaging (fMRI) study at 3 T was to investigate influence verbal-visual cognitive style on cerebral activation patterns during mental arithmetic. In domain arithmetic, a visual might for example mean visualize numbers and (intermediate) results, verbal mean, that results are verbally repeated. this study, we investigated, first, whether verbalizers show activations in areas language processing, visualizers processing Some researchers have...
