To compare changes in signal intensity (SI) ratios of the dentate nucleus (DN) and globus pallidus (GP) to those other structures on unenhanced T1-weighted magnetic resonance (MR) images between linear macrocyclic gadolinium-based contrast agents (GBCAs).The study was approved by ethical committee University Heidelberg (reference no. S-324/2014). Owing retrospective character study, did not require any written informed consent. Two groups 50 patients who underwent at least six consecutive MR...
Objective The aim of this study was to compare changes in the signal intensity (SI) ratio dentate nucleus (DN) pons, DN cerebrospinal fluid (CSF), and globus pallidus (GP) thalamus on unenhanced T1-weighted magnetic resonance imaging (MRI) scans after serial injections macrocyclic gadolinium-based contrast agent gadobutrol. Materials Methods Thirty patients who had received at least 5 MRI examinations (plus an additional last for reference) with exclusive use gadobutrol, resulting a total...
Abstract Web-based data collection is increasingly popular in both experimental and survey-based research because it flexible, efficient, location-independent. While dedicated software for laboratory-based experimentation online surveys commonplace, researchers looking to implement experiments the browser have, heretofore, often had manually construct their studies’ content logic using code. We introduce , a free, open-source experiment builder that makes easy build studies in-laboratory...
The aim of this study was to compare changes in signal intensity (SI) ratios the dentate nucleus (DN) pons and cerebrospinal fluid (CSF) on unenhanced T1-weighted magnetic resonance imaging (MRI) scans between first last MRI using linear gadolinium-based contrast agent gadobenate dimeglumine.The approved by ethical committee University Heidelberg (S-324/2014), written informed consent waived due retrospective character study. Fifty patients who underwent at least 5 consecutive examinations...
To correlate histopathologic findings from biopsy specimens with their corresponding location within enhancing areas, non-enhancing areas and necrotic on contrast enhanced T1-weighted MRI scans (cT1).In 37 patients newly diagnosed glioblastoma who underwent stereotactic biopsy, we obtained a correlation of 561 1mm3 position the intraoperative cT1 image at 1.5 Tesla. Biopsy points were categorized as (CE), (NE) or (NEC) tissue samples "viable tumor cells", "blood" "necrotic (with without...
Purpose To determine the effect of more than 20 serial injections macrocyclic gadolinium-based contrast agents (GBCAs) on signal intensity (SI) dentate nucleus (DN) unenhanced T1-weighted magnetic resonance (MR) images. Materials and Methods In this retrospective, institutional review board-approved study, 33 patients who underwent at least consecutive MR imaging examinations (plus an additional for reference) with exclusive use GBCAs gadoterate meglumine gadobutrol were analyzed. SI ratio...
Recent studies reported an increase in the dentate nucleus (DN)-to-pons signal intensity (SI) ratio (DN-pons SI ratio) on unenhanced T1-weighted images patients who received consecutive serial injections of linear gadolinium-based contrast agents (GBCAs). In contrast, most found no DN-pons when were treated with macrocyclic GBCAs. However, potential difference between and GBCAs has never been assessed individuals subsequent applications both agents. this retrospective study, we evolution...
Abstract Recently, it has been suggested that people are spontaneously inclined to cooperate in social dilemmas, whereas defection requires effortful deliberation. From this assumption, we derive should entail more cognitive conflict than cooperation. To test hypothesis, the current study presents a first application of response dynamics paradigm (i.e., mouse-tracking) dilemmas. In fully incentivized lab experiment, mouse movements were tracked while participants played simple two-person...

Mouse-tracking – the analysis of mouse movements in computerized experiments is becoming increasingly popular psychological research. Mouse are taken as an indicator commitment to or conflict between choice options during decision process. Using mouse-tracking, researchers have gained insight into temporal development cognitive processes across a growing number domains. In this chapter, we present software that offers users easy and convenient means recording analyzing their First, introduce...
Background and Purpose Due to its sensitivity deoxyhemoglobin, susceptibility weighted imaging (SWI) enables the visualization of deep medullary veins (DMV) in patients with acute stroke, which are difficult depict under physiological circumstances. This study assesses asymmetric appearance prominent DMV as an independent predictor for stroke severity outcome. Materials Methods SWI 86 middle cerebral artery (MCA) were included. A scoring system from 0 (no visible DMV) 3 (very was applied...
Objective Several studies have analyzed a correlation between the apparent diffusion coefficient (ADC) derived from diffusion-weighted MRI and tumor cellularity of corresponding histopathological specimens in brain tumors with inconclusive findings. Here, we compared large dataset ADC values stereotactic biopsies glioblastoma patients using new postprocessing approach including trajectory analysis automatic nuclei counting. Materials Methods Thirty-seven newly diagnosed glioblastomas were...
Abstract This study examined the relation between conservatism and life satisfaction. Analyses based on data from a representative German survey (ALLBUS 2010) revealed positive self‐reported satisfaction, thus supporting prior claims of this link. Different accounts have been proposed for relationship, suggesting system justification, adjustment, or multiple group membership as potential mediators. Going beyond research, allowed comparison these different mechanisms. that justification one...
Movement tracking is a novel process-tracing method that promises unique access to the temporal dynamics of psychological processes. The involves high-resolution hand or handheld device (e.g., computer mouse) while it used make choice. In contrast other methods, which mostly focus on information acquisition, movement focuses processes integration and preference formation. this article, we present tutorial with mousetrap R package. We address all steps research process, from design...
Over the past decades, there has been considerable interest in individual differences cooperative behaviour and how these can be explained. Whereas Honesty–Humility dimension from HEXACO model of personality identified as a consistent predictor cooperation, underlying motivational mechanisms this association have remained unclear—especially given confound between temptation to exploit others fear being exploited drivers defection social dilemmas. In reanalysis new experiment, we tease apart...
Abstract From an embodiment perspective, action and cognition influence each other constantly. This interaction has been utilized in mouse-tracking studies to infer cognitive states from movements, assuming a continuous manifestation of processing into movement. However, it is mostly unknown how this affected by the variety possible design choices paradigms. Here we studied three factors impact movement Simon task with mouse tracking. We varied response selection (i.e., or without clicking),...
Abstract Judgments and decisions can rely on rules to integrate cue information or the retrieval of similar exemplars from memory. Research exemplar-based processes in judgment has discovered several task variables influencing dominant mode processing. This research often aggregates data across participants classifies them as using either cue-based It been argued for theoretical empirical reasons that both kinds might operate together parallel. Hence, a classification strategies may be...
