  • Advanced Fiber Tracking in Early Acquired Brain Injury Causing Cerebral Palsy [EVIDENCE-BASED MEDICINE LEVEL 2]

    Lennartsson, F., Holmstrom, L., Eliasson, A.- C., Flodmark, O., Forssberg, H., Tournier, J.- D., Vollmer, B.
    13 Jan 2015 | 8:01 am
    BACKGROUND AND PURPOSE: Diffusion-weighted MR imaging and fiber tractography can be used to investigate alterations in white matter tracts in patients with early acquired brain lesions and cerebral palsy. Most existing studies have used diffusion tensor tractography, which is limited in areas of complex fiber structures or pathologic processes. We explored a combined normalization and probabilistic fiber-tracking method for more realistic fiber tractography in this patient group. MATERIALS AND METHODS: This cross-sectional study included 17 children with unilateral cerebral palsy and 24…
  • Preclinical Evaluation of the Thrombogenicity and Endothelialization of Bare Metal and Surface-Coated Neurovascular Stents [INTERVENTIONAL]

    Krajewski, S., Neumann, B., Kurz, J., Perle, N., Avci-Adali, M., Cattaneo, G., Wendel, H. P.
    13 Jan 2015 | 8:01 am
    BACKGROUND AND PURPOSE: Stent-assisted coiling is routinely used for the endovascular treatment of complex or wide-neck intracranial aneurysms. However, in-stent thrombosis, thromboembolic events, and ischemic complications remain a major concern associated with stent implants. Therefore, a novel low-profile neurovascular stent with a bare metal surface was investigated with regard to thrombogenicity and endothelialization and compared with the same stent coated with albumin or heparin. MATERIALS AND METHODS: The bare metal and heparin- or albumin-coated stents were loaded in heparin-coated…

  • Measurements of carotid intima media thickness in non-invasive high-frequency ultrasound images: the effect of dynamic range setting

    Mario Gaarder
    26 Jan 2015 | 4:00 pm
    Background: Carotid intima media thickness (CIMT) measured with ultrasound (US) is widely used as biomarker for arteriosclerosis and as surrogate endpoint in interventional studies to assess efficacy of drug therapies. Strict US protocols are necessary to ensure reproducibility. The range of US signal intensities used for image formation, the dynamic range (DR), is rarely reported in studies and little is known about its effect on CIMT measurements in humans. The purpose of this study was to quantify the impact of DR on measurements of CIMT. Methods: US was used to examine 313 carotid…

  • Unraveling the relationship between regional gray matter atrophy and pathology in connected white matter tracts in long-standing multiple sclerosis

    Martijn D. Steenwijk, Marita Daams, Petra J.W. Pouwels, Lisanne J. Balk, Prejaas K. Tewarie, Jeroen J. G. Geurts, Frederik Barkhof, Hugo Vrenken
    27 Jan 2015 | 8:40 pm
    Abstract IntroductionGray matter (GM) atrophy is common in multiple sclerosis (MS), but the relationship with white matter (WM) pathology is largely unknown. Some studies found a co-occurrence in specific systems, but a regional analysis across the brain in different clinical phenotypes is necessary to further understand the disease mechanism underlying GM atrophy in MS. Therefore, we investigated the association between regional GM atrophy and pathology in anatomically connected WM tracts. MethodsConventional and diffusion tensor imaging was performed at 3T in 208 patients with long-standing…
  • Making sense: Dopamine activates conscious self-monitoring through medial prefrontal cortex

    Morten Joensson, Kristine Rømer Thomsen, Lau M. Andersen, Joachim Gross, Kim Mouridsen, Kristian Sandberg, Leif Østergaard, Hans C. Lou
    27 Jan 2015 | 8:40 pm
    Abstract When experiences become meaningful to the self, they are linked to synchronous activity in a paralimbic network of self-awareness and dopaminergic activity. This network includes medial prefrontal and medial parietal/posterior cingulate cortices, where transcranial magnetic stimulation may transiently impair self-awareness. Conversely, we hypothesize that dopaminergic stimulation may improve self-awareness and metacognition (i.e., the ability of the brain to consciously monitor its own cognitive processes). Here, we demonstrate improved noetic (conscious) metacognition by oral…

    Hikaru Takeuchi, Yasuyuki Taki, Atsushi Sekiguchi, Hiroshi Hashizume, Rui Nouchi, Yuko Sassa, Yuka Kotozaki, Carlos Makoto Miyauchi, Ryoichi Yokoyama, Kunio Iizuka, Seishu Nakagawa, Tomomi Nagase, Keiko Kunitoki, Ryuta Kawashima
    27 Jan 2015 | 8:39 pm
    Abstract Recent investigations revealed mean diffusivity (MD) in gray matter and white matter areas is correlated with individual cognitive differences in healthy subjects and show unique properties and sensitivity that other neuroimaging tools donot have. In this study, we tested the hypothesis that the MD in the dopaminergic system is associated with individual differences in verbal creativity measured by divergent thinking (VCDT) and novelty seeking based on prior studies suggesting associations between these and dopaminergic functions. We examined this issue in a large sample of…
  • Reading in the brain of children and adults: A meta-analysis of 40 functional magnetic resonance imaging studies

    Anna Martin, Matthias Schurz, Martin Kronbichler, Fabio Richlan
    27 Jan 2015 | 8:39 pm
    Abstract We used quantitative, coordinate-based meta-analysis to objectively synthesize age-related commonalities and differences in brain activation patterns reported in 40 functional magnetic resonance imaging (fMRI) studies of reading in children and adults. Twenty fMRI studies with adults (age means: 23–34 years) were matched to 20 studies with children (age means: 7–12 years). The separate meta-analyses of these two sets showed a pattern of reading-related brain activation common to children and adults in left ventral occipito-temporal (OT), inferior frontal, and posterior parietal…

    Anneliese B. New, Donald A. Robin, Amy L. Parkinson, Claudia R. Eickhoff, Kathrin Reetz, Felix Hoffstaedter, Christian Mathys, Martin Sudmeyer, Christian Grefkes, Charles R. Larson, Loraine O. Ramig, Peter T. Fox, Simon B. Eickhoff
    27 Jan 2015 | 8:38 pm
    Abstract Over 90 percent of patients with Parkinson's disease experience speech-motor impairment, namely, hypokinetic dysarthria characterized by reduced pitch and loudness. Resting-state functional connectivity analysis of blood oxygen level-dependent functional magnetic resonance imaging is a useful measure of intrinsic neural functioning. We utilized resting-state functional connectivity modeling to analyze the intrinsic connectivity in patients with Parkinson's disease within a vocalization network defined by a previous meta-analysis of speech (Brown et al., 2009). Functional connectivity…
