  • Olken, Benjamin A.; Pande, Rohini (Annual Reviews, 2012-04)
    Recent years have seen a remarkable expansion in economists' ability to measure corruption. This in turn has led to a new generation of well-identified, microeconomic studies. We review the evidence on corruption in ...
  • Overath, Tobias; Zarate, Jean Mary; Poeppel, David; McDermott, Josh (Nature Publishing Group, 2015-05)
    Speech contains temporal structure that the brain must analyze to enable linguistic processing. To investigate the neural basis of this analysis, we used sound quilts, stimuli constructed by shuffling segments of a natural ...
  • Miller, Earl K.; Buschman, Timothy J. (Elsevier, 2012-12)
    How are some thoughts favored over others? A wealth of data at the level of single neurons has yielded candidate brain areas and mechanisms for our best-understood model: visual attention. Recent work has naturally evolved ...
  • Kumar, S.; Black, S. J.; Hultman, R.; Szabo, S. T.; DeMaio, Kristine D.; Du, J.; Katz, B. M.; Covington III, Herbert E.; Dzirasa, K.; Feng, Guoping (Society for Neuroscience, 2013-01)
    Transcranial magnetic stimulation and deep brain stimulation have emerged as therapeutic modalities for treatment refractory depression; however, little remains known regarding the circuitry that mediates the therapeutic ...
  • Kiyomitsu, Tomomi; Cheeseman, Iain McPherson (Elsevier, 2013-07)
    Mitotic spindle position defines the cell-cleavage site during cytokinesis. However, the mechanisms that control spindle positioning to generate equal-sized daughter cells remain poorly understood. Here, we demonstrate ...
  • Shi, Feng; Yap, Pew-Thian; Fan, Yong; Cheng, Jie-Zhi; Wald, Lawrence; Gerig, Guido; Lin, Weili; Shen, Dinggang (Institute of Electrical and Electronics Engineers, 2009-08)
    The acquisition of high quality MR images of neonatal brains is largely hampered by their characteristically small head size and low tissue contrast. As a result, subsequent image processing and analysis, especially for ...
  • Rajendran, Niranjini; Busa, Evelina; Augustinack, Jean; Mohlberg, Hartmut; Amunts, Katrin; Zilles, Karl; Fischl, Bruce; Hinds, Oliver; Yeo, B. T. Thomas (Oxford University Press (OUP), 2007-12)
    The human cerebral cortex is made up of a mosaic of structural areas, frequently referred to as Brodmann areas (BAs). Despite the widespread use of cortical folding patterns to perform ad hoc estimations of the locations ...
  • Rockland, Kathleen; DeFelipe, Javier (Frontiers Research Foundation, 2012-05)
    In the cerebellum and basal ganglia, projection neurons are GABAergic; but in the cerebral cortex, there has been a historically strong dichotomy between glutamatergic projection neurons and GABAergic local circuit neurons. ...
  • Supp, Gernot G.; Siegel, Markus; Hipp, Joerg F.; Engel, Andreas K. (Elsevier, 2011-11)
    Intrinsic cortical dynamics modulates the processing of sensory information and therefore may be critical for conscious perception [1, 2 and 3]. We tested this hypothesis by electroencephalographic recording of ongoing and ...
  • Siegel, Markus; Buschman, Timothy J.; Miller, Earl K. (American Association for the Advancement of Science (AAAS), 2015-06)
    During flexible behavior, multiple brain regions encode sensory inputs, the current task, and choices. It remains unclear how these signals evolve. We simultaneously recorded neuronal activity from six cortical regions ...
  • Khuc Trong, Philipp; Dunkel, Joern; Doerflinger, Helene; St. Johnston, Daniel; Goldstein, Raymond E. (eLife Sciences Publications, Ltd., 2015-09)
    Many cells contain non-centrosomal arrays of microtubules (MTs), but the assembly, organisation and function of these arrays are poorly understood. We present the first theoretical model for the non-centrosomal MT cytoskeleton ...
  • Goldberg, Jesse H.; Fee, Michale S. (Nature Publishing Group, 2012-02)
    The pallido-recipient thalamus transmits information from the basal ganglia to the cortex and is critical for motor initiation and learning. Thalamic activity is strongly inhibited by pallidal inputs from the basal ganglia, ...
  • Siegel, Markus; Engel, Andreas K.; Donner, Tobias H. (Frontiers Media S.A., 2011-02)
    Goal-directed behavior requires the flexible transformation of sensory evidence about our environment into motor actions. Studies of perceptual decision-making have shown that this transformation is distributed across ...
  • Norman-Haignere, Samuel Victor; Kanwisher, Nancy; McDermott, Josh (Society for Neuroscience, 2013-12)
    Pitch is a defining perceptual property of many real-world sounds, including music and speech. Classically, theories of pitch perception have differentiated between temporal and spectral cues. These cues are rendered ...
  • Dickerson, Bradford C.; Bakkour, Akram; Salat, David H.; Feczko, Eric; Pacheco, Jenni; Greve, Douglas N.; Grodstein, Fran; Wright, Christopher I.; Blacker, Deborah; Rosas, H. Diana; Sperling, Reisa A.; Atri, Alireza; Growdon, John H.; Hyman, Bradley T.; Morris, John C.; Fischl, Bruce; Buckner, Randy L. (Oxford University Press, 2008-07)
    Alzheimer's disease (AD) is associated with neurodegeneration in vulnerable limbic and heteromodal regions of the cerebral cortex, detectable in vivo using magnetic resonance imaging. It is not clear whether abnormalities ...
  • Rockland, Kathleen; DeFelipe, Javier (Frontiers Research Foundation, 2012-01)
    The tracts within the subcortical white matter and corpus callosum provide an anatomical connectivity that is essential for normal cognitive functioning. These structures are predominantly made up of axons that are myelinated ...
  • Pennartz, Cyriel M. A.; Berke, Joshua D.; Ito, Rutsuko; Lansink, Carien S.; van der Meer, Matthijs; Redish, A. David; Voorn, Pieter; Graybiel, Ann M.; Smith, Kyle S. (Society for Neuroscience, 2009-10)
    This mini-symposium aims to integrate recent insights from anatomy, behavior, and neurophysiology, highlighting the anatomical organization, behavioral significance, and information-processing mechanisms of corticostriatal ...
  • Geiser, Eveline; Gabrieli, John D. E. (Society for Neuroscience, 2012-05)
    The temporal context of an acoustic signal can greatly influence its perception. The present study investigated the neural correlates underlying perceptual facilitation by regular temporal contexts in humans. Participants ...
  • Bagchi, Arjun; Detournay, Stephane; Grumiller, Daniel; Simon, Joan (American Physical Society, 2013-10)
    Flat space cosmology spacetimes are exact time-dependent solutions of three-dimensional gravity theories, such as Einstein gravity or topologically massive gravity. We exhibit a novel kind of phase transition between these ...
  • Chernoff, David F.; Bloomfield, Jolyon (American Physical Society, 2014-06)
    Cosmic superstring loops within the galaxy microlens background point sources lying close to the observer-string line of sight. For suitable alignments, multiple paths coexist and the (achromatic) flux enhancement is a ...
