    The work [11] deals with questions of first-order definability in algebraic function fields. In particular, it exhibits new cases in which the field of constant functions is definable, and it investigates the phenomenon of definable transcendental elements. We fix some of its proofs and make additional observations concerning definable closure in these fields.

  6. [deleted]Thomas Geyer, Florian Johannes Baumgartner, Hermann Josef Mueller & Stefan Pollmann (2012). Medial Temporal Lobe-Dependent Repetition Suppression and Enhancement Due to Implicit Vs. Explicit Processing of Individual Repeated Search Displays. Frontiers in Human Neuroscience 6.score: 300.0
    Using visual search, functional magnetic resonance imaging (fMRI) and patient studies have demonstrated that medial temporal lobe (MTL) structures differentiate repeated from novel displays – even when observers are unaware of display repetitions. This suggests a role for MTL in both explicit and, importantly, implicit learning of repeated sensory information (Greene et al., 2007). However, recent behavioral studies suggest, by examining visual search and recognition performance concurrently, that observers have explicit knowledge of at least some of the repeated displays ( (...) et al., 2010). The aim of the present fMRI study was thus to contribute new evidence regarding the contribution of MTL structures to explicit versus implicit learning in visual search. It was found that MTL activation was increased for explicit and, respectively, decreased for implicit relative to baseline displays. These activation differences were most pronounced in left anterior parahippocampal cortex, especially when observers were highly trained on the repeated displays. The data are taken to suggest that explicit and implicit memory processes are linked within MTL structures, but expressed via functionally separable mechanisms (repetition enhancement vs. -suppression). They further show that repetition effects in visual search would have to be investigated at the display level. (shrink)

    There is an ongoing debate as to whether singing helps left-hemispheric stroke patients recover from non-fluent aphasia through stimulation of the right hemisphere. According to recent work, it may not be singing itself that aids speech production in non-fluent aphasic patients, but rhythm and lyric type. However, the long-term effects of melody and rhythm on speech recovery are largely unknown. In the current experiment, we tested 15 patients with chronic non-fluent aphasia who underwent either singing therapy, rhythmic therapy, or standard (...)

    The year 2009 marked the 100th anniversary of the publication of the famous brain map of Korbinian Brodmann. Although a "classic" guide to microanatomical parcellation of the cerebral cortex, it is – from today's state-of-the-art neuroimaging perspective – problematic to use Brodmann's map as a structural guide to functional units in the cortex. In this article we discuss some of the reasons, especially the problematic compatibility of the "post-mortem world" of microstructural brain maps with the "in vivo world" of neuroimaging. (...)

  11. Christa Brüstle, Nadia Ghattas, Clemens Risi & Sabine Schouten (forthcoming). Zur Einleitung : Rhythmus im Prozess. Rhuthmos.score: 24.0
    Ce texte constitue l'introduction de C. Brüstle et al. (Hrsg.), Rhythmus im Prozess, Berlin, 2004. On le trouvera en ligne également ici. Il nous a été signalé par Andres Leon-Geyer que nous remercions de cette attention. Wenn von Rhythmus die Rede ist und wenn man nach einer Definition von Rhythmus fragt, so trifft man in der Regel auf Erklärungen wie die folgende : Rhythmus ist eine »unbedingt schematische Abfolge von betonten und nichtbetonten Zeitelementen, deren gesamte Einheit überschaubar (...) - (...)
