Cy Twombly. Bild, Text, Paratext

Die Bildwerke des US-amerikanischen Künstlers Cy Twombly (1928–2011) gelten als hermetisch und schwer zugänglich. Bleistiftgekritzel, Farbballungen, taumelnde Linien, einander überlagernde Farbschichten und Einschreibungen, geometrische Figuren, Zahlen, Zahlenreihen, Wörter, Zitatfragmente und rätselhafte Bildtitel stellen Forscher wie Betrachter vor ganz besondere Herausforderungen. Gemäß der interdisziplinär-transkulturellen Forschungsmethode des Internationalen Kollegs Morphomata an der Universität zu Köln versammelte im Juni 2012 ein Kongress neben Kunsthistorikern auch namhafte Fachleute aus den Bereichen Ägyptologie, Archäologie, Germanistik, Gräzistik, Anglistik, Japanologie und Romanistik, d.h. all jenen Fachgebieten und Kulturkreisen, die eine Inspirationsquelle für das OEuvre Cy Twomblys darstellten. Befragen diese den Bezug zwischen Werktitel, Werk und eingeschriebenen Zitaten, so legen führende Vertreter der Twomblyforschung den Fokus auf Bildsprache und Schriftbildlichkeit bei Cy Twombly. Durch umfassende Deutungen berühmter Einzelwerke und Werkgruppen in sämtlichen von Twombly angewandten künstlerischen Medien erschließt der Band in einem fächerübergreifenden Blick einen Zugang zur assoziativ-referentiellen Bildsprache Cy Twomblys

Cy Twombly. Image, Text, Paratext

The artworks of the US artist Cy Twombly (1928–2011) are considered to be hermetic and inaccessible. Pencil scribblings, explosions of paint, tumbling lines, overlapping layers of color, and inscriptions, geometrical figures, numerals, rows of numbers, words, fragments of quotations, and enigmatic work-titles present very special challenges to both researchers and viewers. In the interdisciplinary and transcultural research method of the Morphomata International Center for Advanced Studies at the University of Cologne, a conference was held in June 2012 that brought art historians together with renowned scholars of Egyptology, Archaeology, German, Greek, English, Japanese, and the Romance languages, i.e. all the fields and cultural spheres that were a source of inspiration for the œuvre of Cy Twombly. While these scholars inquire into the relation between title, work, and inscribed quotations, leading representatives of research on Twombly focus on the visual language and scriptural-imagistic quality of Cy Twombly’s work. Through comprehensive interpretations of famous single works and groups in all the artistic media employed by Twombly, the volume’s cross-disciplinary view opens up a route into the associative-referential visual language of Cy Twombly

Neurointerfaces, mental imagery and sensory translation in art and science in the digital age

The chapter focuses on the issue of transmedial and sensory exchange in the context of digital culture and biometric technology. It analyzes critically the epistemic claims behind the various brain-scanning technologies, focusing on the status of the inner images that underlie cognitive activity. Multimedia performances and artistic experiments designed in collaboration with neuroscientists open up new dimensions in the discussion of translation between different sensory modalities, as well as translation between human perceptive apparatus and computational systems. Engaging the methodologies of contemporary image science and critical neuroscience, the paper shows how artistic scenarios help to both localize and expand our understanding of mental imagery and to offer an alternative to the existing correlations-based approach.FGW – Publications without University Leiden contrac

The sense of smell, its signalling pathways, and the dichotomy of cilia and microvilli in olfactory sensory cells

Smell is often regarded as an ancillary perception in primates, who seem so dominated by their sense of vision. In this paper, we will portray some aspects of the significance of olfaction to human life and speculate on what evolutionary factors contribute to keeping it alive. We then outline the functional architecture of olfactory sensory neurons and their signal transduction pathways, which are the primary detectors that render olfactory perception possible. Throughout the phylogenetic tree, olfactory neurons, at their apical tip, are either decorated with cilia or with microvilli. The significance of this dichotomy is unknown. It is generally assumed that mammalian olfactory neurons are of the ciliary type only. The existance of so-called olfactory microvillar cells in mammals, however, is well documented, but their nature remains unclear and their function orphaned. This paper discusses the possibility, that in the main olfactory epithelium of mammals ciliated and microvillar sensory cells exist concurrently. We review evidence related to this hypothesis and ask, what function olfactory microvillar cells might have and what signalling mechanisms they use
