Representation of binaural masking level difference in the inferior colliculus of the barn owl (tyto alba)
… Difference“ (BMLD). I recorded the activity of neurons in the central and external nuclei of the inferior colliculus (ICC and ICX, respectively) of the barn owl. These neurons are sensitive to a variation of the interaural delay. I tested three masking configurations: 1) the noise N and the tone …

Selektion, Charakterisierung und Entwicklung von neuronalen Subtypen des optischen Tektums des Huhns in vitro
… free conditions. Visual analysis allowed a first classification of the cells in different cell types. Immuncytochemical and electrophysiological evaluations enabled a further and more detailed assignment of tectal cells in vitro into different classes of cell types. The expression of different …

Möglichkeiten und Grenzen des Lichtfangs bei der ökologischen Bewertung von Nachtfalter-Artenspektren : ein Vergleich zwischen der räumlichen Verteilung von Nachtfalterimagines und der ihrer Präimaginalstadien
The object of this study lasting several years was to evaluate the suitability of light-trapping methods for studying the ecology of moths in general as well as questions concerning nature conservation in particular. It addresses the question as to whether and to what extent the habitats of adult …

Anatomical, morphometrical and biomechanical studies of barn owls' and pigeons' wings
Wings and feathers of barn owls (Tyto alba) were investigated with anatomical, morphometrical and biomechanical methods in order to specify noise reduction and noise suppressing structures evolved by the owl. Pigeons (Columba livia) with a similar body weight were taken as a reference species. Barn …

Bionische Rekonstruktion definierter neuronaler Netze aus Insekten und Vertebraten unter Verwendung elektromagnetischer Felder
… impossible to monitor all in- and outputs of a neuronal network and to provide stable and controlled conditions. Further, it is not possible to isolate a neuron´s activity from that of adjacent ones, because of the electronic coupling via the surrounding medium. Planar multi-electrode-arrays …
