Respiration-related membrane potential fluctuations were recorded in hypoglossal (XII) motoneurons and pre-Bötzinger complex (pre-BötC) interneurons in medullary slices from perinatal rats. Bath application of serotonin (5-HT) evoked a ketanserine-sensitive depolarization (approximately 11 mV) and tonic spike discharge in XII motoneurons, whereas pre-BötC(More)
In this paper we present a concept for integrating Multimedia-Enriched Learning Objects (MELOs) within a unifying technological framework for schools. First, we discuss the general role of objects for child development and learning. We then outline the framework architecture of the proposed Networked Environment for Multimedia Objects (NEMO). After-wards,(More)
An implication of 5-HT(2B) receptors in central nervous system has not yet been clearly elucidated. We studied the role of different 5-HT(2) receptor subtypes in the medullary breathing center, the pre-Bötzinger complex, and on hypoglossal motoneurons in rhythmically active transversal slice preparations of neonatal rats and mice. Local microinjection of(More)
In this paper we discuss the results of a mobile learning project a young art teacher in training conducted with fifth graders at a local higher secondary school in Germany. In contrast to stationary learning, effectively employed mobile learning technology provides students and teachers with the flexibility and the freedom to reach educational goals while(More)
This paper describes SpelLit, an application, which fosters literacy skills at elementary schools. For the development of our educational software, traditional concepts of learning have been adapted to fit the UniTable, a multi-touch tabletop system for educational purposes, aiming at students of all ages. Multi-touch technology lets users interact in easy(More)
By now " Moles " (Mobile Learning Exploration System) is a successfully used system for mobile learning in many school projects. Students can independently use Web Moles for PC (with limited rights, we call it Moles for Kids) to prepare excursions or mobile games. In the field, whether in the urban area, in a company, or in a biotope, etc., students can(More)
Dieses Paper widmet sich der interdisziplinären Betrachtung eines Kon-zepts zur Integration multimedialer, be-greifbarer Lernobjekte in vernetzte Lern-umgebungen. Mit Hilfe eines auf die Physis bezogenen Schalenmodells werden medienpädagogische,-theoretische,-soziologische und-systemtechnische Überle-gungen zusammengeführt.
Lamina I neurons of the spinal dorsal horn serve nociception both in mammals and in birds. The projection of these neurons to the brain is largely unknown in birds. Injections of retrogradely transported fluorescent tracers into various brainstem nuclei showed that these neurons, which are distributed throughout the spinal cord, heavily project to the(More)
