    Description / Table of Contents: Zusammenfassung. Die expansive Entwicklung minimal-invasiver Operationstechniken bedingt weltweit eine erheblich gesteigerte Nachfrage der operativen Fächer nach Lern-, Lehr- und Forschungsmöglichkeiten an den Körpern verstorbener Menschen in den anatomischen Universitätsinstituten. Die deutschen anatomischen Institute können dieser Nachfrage derzeit nur unzureichend genügen, da die räumliche und technische Infrastruktur für die Bearbeitung derartiger Fragestellungen zwar teilweise noch vorhanden ist, durch die sich wandelnden Forschungsschwerpunkte und die Forderung nach Erfüllung von Lehraufgaben ausschließlich in der Studentenausbildung aber keine freien Personal- und Finanzressourcen für die Lösung von Anwenderproblemen verfügbar sind. Um Planungsgrundlagen für den Aufwand zukünftiger klinisch-anatomischer Arbeiten für Qualitätssicherung, Aus-, Fort- und Weiterbildung bei modernen Interventionen zu schaffen, skizziert der Artikel aus eigener praktischer Erfahrung („ANAtoMIC“) abgeleitete wesentliche Voraussetzungen für derartige Projekte.
    Notes: Summary. The expansion of minimally invasive surgery worldwide provokes an intensive interest of all surgical disciplines in gaining possibilities for research, learning and teaching by operating on human corpses. Despite the fact that German anatomical institutes in general have the infrastructure to realise such clinical cooperations, at present they may offer such opportunities only to a restricted degree, since the concentration on student teaching and anatomic research limits the capacity of the staff for a commitment in this field of applied science. To provide a basis for future estimations of the efforts necessary to perform solo surgery on the human cadaver, especially with emphasis on research, quality control and teaching, this article reports on practical experiences with such a project named “ANAtoMIC”, identifying minimal conditions which have to be realised.

    Notes: Abstract It can be shown that the sequence of spontaneous movements in the active sleep of healthy neonates can be described as a Poisson process. This statistical model is the basis of the modelling of movement-related heart-rate reactions (MRHR) as a secondary process. Modelling these processes gives essential information about possible diagnostic parameters such as the mean frequency of classified movements in active sleep (AS), and characteristics of the course of MRHR. Optimisation of the reliability of interpreting power spectral parameters, analysis of longterm rhythms and designation of the physiological trends of neonatal heart rates can be attained if the results of time series analysis are compared with fitted simulations. Modifications and new techniques of data acquisition and processing are created by means of the computer model.

    Notes: Abstract On the basis of discrete Hilbert transform (DHT) realised by fast Fourier transform (FFT), a new strategy for automatic spike mapping is introduced. The further computation of the EEG time series after DHT results in the time series of the momentary power and the momentary frequency. Both are used for the solution of the main requirements of automatic spike mapping. The spike-mapping concept introduced meets the requirements of efficient automatic spike detection and also has an insensitivity with regard to EMG interference and transient signal components, a frequent cause of false positive detections. Additionally, there are advantages if the momentary power of the spike is mapped instead of the spike potential. the use of momentary power makes a combination of power spectral mapping and spikemapping strategies possible.

    Notes: Abstract From the basis of the fast Fourier transformation (FFT), the discrete Hilbert transformation (DHT) is used to compute the instantaneous respiration rate in neonates. This interval-related computation of respiration rate must be combined with a concept of adaptive filtration of the respiratory movements. This strategy is performed by adaptive recursive estimations of mean values with different adaptation constants. Additionally, a frequency band limitation is carried out on the basis of the peak characteristic of the power spectrum (respiratory movements). By means of the adaptive estimation of the variance of respiratory movements, an amplitude-time window is calculated to choose between epochs with breaths and apnoea.
