By Markus Lappe

Once we stroll, force a motor vehicle, or fly an aircraft, visible movement is used to regulate and advisor our move. Optic movement describes the attribute trend of visible movement that arises in those events. This e-book is the 1st to take an in-depth examine the neuronal processing concepts that underlie the brain's skill to investigate and use optic circulation for the regulate of self-motion. It does so in a number of species which use optic move in several behavioral contexts. The spectrum levels from flying bugs to birds, better mammals and guy. The contributions conceal physiological and behavioral reports in addition to computational versions. Neuronal Processing of Optic Flow offers an authoritative and entire evaluation of the present nation of analysis in this subject written by means of a bunch of authors who've made crucial contributions to shaping this box of study during the last ten years.

  • Provides the 1st particular evaluation of the research of complicated visible movement styles within the brain
  • Includes physiological, behavioral, and computational elements of optic circulate processing
  • Highlights similarities and transformations among diversified animal species and behavioral tasks
  • Covers human sufferers with visible movement deficits
  • Enhances the reader's realizing with many illustrations

Flüchten oder Bleiben? Rekonstruktion biographischer Verläufe und Ressourcen von Emigranten im Nationalsozialismus

Sylke Bartmann zeigt anhand der Rekonstruktion biographischer Verläufe von Emigranten unterschiedliche Umgehensweisen mit dem Nationalsozialismus und damit verbundene Repressalien und Bedrohungen auf. Der Fokus richtet sich dabei auf den Einzelnen als Akteur und Gestalter seines eigenen Lebens. Es wird die Frage beantwortet, inwieweit in den Prozessen der Biographisierung Ressourcen zum Ausdruck kommen, die das Leben im Nationalsozialismus (weiterhin) als zusammenhängend und sinnvoll erscheinen lassen - auch wenn dem einzelnen Menschen die Welt manchmal sinnentleert gegenüberzustehen scheint.

2c). In fact, errors are among the smallest reported for visual decomposition. The retinal flow fields for simulated translation + rotation and for circular heading are very similar, although they grow apart over time. This means that even if the flow field can be decomposed, the resulting ego rotation and heading constrain the eye’s path through space only partially: the locomotor path belongs to a family of straight and curved paths. Royden (1994) could explain the errors of her subjects by assuming that they perceived motion on a circular path (with the same angular path velocity and tangential velocity as the simulated eye rotation and eye translation) and that they indicated the location some 4 s ahead on that path.
