CAD in light optics and electron optics

In 1854 J. C. Maxwell devised his fish-eye lens a sphere with a radially diminishing refractive index [*1. The optical characteristics of this lens, which can produce aperfect image of an object, as the computer plot above suggests, are fairly easy to calculate analytically. This is not generally the case with optical elements of varying refractive index as used today for data transmission. The...

O9: The Impact of Neuroscience in Understanding Posttraumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a disorder which might occur in subjects after experiencing a traumatic life event. The underlying etiology of this disorder is still unknown but malfunction of the brain’s anxiety network is discussed. Therefore, neuroscience research might give new insights about the neurobiological mechanisms of PTSD. The talk will give a systematic overview abo...

DT-MRI Tractography and its Application in Cognitive Neuroscience

Recent advancement of MRI techniques and development of new methods of image analysis have allowed us to study large neural tracts within the human brain. This is based on the principle of diffusion tensor MRI that is similar to that of diffusion-weighted imaging but takes magnitude and direction of the diffusion of water into account. Using this technique we have been able to define large neur...
