FIGGS Seminar - Sommersemester 17
We study the electrostatic properties of inhomogeneous nuclear matter which can be formed in the crusts of neutron stars or in supernova explosions. Such matter can be represented by Wigner–Seitz cells of different geometries (spherical, cylindrical, cartesian), which contain nuclei, free neutrons and electrons under the conditions of electrical neutrality. Using the Thomas–Fermi approximation, we have solved the Poisson equation for the electrostatic potential and calculated the corresponding electron density distributions in individual cells. The calculations are done for different shapes and sizes of the cells and different baryon densities. We have performed calculations for a simplified model of nuclei chosen as a Woods-Saxon distribution as well as for realistic nuclear structure calculations within the RMF model.
Transcranial magnetic stimulation (TMS) is a promising technique for non-invasive therapeutic treatment of psychiatric and neurological conditions. However, the same stimulation protocol can elicit opposing effects on excitability and plasticity in different subjects. The effects of TMS on neural circuits remain poorly understood, which hinders the development of maximally effective stimulation protocols. In this talk, I discuss basic principles of TMS and how computational modeling can help to understand the high variability of TMS effects.
The students who built the Neuroscience exhibition for the Night of Science and Hessentag will talk about their exhibits and how they came to be.
