From calcium diffusion in microdomains of neurons to human behavior

by Armin Biess
from Weizmann Institute of Science, Rehovot, Israel

Contact person: J. Michael Herrmann


Seminarraum Haus 2, 4. Stock (Bunsenstr.)


In this talk I will provide an overview of my current research interests that span from the modeling of microstructures in neurons to the description of human arm movements. I will first present recent results describing the time course of diffusing molecules in dendritic spines, the sites where most of the excitatory synapses in neurons occur. Through a combination of theory, molecular simulations and experiments I will discuss the influence of geometry on the regulation of diffusing molecules, such as calcium, across the spine neck. Second, I will present a model for the estimation of diffusion in crowded (heterogeneous) dendrites. Finally, I will briefly describe modeling approaches to 3D human arm movements using geometric concepts common in physics.
