Brain Dynamics and its Control: Computational Approaches
2:00PM, Zoom - contact mbichuch@buffalo.edu for link
The brain is a complex nonlinear system, and it is challenging to understand its dynamics. In addition, the brain possesses plasticity, which frequently results in a temporary improvement followed by a decline after brain disease treatment. We have been developing computational modeling techniques for brain dynamics analysis to address these issues. In this presentation, several computational modeling studies utilizing electrophysiology data, such as calcium imaging and voltage-sensitive dye imaging data, along with energy landscape analysis studies using fMRI data, will be discussed. I will conclude by discussing our recent computational framework for brain control, which can account for both brain dynamics and plasticity.

Automorphisms of the fine curve graph
4:00PM, 122 Mathematics BuildingThe fine curve graph of a surface was introduced by Bowden, Hensel and Webb. It is defined as the simplicial complex where vertices are essential simple closed curves in the surface and the edges are pairs of disjoint curves. We show that the group of automorphisms of the fine curve graph is isomorphic to the group of homeomorphisms of the surface, which shows that the fine curve graph is a combinatorial tool for studying the group of homeomorphisms of a surface. This work is joint with Adele Long, Dan Margalit, Anna Pham, and Claudia Yao.
