[institut] SCL Seminar: Bosiljka Tadic, Thursday, 10 October, 14:00

[Marija Mitrovic Dankulov]

Dear colleagues,

You are cordially invited to the SCL seminar of the Center for the Study 
of Complex Systems, which will be held on Thursday, 10 October 2019 at 
14:00 in the library reading room “Dr. Dragan Popović" of the Institute 
of Physics Belgrade. The talk entitled

Computational Modeling of the Brain & Hidden Structure of Human 
Connectomes

will be given by Prof. Dr. Bosiljka Tadić (Department of Theoretical 
Physics, Jozef Stefan Institute Ljubljana, Slovenia and Complexity 
Science Hub, Vienna, Austria). Abstract of the talk:

The modern science of the brain explores how the brain's anatomical 
parts and complex pathways between them govern human activity, 
psychology and behaviour. A  network that maps the organization of 
neuronal connections between brain regions is known as the human 
connectome. Currently, a large amount of experimental data has been 
collected within the Human Connectome Project (HCP) to enable different 
aspects of brain research. However,  the procedure to extract the 
network from the fMRI or another brain imaging methods, as well as the 
analysis of whole-brain networks, requires specific computational 
modelling approaches. In this seminar, we briefly review the necessary 
procedures preceding the construction of a brain network and describe 
some parameters that affect the outcome. Further, we discuss in detail 
[1] the consensus connectomes, that we generate for a specified set of 
parameters on the Budapest Conenctome Server [2] based on HCP data. By 
analyzing higher-order connections, we show how the consensus 
connectomes of female subjects systematically differ from the one for 
male subjects. Meanwhile, their standard graph-theoretic properties 
remain self-similar. These robust gender differences within the 
higher-order connectivity in human brain networks imply their different 
functional properties; whereas, the understanding of the origin and 
interpretation of these differences remain beyond the mathematical 
modelling framework.
