CIMeC Colloquium Series

The Doctorate in Cognitive and Brain Science's Series of Colloquia

Announcing the 2023-2024 April Colloquium Speaker

ONLINE Thursday, April 11, 2024 4 p.m.

Quantifying Economy in Brain Networks

Professor Dani S. Bassett, J. Peter Skirkanich Professor, University of Pennsylvania

The human brain is organized as a network of interconnected components in the form of neural units, ensembles, areas, and regions. Across a range of spatial scales, that network is neither perfectly ordered nor perfectly random. Its heterogeneous organization supports complex activity dynamics while simultaneously constraining such dynamics. How does this constraint affect the cost of activity flow? In this talk, I will discuss the notion of network economy: the idea that the brain's network organization partially determines the cost of reaching a brain state, maintaining a brain state, and transitioning between brain states. I will draw ideas and examples from the field of network control theory, which provides a framework for calculating energy costs associated with network systems reaching, maintaining, and transitioning among brain states. The discussion will focus on basic principles and intuitions, and will point listeners to code repositories, primers, and methodological studies they might find useful in implementing the approach. I will close by broadening out to discuss how principles of network economy can inform our study of cognitive effort and executive function, as well as cognitive changes associated with neurodevelopment. 

The CIMeC Colloquia Series is an annual set of invited talks given by leading researchers in the mind/brain sciences, both from Italy and abroad, aimed principally at our PhD Students. Given the multi-disciplinary backgrounds of the CIMeC students and researchers, the Colloquia are aimed at a general scientific level rather than at a more specialized audience. Colloquia usually take place on the first Thursday of each month except August.
The 2023/24 Colloquium Committee: Elisa Pasquini, Matteo De Matola, Davide Mazzaccara. 
Academic Councilor: Dr. Moritz Wurm
