Brain structure-function relationship across mammalian evolution: Perspectives from spectral and information theory

15 January 2024

Colloquium by Dr. Alessandra Griffa, Leenaards Memory Center, Lausanne University Hospital and University of Lausanne

Abstract:
Understanding how brain function can be supported by patterns of neural signaling throughout its structural backbone is one of the enduring challenges of network and cognitive neuroscience. This question can be approached from different angles. From a data-driven perspective, graph signal processing allows to decompose signals living at the nodes of a network and study their characteristics as a function of the network architecture. From a model-based perspective, brain communication models explore network-level strategies of information transmission throughout the brain. Here, information theory can bring in new tools to probe communication models and assess their coherence with empirical data. In this talk, I will cover both perspectives and show how the brain structure-function relationship changes across subjects and species. Our results provide evidence that these brain communication changes are tied to the evolution of mammalian brain networks.
