This 13-minute talk by Andrea Marino from the Applied Algebraic Topology Network introduces DyNeuSR, a tool for visualizing complex brain dynamics captured through functional Magnetic Resonance Imaging (fMRI). Discover how the Mapper algorithm transforms intricate temporal brain activity patterns into an interpretable graph structure, where nodes represent recurring brain states and connections show similarities between these states. Learn how DyNeuSR enhances this approach by integrating neuroscientific annotations with topological data analysis, creating an intuitive framework for exploring and understanding brain activity. The presentation covers the challenges of relating brain dynamics to function in modern neuroscience and demonstrates how topological methods can provide valuable insights. Created by C. Geniesse, O. Sporns, G. Petri, and M. Saggar, this tool is available on GitHub with working examples and installation instructions for researchers interested in implementing these visualization techniques in their own neuroscience work.
