Connectomes are comprehensive maps of the wiring within nervous systems, representing connections from the cellular and synaptic level (on the nanometer scale) to large-scale brain areas (on the centimeter scale). Network neuroscience focuses on modeling and analyzing these connectomes. While the primary goal of network neuroscience—understanding the principles of connectome organization and its impact on brain function—remains consistent across different scales, specific scientific questions often require examining particular spatial levels. For instance, exploring the relationship between clinical outcomes and connectome organization in humans currently requires analysis at the areal level. In my talk, I will present several ongoing research projects from my lab that span multiple scales of network neuroscience. These include nanoscale connectome analyses from model organisms such as C. elegans, Drosophila, and zebrafish, as well as large-scale functional MRI studies. I will conclude with a discussion of key open questions and challenges in the field, along with potential directions for advancing the discipline.
