NSF CREST D-MAP Center

The Georgia State University (GSU) center for dynamic multiscale and multimodal brain mapping across the lifespan [D-MAP] integrates investigators from 12 departments/programs and 5 colleges/schools across the university, focusing on highly interdisciplinary topics in areas from neuroscience to computer science to biomedical enterprise.

Together, we will address one of the greatest challenges we face today, uncovering the link between brain and behavior across the lifespan with the following subprojects.

Unimodal Brain Dynamics

We are developing methods to advance our understanding of time-varying brain connectivity (i.e. chronnectomics1) and the evolution of whole brain connectivity patterns over time (i.e., from milliseconds to seconds to minutes to years).

Multimodal Data Fusion

We are developing novel methods to lead the field in multivariate approaches to model linked changes in multi-modal measures and their trajectories over the lifespan. Key contributions we propose include 1) the incorporation of network subspaces (e.g. different subsets of modalities and networks show different behavior), 2) flexible approaches to identify links between data with mismatched dimensionality, e.g. brain function and structure, and 3) the development of multimodal models that leverage deep learning to capture more complex (potentially nonlinear) relationships. Initial emphasis will be on multimodal MRI and EEG/MEG data.

Predictive Neuroimaging

We are utilizing large open data repositories to develop predictive fingerprints of development and aging along multiple dimensions (e.g., age, individuality) including individuals from ages 2-80 (cross-sectional with embedded longitudinal cohorts within each age bracket). Anticipated contributions include 1) novel predictive multimodal models that evolve both within and among individuals, 2) advanced visualization approaches to enhance interpretability, and 3) development and use of neuroinformatics infrastructure for reproducible large N brain imaging data analysis of various populations.

The D-MAP CREST center represents a cutting-edge project that will build on synergistic efforts to provide important contributions to development and aging with applicability to many different aspects of neuroscience. D-MAP also represents a unique educational opportunity by combining a highly important and engaging research topic with a broad range of critical STEM skills including neuroscience, neuroimaging, data mining, analysis, machine learning, data visualization, neuroinformatics, and related technologies.
