Brain Connectomics: Opportunities for High-Performance Computing (Final Report)
- Lawrence Livermore National Laboratory (LLNL), Livermore, CA (United States)
The human brain is estimated to contain approximately 100 trillion neural connections. This complex map of connectivity (human connectome) underlies cognitive processes and informs disease states, but until recently, studying the human connectome has been hampered by the difficulty of collecting and processing suitable data for analysis. In this context, an initiative denominated The Human Connectome Project (HCP) was created to acquire and collect the largest, most cohesive set of brain data to accelerate neuroscience research. Recently the HCP released a magnetic resonance (MR) dataset of brain imagery with unprecedented scale and organization, together with high quality spatial and temporal resolution; however, fully taking advantage of this high-resolution brain imagery to estimate neurological connectivity networks requires high-performance computing (HPC). In this project, we explored the feasibility of using HPC resources at Lawrence Livermore to effectively estimate brain connectivity networks from this large set of imagery. Specifically, we addressed one of the main current challenges in brain connectomics, which is to advance the computation of individual structural and functional connectomes.
