Title: Networks in neuroscience: Functional and structural brain connectivity
Authors: Wendy Meiring - University of California Santa Barbara (United States) [presenting]
Abstract: Two applications of networks are reviewed when estimating functional and structural brain connectivity. Part 1: Resting-state functional brain connectivity quantifies the similarity in neuronal activity (firing) across brain regions/voxels within brain regions over time. Each brain region consists of voxels at which dynamic signals are acquired via neuroimaging measurements, such as blood-oxygen-level-dependent (BOLD) signals in functional magnetic resonance imaging (fMRI). Pearson correlations and similar metrics are frequently adopted by neuroscientists to estimate inter-regional functional connectivity, often after averaging of signals across voxels within each region; however, careful attention needs to be paid to account for inter- and intra-regional spatiotemporal noise on these estimates. Part 2: Network concepts used in structural (anatomical) brain connectivity estimation are reviewed based on structural MRI scans.
