Title: Temporal Variability of Brain-Behavior Relationships in Functional Connectivity.
Session: Oral Session
Speaker: Sarah Cutts
Abstract: Most work analyzing functional connectivity (FC) has focused on collecting more data through longer scans to improve reliability and generalizability of brain-behavior relationships and predictions. However, recent developments in time-varying FC suggest that fluctuations within a scan reveal unique relationships with behavior and individual variability not seen from full FC. It remains unclear whether there are moments in time when brain-behavior relationships are more strongly expressed than in full FC and if these moments differ across distinct behaviors. We perform optimizations across 58 different behaviors to identify time points that optimally express brain-behavior relationships.
