Where: NIL Large Conference Room 2311 (Medical Campus, 4525 Scott Ave.)

Abstract:  I will highlight recent efforts from my lab that have incorporated tools from network science to describe differences in brain network organization over the human adult lifespan. To achieve this goal, we have been examining multiple large data sets that include participants sampled across a wide age range of adulthood (20-89yrs). The descriptions of network organization will include our recent work on using resting-state correlations to parcellate the brain into distinct cortical areas, revealing both the similarities and differences in the location of functional brain areas across age. The functional areas are treated as nodes to model large-scale network properties of the brain. Brain network organization differs with increasing age, demonstrating decreased segregation of brain systems. Importantly, individual differences in network organization relate to differences in both cognitive ability and brain function, providing evidence that the brain’s network organization relates to differences in behavior and information processing observed in healthy aging.
