The human brain undergoes dramatic shifts in cellular composition, activity, and connectivity across the lifespan. This talk will showcase new research on network dynamics supporting memory and control processes in children, young adults, and older adults. A common theme is the role of rhythmic theta networks underlying cognitive performance. Theta rhythms mature from childhood into young adulthood, mirroring changes brain structure, and strengthened theta networks explain developmental improvements in memory. In young adults, theta rhythms support multiple cognitive processes associated with different brain networks. In older adults, manipulating theta networks improves cognitive performance and intervention efficacy reflects individual brain structure. Understanding lifespan neurophysiology carries broad impact for early detection of dysfunction and the design of therapeutic interventions.
