Reagh’s research is motivated by two main questions: (1) How does the human brain parse, store, and retrieve dynamic experiences, like those we encounter in our everyday lives? (2) How do these processes change in healthy aging and with age-related pathology, such as Alzheimer’s disease? To answer these questions, the Cognitive Neuroscience of Memory and Aging (CNMA) Lab uses realistic stimuli (such as movies and stories) in combination with behavioral experiments and neuroimaging techniques. Recent studies in the lab focus on distinct contributions of different brain networks to building memories for events, and selective vulnerabilities of these networks in neurocognitive aging.
