In their new publication in The Journal of Neuroscience, “Feedback-based learning in aging: Contributions and trajectories of change in striatal and hippocampal systems“, Dr. Lighthall and her co-authors present novel findings indicating that hippocampal circuits supporting learning and memory decline more than striatal circuits in healthy aging. Their results further suggest that declines in hippocampal learning signals may be an important predictor of deficits in learning-dependent economic decisions among older adults. This project was conducted in collaboration with Dr. John Pearson (Assistant Professor of Biostatistics and Bioinformatics), Dr. Scott Huettel (Professor of Psychology and Neuroscience), and Dr. Roberto Cabeza (Professor of Psychology and Neuroscience) from the Center for Cognitive Neuroscience at Duke University.
