How do we remember smells for so long if olfactory sensory neurons only survive for about 60 days?

摘要

Donald A. Wilson, a zoology professor at the University of Oklahoma and co-author of Learn-ing to Smell (Johns Hopkins University Press, 2006), replies: We recognize an old scent, despite having re-placed at least a subset of the olfactory sensory neurons that first interacted with that odor, because the overall pattern of activity within the olfactory system remains relatively constant over time.
