“Memories, much like ripples on a pond, can appear distinct and vivid when fresh, but over time, their contours blur. Yet, we retain the ability to recall the essence of our memories, navigating our lives through the maps etched in our minds.”
Dr. Mark Brandon and a post-doctoral researcher in his group, J. Quinn Lee, published a commentary today in Neuron, entitled, “Time and experience are independent determinents of representational drift in CA1”. In this preview article, Lee and Brandon discuss two recent publications that delve into representational drift, the change in mental representations of space, over time.
Their commentary refers to:
- Active experience, not time, determines within-day representational drift in dorsal CA1
Neuron, Volume 111, Issue 15, 2 August 2023, Pages 2348-2356.e5
Dorgham Khatib, Aviv Ratzon, Mariell Sellevoll, Omri Barak, Genela Morris, Dori Derdikman
- Time and experience differentially affect distinct aspects of hippocampal representational drift
Neuron, Volume 111, Issue 15, 2 August 2023, Pages 2357-2366.e5
