Unleashing the Power of Aging Memories

Published on December 12, 2022

Imagine memories as seeds that need the right conditions and nurturing to grow. In our quest to enhance memory in older adults, we’ve developed new neurobiological models that could unlock the secret to reinforcing weak learning. Our frameworks propose that when weak memories are encountered alongside strong events, they have the potential to be strengthened and stabilized in long-term memory – a phenomenon known as the penumbra of memory. It’s like the penumbra, or shadow, surrounding a powerful source of light. Building on this concept, we welcome a thought-provoking response from Schomaker et al. who further explores our work. Discovering novel strategies for expanding the world of aging memories could have profound implications for improving cognitive function as we age. To learn more about our research and the exciting possibilities it holds, delve into the full article.

The significance of identifying easy and affordable ways to strengthen older adults’ memories cannot be overstated. As part of this endeavor, we recently synthesized neurobiological models of memory that could inform new ways to boost weak learning [1]. The core idea of these frameworks is that weakly encoded memories can become strengthened and stabilized in long-term memory when encountered in temporal proximity to a strong event – an effect we referred to as the penumbra of memory [1]. In an insightful reply to our Review, Schomaker et al.
