Ram Ram! Random Access, Random Memories: Becoming a late-in-life psychologist

Raju Korti
A few days back, I happened to read an article that has provided grist to my counselling mill. It was about how the brain “rescues” fragile memories and discards others. The study, published recently in Science Advances, explores how our memory system gives ordinary moments staying power when they are linked, before or after, to emotionally charged or rewarding experiences.

I am no cognitive psychologist or memory researcher, but I find this fascinating. My own vault of memories is cluttered not with grand moments but with stray, inconsequential ones. I can recall the pattern on a teacup from a forgotten afternoon or the exact sound of a ceiling fan from a childhood home, but not the details of a far more significant event. None of these recollections seem to fit neatly into the categories scientists describe. How does science explain such random retention? Perhaps even the brain does not always know why it keeps what it does.

The study argues that memory is not a passive recorder but an active decision-maker. It “rescues” fragile memories if they share a sensory or conceptual link with a meaningful event. My little research tells me that this phenomenon, called graded prioritization. means that the brain’s emotional circuitry can reach backward or forward in time to stabilise related experiences. For instance, an emotional high or shock can strengthen the memory of neutral moments that came just before or after it.In simpler terms, the brain saves stories, not snapshots. It chooses fragments that fit into a narrative it can later reconstruct. That to me explains why emotional significance, attention, and relevance to current goals weigh heavily in memory formation. The brain privileges what it finds useful for survival, learning, or identity building. Emotional events, especially those invoking stress or reward, activate the key regions that signal the brain to consolidate the experience into long-term storage.

Yet what intrigues me most is how arbitrary it still feels. Many of my most vivid memories have no emotional weight or logical purpose. They are sensory fragments. Smells, sounds, and fleeting visuals that seem detached from context. Maybe they once brushed against a meaningful experience, or maybe they were just efficiently encoded by chance. Science might call this selective capture, the brain’s way of economising energy by keeping only what fits its evolving model of the world. But that explanation feels, at best, partial.

This puzzle becomes even more interesting when we think about dreams. Some researchers believe that dreams are the brain’s nocturnal workshop, replaying and reorganising fragments of waking life to strengthen certain connections. Others suggest they are a by-product of random neural firing with no structured purpose. The boundary between dreams and memories often blurs. I have woken up unsure whether a vivid scene was a remembered event or a dream. Proof, perhaps, that both arise from the same creative, reconstructive process.

I understand that memory science is fundamentally an approximate science rather than a perfect one. It relies on observation, experimentation, and evolving theories to make sense of a fallible biological process. Even the most sophisticated brain imaging cannot fully decode how a fleeting sensory impression becomes an enduring recollection. Researchers are still uncovering how memories are encoded, stored, and retrieved, and how the emotional brain decides which ones to rescue and which to release into oblivion.

That uncertainty, in a way, makes the science even more beautiful. Memory, after all, is not about accuracy. It is about meaning. The fact that our minds sometimes cling to the trivial and discard the important may not be a flaw but a reflection of how deeply human, creative, and imperfect the process really is.
