The Emotional Power of Memory
Memory and emotion are intimately entwined. Think of the most vivid memories you have with your loved one —chances are, they carry a strong emotional charge. Neuroscience shows that when we experience something deeply emotional, our brain tags it as important, strengthening the memory. “Memory is not a single process happening in one part of the brain,” says Dr. Ann Monis, PsyD. “It is a network of functions involving multiple regions, each responsible for encoding, storing & retrieving information. During times of emotional distress, such as grief, these processes can be altered in ways that affect how memories are experienced & recalled.” In her work, Monis describes “encoding” as the first step in memory formation, where sensory input is processed & transformed into something the brain can store. “Grief is able to strengthen some memories while weakening others,” she explains. “Strong emotions like sadness, fear, and love can make emotionally charged memories more vivid. This is why certain moments from the past, such as a final conversation with a loved one, may become sharper and more intense.”
This finding challenges the old assumption that strong emotions make us forget details; in fact, emotion can enhance memory for the little things, imprinting the entire scene more firmly
Scientists have long known that the amygdala, an almond-shaped hub of emotion in the brain, activates during emotional experiences and effectively tells the hippocampus (our memory center) “keep this one.” That’s one reason a joyful birthday party or the painful day of a funeral embeds itself so strongly in our long-term memory. Emotion enhances memory—it provides an energetic charge that the brain can capitalize on, to remember better. It’s a mechanism that likely served us in evolution (remembering dangers or rewards), but in grief it means our moments with a loved one—the laughter, the tears, the goodbyes—are stored with extra clarity and weight. This emotional amplification of memory can be a double-edged sword. When we lose someone, every memory of them is laden with feeling. A simple image of them smiling can trigger a cascade of emotion that makes it feel as though the event is happening now. And in a sense, the brain is indeed re-living it. Neuroscientists describe memory retrieval as reactivating the original pattern of brain activity from the experience itself. Remembering is literally a miniature reunion: At the neuronal level, remembering involves the retrieval of a past brain state into a present brain state. The same networks of neurons that fired when you and your mother baked pies years ago may fire again when the scent of cinnamon suddenly brings that moment flooding back. No wonder a vivid memory can bring tears or warmth to our eyes—for a moment, the brain makes it feel real once more. Importantly, not all memory triggers are visual or verbal. Our senses can ambush us with memories. Smell, especially, is known for unlocking emotional memories with peculiar power. A whiff of her perfume or the earthy smell of his tobacco can unleash a rush of recollection. Research confirms that odor-evoked memories tend to be more emotional and detailed than memories prompted by other cues
That’s because the brain’s olfactory pathways plug directly into emotion and memory circuits. A simple scent
