Agency (Bengaluru): Our memories shape our identities, guide our decisions, and connect us to the world around us. Yet, for many people, the prospect of forgetting important information, such as a crucial meeting or the name of a familiar face, can be a source of anxiety and self-doubt. In her book, “Remember, the Science of Memory and the Art of Forgetting,” neuroscientist and author Lisa Genova explores the intricacies of human memory, emphasizing that forgetting is a normal part of the human experience and that we can take steps to nurture and support our brain’s remarkable ability to remember.
One of the key takeaways from Genova’s work is that attention is the foundation of memory formation. Our brains are constantly bombarded with sensory information, but we can only encode and store a fraction of these experiences as memories. By consciously directing our attention to the things we want to remember, whether it’s the location of our glasses or the details of a conversation, we increase the likelihood that this information will be successfully encoded and retrieved later.
However, even when we do pay attention, our memories are not infallible. Stress, in particular, can have a profound impact on our ability to form and recall memories. When we experience acute stress, our bodies release hormones like adrenaline and cortisol, which prepare us to fight or flee from perceived threats. This response is adaptive in the short term, but when stress becomes chronic, it can take a toll on our brain’s memory systems. As Genova explains, chronic stress can lead to the shrinkage of the hippocampus, a brain region that plays a crucial role in forming and storing conscious memories. It can also inhibit neurogenesis, the birth of new neurons, which is essential for maintaining a healthy and adaptable brain.
Fortunately, there are steps we can take to combat the effects of stress on our memory. Practices like yoga, meditation, and mindfulness have been shown to reduce stress levels and even restore the size of the hippocampus in people who have experienced chronic stress. Genova offers a simple nine-second meditation that involves breathing slowly in and out through the nose, which can help regulate cortisol levels and promote a sense of calm and safety.
Sleep is another essential factor in memory formation and consolidation. During sleep, our brains are hard at work processing and integrating the information we’ve learned throughout the day. If we don’t get enough sleep, our ability to form new memories and retrieve old ones can be compromised. This is because sleep deprivation can impair the function of the frontal lobe, which is responsible for attention and executive function, as well as the hippocampus, which is involved in memory consolidation.
When it comes to remembering specific pieces of information, like names or dates, Genova suggests that we can increase our chances of success by creating multiple associations and pathways in our brains. For example, if we’re trying to remember someone’s name, we can create a visual or semantic association, like picturing them wearing a baker’s apron if their name is Baker. We can also benefit from repetition and rehearsal, whether it’s by writing down the information we want to remember or by testing ourselves on it later.
Genova also challenges the notion that relying on external aids, like to-do lists or digital calendars, is a sign of weakness or impending cognitive decline. In fact, she argues that offloading some of our memory tasks to external tools can free up our mental resources for other important tasks, like problem-solving and creativity. She points out that even highly skilled professionals, like airline pilots, rely on checklists and protocols to ensure that critical tasks are completed safely and efficiently.
Perhaps most importantly, Genova emphasizes that forgetting is a normal and inevitable part of the human experience. Our brains are not designed to store every piece of information we encounter, and the occasional memory lapse, like having a word stuck on the tip of our tongue, is not a sign of impending dementia or cognitive decline. By embracing the imperfections of our memories and taking steps to support our brain’s natural ability to learn and remember, we can cultivate a more positive and resilient relationship with our own minds.
In a world that often demands perfection and constant productivity, it can be tempting to view our memories as yet another area in which we must excel. However, as Genova’s work reminds us, our memories are not meant to be flawless repositories of information, but rather dynamic and adaptable systems that allow us to navigate the complexities of our lives. By paying attention to the things that matter, taking steps to manage stress and prioritize sleep, and creating rich associations and pathways in our brains, we can support our memory’s natural abilities and embrace the inevitable forgetting that comes with being human.
At the same time, it’s important to recognize that significant and persistent changes in memory, like difficulty performing familiar tasks or getting lost in familiar places, can be signs of more serious cognitive issues and should be evaluated by a healthcare professional. By staying attuned to our own cognitive health and seeking help when needed, we can ensure that we’re taking the best possible care of our remarkable and complex brains.
Ultimately, the science of memory and the art of forgetting are not about achieving perfect recall or avoiding all instances of forgetfulness. Rather, they are about cultivating a deeper understanding and appreciation of the incredible capabilities and natural limitations of our own minds. By embracing the imperfections of our memories and taking steps to support our brain’s resilience and adaptability, we can lead more fulfilling and cognitively healthy lives, even in the face of the occasional forgotten name or misplaced set of keys.
