Overview

In her insightful talk, Lisa Genova sheds light on the nature of memory and why we often forget things. Forgetfulness is a common human trait, but it doesn't imply failure. She emphasizes that attention is the cornerstone of memory formation. Without focus, memories don't form as the brain never registers the information. Chronic stress, on the other hand, has a detrimental impact on memory, specifically on the hippocampus, which is crucial for forming long-term memories.

Lisa provides actionable strategies to improve memory. Stress-busters like meditation and exercises replenish the hippocampus, restoring memory capacities. Sleep is not just rest time—it's when the brain actively works on consolidating memories. Interestingly, caffeine, when not hampering sleep, heightens attention and assists memory. To remember names better, one should create mental associations, making retrieval easier. Repetition through writing or self-testing further strengthens memory.

Interestingly, she dispels myths around memory aids: digital tools like Google enhance rather than weaken our memory capability. Forgetting, she concludes, is a natural part of brain function and integral to being human. Embracing memory's imperfections, while employing techniques to foster its resilience, leads to a healthier relationship with our cognitive abilities.

Chapters

• 00:00 - 00:30: Introduction to Memory Worries The chapter 'Introduction to Memory Worries' addresses common concerns about forgetfulness, such as missing appointments or not recalling names of actors. It discusses how these lapses are often perceived negatively as signs of mental weakness or poor character, but suggests that such forgetfulness is a normal part of life.
• 00:30 - 01:00: Understanding Normal Forgetting The chapter explores the concept of normal forgetting, reassuring readers that forgetting is a natural and human process. It emphasizes the importance of maintaining a healthy relationship with memory and not fearing the inevitable aspect of forgetting. The chapter is based on insights from Lisa Genova, a neuroscientist and the author of 'Remember: The Science of Memory and the Art of Forgetting.'
• 01:00 - 01:30: Attention: Key to Memory Formation This chapter discusses the role of attention in reinforcing and forming long-lasting memories. It emphasizes that giving an object or information proper attention is crucial to creating a memory that can endure over time. The chapter uses the example of putting down glasses without paying attention as a scenario where memory is likely to fail.
• 01:30 - 02:30: Impact of Chronic Stress on Memory The chapter discusses how chronic stress impacts memory formation and retention. It explains that when someone fails to pay attention, they won't form memories accurately. Stress hormones are prioritized for immediate survival responses rather than memory processing, thus impairing the ability to remember or focus. Stress is naturally designed to be a short-term reaction, and chronic stress disrupts this process, leading to memory issues.
• 02:30 - 03:30: Combatting Stress with Mindfulness The chapter titled "Combatting Stress with Mindfulness" discusses the impact of chronic and unrelenting stress on the brain and body. It explains that under such stress, the body continually releases adrenaline and cortisol, which is detrimental to memory. This stress can lead to the shrinking of the hippocampus, a critical area of the brain associated with essential memory functions.
• 03:30 - 04:30: Meditation for Memory The chapter emphasizes the negative impact of stress on memory formation and neurogenesis, the process of creating new neurons. It highlights the importance of activities such as yoga, meditation, mindfulness, and exercise as effective methods to counter stress and promote mental health.
• 04:30 - 05:30: Importance of Sleep for Memory This chapter discusses the relationship between sleep and memory, highlighting the importance of restorative practices like meditation to manage stress and maintain the health of the hippocampus. The hippocampus is essential for memory, and chronic stress can affect its size and function. The chapter suggests a simple nine-second meditation technique to help balance cortisol levels and support hippocampal health, ultimately aiding memory retention.
• 05:30 - 06:00: Role of Caffeine in Memory In this chapter titled 'Role of Caffeine in Memory,' the discussion starts by focusing on the significance of breathing techniques to manage stress. It explains that breathing in through the nose, holding, and releasing can signal the brain and body that they are safe, thereby reducing stress responses. The chapter hints at the importance of getting enough sleep but doesn't directly delve into the role of caffeine yet in this introductory part. The detailed exploration of how caffeine might affect memory is anticipated to follow this initial set-up, connecting stress management and sleep to caffeine's effects.
• 06:00 - 07:30: Memory Techniques: Associations and Repetition The chapter discusses the importance of sleep in relation to memory and brain function. Sleep is portrayed not as a period of inactivity but as a time when the brain is actively working on essential processes related to memory.
• 07:30 - 08:30: Using Writing to Strengthen Memories The chapter discusses the role of attention and sleep in memory formation. It emphasizes how the hippocampus helps consolidate information into lasting memories during sleep. It also highlights the consequence of insufficient sleep, which could hinder the hippocampus's ability to form new memories effectively.
• 08:30 - 09:30: The Role of Self-Testing in Memory This chapter explores how memory is influenced by certain activities and habits. It discusses how memories from recent events or learnings, like from the previous day, might not be fully formed immediately. The chapter highlights caffeine as beneficial for memory, as it enhances attention, which indirectly boosts memory. Additionally, sleep is emphasized as crucial for the formation of memories.
• 09:30 - 10:30: Understanding Memory Glitches: Tip of the Tongue The chapter discusses the effects of caffeine on memory, emphasizing that while caffeine can enhance memory, it should not disrupt sleep. It further explores how human brains struggle with remembering names since they are abstract concepts stored in isolated neural pathways, likened to 'neurological cul-de-sacs.' To overcome this challenge, it suggests creating more associations with the person's name to improve memorability.
• 10:30 - 11:00: Conclusion: Embrace Your Memory's Capabilities The chapter discusses a psychological phenomenon known as the 'Baker-Baker Paradox,' illustrating how people have a harder time remembering abstract information like names but can more easily recall concrete images or associations related to that information. For instance, remembering the name 'Mr. Baker' is challenging, whereas recalling someone referred to as a 'baker' invokes vivid imagery of aprons, flour, and personal experiences with bakeries. This exemplifies the broader theme of the chapter: embracing and leveraging the associative nature of human memory for better recall.

9 tactics to build a stronger mind | Lisa Genova Transcription

• 00:00 - 00:30 - People are worried about their memory. If you're forgetting to show up for your four o'clock meeting, or you forgot the actor who played Tony Soprano in the HBO series 'The Sopranos.' "Can't remember that guy's name, what is it?" A lot of us tend to blame ourselves. This absent-mindedness is a sign of mental weakness, or a failing memory, or a lack of character, but 99% of forgetting that happens to all of us,
• 00:30 - 01:00 is normal. So there are things that we can do to be less afraid, less panicked, to have a better relationship with our memory today- because forgetting is a normal part of being human. My name is Lisa Genova. I am an author and neuroscientist. The name of my book is "Remember: The Science of Memory and the Art of Forgetting."
• 01:00 - 01:30 So how do we reinforce our memories? How do we make our memories stronger, resilient to time, so that we can recall them decades later? The first essential ingredient in creating a memory that's going to last longer than this present moment is attention. If I put my glasses down and don't give it a moment's attention
• 01:30 - 02:00 to notice where I've put this, I can't remember where they are because I never formed that memory to begin with. Your brain will never remember what you don't pay attention to. Chronic stress is really bad for our memory. Stress hormones mobilize your brain and body to respond, to fight, to flee, to react quickly- not to think. Stress is meant to be an acute, quick,
• 02:00 - 02:30 on and off phenomenon. So what happens in your brain and body if you're exposed to chronic, unrelenting stress, and how does that affect your memory? Under chronic stress, your body will just keep dumping adrenaline and cortisol, and it can't shut off. This is bad for memory. You are actually shrinking your hippocampus- the part of your brain that's essential
• 02:30 - 03:00 for forming consciously-held memories is going to be smaller. You'll be inhibiting 'neurogenesis,' the birth of new neurons. The very good news about all of this, because I've probably just scared everyone, is that there are things that we can do to combat stress. This is where things like yoga, meditation, mindfulness, and exercise come into play. All of these have been shown
• 03:00 - 03:30 to restore the size of people's hippocampus who have been chronically stressed. A quick word on meditation: A lot of people are intimidated by meditation. They sort of know that this is probably good for them in lots of ways, but maybe don't know how to do it. Here's a nine-second meditation to help restore your cortisol levels, and to help save your hippocampus and your ability to remember. Close your eyes if you can.
• 03:30 - 04:00 Breathe in through your nose to the count of four. Hold it for a second, and then breathe out through your nose to the count of four. And notice how you feel. Here's what's going on: Stress response causes you to breathe like this- By breathing slowly in and out through your nose, you are telling your brain and body that you are safe. We also wanna get enough sleep.
• 04:00 - 04:30 Sleep is not a state of doing nothing where you're unconscious and it's a waste of time. You're very biologically busy while you sleep, and there are a number of super-important things that are going on in your brain with respect to memory. For example, if I got a horrible night's sleep last night, I'm gonna wake up today and my frontal lobe is gonna have a hard time dragging itself to its day job-
• 04:30 - 05:00 and one of its most important jobs is paying attention. And if I can't pay attention to what's going on today, what am I not gonna be able to do well today? Form new memories. Also, your hippocampus consolidates the information you're learning into a lasting memory that you can consciously retrieve while you sleep. So what happens if you don't get enough sleep? Your hippocampus might not have had enough time
• 05:00 - 05:30 to do the job, and so your memories from what happened yesterday and the stuff you learned yesterday, might not be fully formed today, or they might not be formed at all. Caffeine is actually good for memory, because caffeine increases your attention. So anything that's an attention booster is gonna be a memory booster. We know that sleep is super important for forming memories,
• 05:30 - 06:00 so caffeine's good for memory. You just wanna be careful that it's not compromising your sleep. Our brains are not designed to remember people's names. These are abstract concepts. They live in neurological cul-de-sacs. Ultimately, there's only one way into that house that lives at the end of that street, and there's no other way to get there. So can we supply more associations to the person's name to give us a chance?
• 06:00 - 06:30 In psychology, this is called the 'Baker-Baker Paradox.' If I'm trying to remember your name and your name is Mr. Baker, that's really tough for me to remember- abstract concept. But if I were asked to remember the word "baker," I can picture him wearing an apron, and he's got flour on his face and, "Oh, I remember the bakery I used to love as a kid and we used to get danishes there on Sundays." So now I've got all of these associations in my brain,
• 06:30 - 07:00 attaching to that word "baker," and gives me a chance to hook into it. For all of these memories, they benefit from repetition. The more we repeat, the more we practice, the more we rehearse a memory, we are strengthening those neural connections, making that neural circuit stronger, and more likely to be fully retrieved. One of the ways that we can repeat a memory is by writing it down. If I've experienced a certain number of things today,
• 07:00 - 07:30 and I keep a journal- what I've chosen to write down will become a stronger, more reinforced memory in my brain. I will also have the opportunity to revisit that memory by reading it later. So many people come up to me, so worried, saying, "If I don't write what I need to do later down, I'm gonna forget to do it. That's gotta mean I'm getting Alzheimer's." And I tell all of them, "No, it's your prospective memory. It's terrible.
• 07:30 - 08:00 It's not cheating to write it down. It's actually good practice." Airline pilots do not rely on their brains and their prospective memories to remember to lower the wheels before landing the plane. They outsource the job to a to-do list, a checklist. We should all write it down, put it in your phones, put it in your calendar alerts, make to-do lists. If you wanna remember to pick up milk at the grocery store,
• 08:00 - 08:30 write it down. Another way to better remember this information has to do with self-testing. If I'm trying to consolidate something into memory, and I'm only putting the information in, I'm traveling one way on the neurons. If I then try to recall the information, I'm pulling the information out- now I'm going the other way. Going over those circuits in both directions will help reinforce and make that memory stronger.
• 08:30 - 09:00 Okay, having a word stuck on the tip of your tongue is a normal glitch in memory retrieval. It's just a byproduct of how our brains are organized. So looking up a word, Googling a word that's on the tip of your tongue isn't cheating. It will not cause digital amnesia. It will not make your memory weaker in any way. It frees you up. We can Google anything that we can't remember in a moment's notice, and then use that information
• 09:00 - 09:30 to continue thinking, to continue the conversation, to learn more. You have my permission to Google it and look it up. What I would love for you to take away from all of this is that your memory is amazing. It is limitless in what it's capable of remembering if you supply it with the right kind of information, if you supply it with the right kind of tools and associations.
• 09:30 - 10:00 And it's wildly imperfect, and that's just the price of owning a human brain. Forgetting is a normal part of being human.
