安德鲁·休伯曼博士采访了温迪·铃木博士，她是神经科学领域的领军人物，专攻学习和记忆。他们讨论了记忆形成的神经科学原理，以及增强认知功能的实用策略。 铃木博士概述了使体验令人难忘的四个关键要素：新颖性、重复性、关联性和情感共鸣。情感事件会触发杏仁核，进而增强海马体编码长期记忆的能力。海马体的形状像海马，对于将事实和事件巩固为持久记忆至关重要。这个过程定义了我们的个人历史，以及至关重要的，我们以新颖的方式想象和关联信息的能力。 对话深入探讨了海马体除了简单存储之外的作用。虽然长期记忆存在于大脑皮层，但海马体充当中间存储区域，可能持续数年。由于进化的生存机制优先考虑记住潜在威胁，情感显著的事件会产生一次性记忆。 这得益于杏仁核和海马体之间的强大连接，将地点与身体状态，以及状态与地点联系起来。 铃木博士讲述了她从一个压力巨大的工作狂到健身爱好者的个人历程。她观察到，在日常生活中加入规律的锻炼后，她的专注力、记忆力和撰写拨款申请的能力都有所提高。意识到锻炼在对抗认知衰退方面的潜力，她开始研究体育活动对大脑功能的影响，特别是它通过释放脑源性神经营养因子 (BDNF) 促进海马体神经发生的能力。每一次运动都会让大脑沐浴在神经化学物质的“泡泡浴”中，支持更大、更健康的海马体生长。 具体而言，有氧运动因其对前额叶皮层和海马体的影响而显得尤为有益。有两个途径负责发送信号。首先，肌肉活动释放的肌细胞因子会穿过血脑屏障并刺激 BDNF 的释放。其次，肝脏产生酮类物质β-羟基丁酸酯作为对运动的应激反应，它也会穿过血脑屏障并促进 BDNF 的释放。 铃木博士讨论了她尚未发表的研究，这些研究证明了锻炼对记忆的影响。她已经证明，每周锻炼两到三次的低适应性人群，其情绪、身体形象和运动的积极性都有所提高。同样，有规律的锻炼也被证明可以提高识别记忆和空间情景记忆，这与海马体功能密切相关。她还提到，对于中等适应性的人群，将他们的锻炼增加到每周七次，可以使他们的情绪和海马记忆更好。 对话扩展到包括积极肯定的影响，以及通过在体育活动期间保持正念来增强锻炼益处的潜力。铃木博士强调了尽早养成良好习惯以及通过每天在同一时间锻炼来利用昼夜节律系统的重要性。她提倡对于那些刚开始锻炼的人来说，每天至少运动10分钟的重要性，并且要在户外运动，让阳光照射到眼睛。 铃木博士强调，锻炼、冥想和睡眠是增强注意力的三大零成本工具。冥想，即使是短短的 10-12 分钟，也能培养专注于当下并对抗现代生活中的干扰的能力。

Dr. Andrew Huberman interviews Dr. Wendy Suzuki, a leading neuroscientist specializing in learning and memory, to discuss the neuroscience of memory formation and practical strategies for enhancing cognitive function. Suzuki outlines four key elements that make experiences memorable: novelty, repetition, association, and emotional resonance. Emotional events trigger the amygdala, which then enhances the hippocampus's ability to encode long-term memories. The hippocampus, shaped like a seahorse, is critical for consolidating facts and events into lasting memories. This process defines our personal histories and, crucially, our ability to imagine and associate information in novel ways. The conversation delves into the hippocampus's role beyond simple storage. While long-term memories reside in the cortex, the hippocampus acts as an intermediate storage area, potentially for years. Emotionally salient events create one-trial memories due to the evolved survival mechanism that prioritizes remembering potential threats. This is facilitated by the strong amygdala-hippocampus connection, linking place to bodily state and state to place. Suzuki discusses her personal journey from a stressed workaholic to a fitness enthusiast. She observed improved focus, memory, and grant-writing ability after incorporating regular exercise into her routine. Realizing the potential of exercise to combat cognitive decline, she began studying the impact of physical activity on brain function, particularly its ability to promote neurogenesis in the hippocampus through the release of brain-derived neurotrophic factor (BDNF). Every instance of movement bathes the brain in a "bubble bath" of neurochemicals that supports the growth of a bigger, healthier hippocampus. Specifically, aerobic exercise stands out as beneficial due to its effects on the prefrontal cortex and hippocampus. Two pathways are responsible for sending the signals. Firstly, muscle activity releases myokines that cross the blood-brain barrier and stimulate BDNF release. Secondly, the liver produces the ketone beta-hydroxybutyrate as a stress response to exercise, which also crosses the blood-brain barrier and promotes BDNF release. Suzuki discusses her unpublished studies that demonstrates exercise's effects on memory. She has shown low-fit people who exercise two to three times a week experience improved moods, body images, and increased motivation to exercise. Likewise, regular exercise has also been shown to improve recognition memory and spatial episodic memory, which is strongly related to the hippocampus function. She also mentioned that in midfit people, increasing their work out up to seven times a week makes their mood and hippocampal memory even better. The conversation expands to include the impact of positive affirmations and the potential to enhance the benefits of exercise by being mindful during physical activity. Suzuki emphasizes the importance of establishing good habits early and leveraging the circadian system by exercising at the same time each day. She advocates for the importance of moving one's body for at least 10 minutes a day for those who are new to exercise, and moving outside to allow sunlight reach the eyes. Suzuki emphasizes that exercise, meditation, and sleep are the top three zero-cost tools for enhancing attention. Meditation, even in short 10-12 minute sessions, cultivates the ability to focus on the present moment and combat the distractions of modern life.
