7 Key Concepts
Hippocampus
This brain structure, shaped like a seahorse, is crucial for forming new long-term memories for facts and events. Beyond memory, it's also vital for imagination, allowing us to combine existing information in novel ways to envision future or hypothetical scenarios.
One-Trial Memory
This refers to the rapid formation of memories after a single experience, often for emotionally salient or potentially dangerous events. This process leverages an evolutionarily developed system, often involving the amygdala, to quickly 'stamp in' information crucial for survival.
BDNF (Brain-Derived Neurotrophic Factor)
BDNF is a growth factor released particularly with aerobic exercise that directly stimulates the hippocampus. It helps brand new brain cells grow in the hippocampus, contributing to a 'bigger, fatter, fluffier hippocampus' that can better resist age-related cognitive decline.
Myokine Pathway
This is one mechanism by which exercise benefits the brain, involving proteins released by working muscles. These myokines can cross the blood-brain barrier and stimulate the release of BDNF within the brain.
Ketone Pathway
Another mechanism for exercise's brain benefits involves beta-hydroxybutyrate, a ketone released by the liver during exercise. This ketone also passes the blood-brain barrier and acts as a stimulant for BDNF production.
Neurogenesis
This is the process of new neuron production, which can occur in the adult human brain, specifically in the hippocampus, even into old age. Regular exercise, particularly cardiovascular, is shown to promote neurogenesis.
Mindset and Affirmations
One's beliefs about a behavior significantly impact its physiological and psychological outcomes, a concept known as mindset. Positive affirmations, especially when spoken aloud, can shift mood and self-image by countering negative internal dialogue and fostering beneficial self-perception.
8 Questions Answered
Memorable experiences are characterized by novelty, repetition, association with existing knowledge, and emotional resonance. The amygdala and hippocampus interact to 'stamp in' emotionally significant memories.
Without a functioning hippocampus, individuals lose the ability to form new long-term memories for facts and events, and they are also unable to imagine new situations or events they haven't experienced before.
Just 10 minutes of walking, even indoors, can significantly shift your mood by releasing neurochemicals like dopamine, serotonin, and noradrenaline.
The immediate cognitive benefits of a single 30-45 minute aerobic exercise session, such as improved focus and reaction time, can last for at least two hours after the workout is completed.
The neuroscience data suggests the best time to exercise is right before you need to use your brain in the most important way, which for most people means early in the morning to leverage the subsequent cognitive boost.
Yes, for individuals already exercising 2-3 times a week, increasing workout frequency up to seven times a week can lead to further improvements in mood, reduced depression and anxiety, and better hippocampal function.
Meditation, even short daily sessions, improves cognitive performance and reduces stress response primarily by training the brain to focus on the present moment, counteracting tendencies to dwell on past regrets or future anxieties.
The top three tools to increase attention are regular exercise, consistent meditation, and sufficient sleep, with sleep being the most fundamental physiological requirement for all core cognitive functions.
12 Actionable Insights
1. Prioritize 7.5-8 Hours Sleep
Aim for 7.5 to 8 hours of sleep every night to improve willingness to tackle difficult tasks, enhance persistence, and ensure your brain works better for overall cognitive function.
2. Daily Cardiovascular Exercise
Engage in regular cardiovascular exercise, aiming for 30-45 minutes daily, or as frequently as possible, to release neurochemicals and BDNF, which improves mood, attention, and promotes the growth of new brain cells in the hippocampus.
3. Exercise Early for Brain Function
Perform your exercise early in the day, ideally right before you need to engage in important cognitive work, to maximize immediate benefits like improved mood, prefrontal function, and reaction time for up to two hours.
4. Daily 10-12 Minute Meditation
Practice a 10-12 minute guided body scan meditation daily to significantly decrease stress response, improve mood, and enhance cognitive performance by training focus on the present moment.
5. End Showers with Cold Blast
Finish every morning shower with a big blast of cold water to increase adrenaline, epinephrine, norepinephrine, and dopamine, leading to improved mood, alertness, and a lasting feeling of awakenedness.
6. Make Information Memorable
To enhance memory formation, leverage novelty (newness), repetition, association (linking to known information), and emotional resonance (making it funny, surprising, happy, or sad).
7. Increase Exercise Gradually
If currently exercising less than 30 minutes per week, start with 2-3 times a week of 45-minute cardiovascular exercise (e.g., spin class) to improve mood, body image, motivation, attention, and hippocampal-dependent memory.
8. Maximize Exercise Frequency
If already exercising 2-3 times a week, increase cardiovascular exercise frequency up to seven times a week if possible, as every additional session improves mood (lower depression/anxiety) and hippocampal function.
9. Cultivate Positive Mindset
Learn about the positive effects of behaviors like stress and exercise to cultivate a positive mindset, as your beliefs about a behavior can physiologically impact its outcomes and lead to greater benefits.
10. Practice Positive Self-Affirmations
Regularly practice positive self-affirmations, ideally spoken aloud (e.g., ‘I’m strong,’ ‘I’m inspired’), to counteract negative inner dialogue, improve mood, and build a positive self-image.
11. Practice Tea Meditation
Engage in a 45-minute tea meditation, meditating over the brewing and drinking of tea, as a specific practice for focus and mindfulness.
12. Utilize Free Online Resources
Leverage free online resources like YouTube for guided meditations or exercise routines if you don’t want to join classes or prefer self-guided practice.
5 Key Quotes
Every single time you move your body, you are releasing a whole bunch of neurochemicals.
Dr. Wendy Suzuki
We all have the capacity to grow a bigger, fatter, fluffier hippocampus.
Dr. Wendy Suzuki
Every drop of sweat counted, that is, the more you change and you increase your workout up to seven times a week, the better your mood was.
Dr. Wendy Suzuki
I'm so mean to myself. I have lots of negative thoughts going on about myself in my head.
Dr. Wendy Suzuki
The ability to focus and attend is really the distinguishing feature between those that will succeed in any endeavor and those that won't.

2 Protocols
Dr. Suzuki's Morning Brain-Enhancing Routine
Dr. Wendy Suzuki- Wake up and engage in a 45-minute tea meditation, focusing on the brewing and drinking process.
- Perform a 30-minute cardio and weights workout.
- Take a shower, ending with a significant blast of cold water for contrast.
- Ensure 7.5 to 8 hours of sleep nightly by going to bed earlier.
Exercise Protocol for Improving Cognition in Low-Fit Individuals (30s-50s)
Dr. Wendy Suzuki- Engage in cardiovascular exercise (e.g., spin class) 2 to 3 times per week.
- Each session should be approximately 45 minutes, including warm-up and pushing heart rate up.
- Maintain this regimen for at least 3 months.
