Wendy Suzuki: The brain-changing benefits of exercise | TED
TED・2 minutes read
Physical activity has immediate, long-lasting, and protective benefits for the brain, guarding against conditions like depression and Alzheimer's. Regular exercise can lead to the formation of new brain cells in the hippocampus and enhance long-term memory.
Insights
- Physical activity offers immediate and lasting protection for the brain, potentially guarding against conditions like depression, Alzheimer's, and dementia by promoting the formation of new brain cells and enhancing long-term memory.
- Regular exercise not only improves attention function and increases hippocampal volume but also has immediate effects on neurotransmitters, such as dopamine and serotonin, boosting mood and attention. Aim for three to four aerobic sessions weekly, lasting at least 30 minutes each, for significant brain benefits without requiring an expensive gym membership.

Recent questions
How does physical activity benefit the brain?
Physical activity has immediate, long-lasting, and protective benefits for the brain. It can guard against conditions like depression, Alzheimer's, and dementia. Exercise leads to the formation of new brain cells in the hippocampus, enhancing long-term memory. It also improves attention function, particularly in the prefrontal cortex, and increases hippocampal volume. Additionally, exercise has immediate effects on neurotransmitters like dopamine, serotonin, and noradrenaline, enhancing mood and attention. Regular exercise can change the brain's anatomy, physiology, and function, providing long-lasting benefits and acting as a protective measure for the brain.
What experiment did the neuroscience professor conduct?
The neuroscience professor conducted an experiment on herself to understand the brain-changing effects of exercise. This experiment likely involved engaging in regular physical activity and monitoring the cognitive and emotional changes that occurred as a result. By personally experiencing the impact of exercise on the brain, the professor gained firsthand insights into the benefits of physical activity on brain health and function.
How does exercise impact neurotransmitters?
Exercise has immediate effects on neurotransmitters like dopamine, serotonin, and noradrenaline. These neurotransmitters play crucial roles in regulating mood, attention, and overall brain function. By enhancing the levels and activity of these neurotransmitters, exercise can improve mood, attention, and cognitive performance. This highlights the powerful impact that physical activity can have on the brain's chemical signaling pathways and overall mental well-being.
What is the recommended frequency of aerobic exercise?
To reap the benefits for the brain, it is recommended to aim for three to four aerobic exercise sessions per week, each lasting at least 30 minutes. This frequency and duration of exercise can help enhance brain health, cognitive function, and emotional well-being. Importantly, these exercise sessions do not require an expensive gym membership, making it accessible for individuals to incorporate physical activity into their routine for optimal brain health benefits.
How does long-term exercise affect brain anatomy?
Long-term exercise can change the brain's anatomy, physiology, and function. It leads to the formation of new brain cells in the hippocampus, enhancing long-term memory. Exercise also improves attention function, particularly in the prefrontal cortex, and increases hippocampal volume. These structural changes in the brain as a result of long-term exercise contribute to improved cognitive function, mood regulation, and overall brain health.
