“The wiring of the brain is never complete” Lisa Feldman Barrett, Ph.D.“The brain’s ability to rewire neurons throughout our life” is called brain plasticity, the psychologist and neuroscientist said in a class called “The Science of Ageing Wiser.”
Acquiring brain plasticity in adulthood may be more difficult and take longer, but it’s not impossible, said Barrett, who also serves as chief scientific officer at the Center for Law, Brain and Behavior at Massachusetts General Hospital.
“Thanks to the amazing capabilities of brain plasticity, we can alter brain health and improve brain anatomy, physiology and function,” he said. Dr. Wendy SuzukiNeuroscientist and Dean of the College of Arts and Sciences at New York University.
Think of it as a “supercharged 401(k) for your brain,” Suzuki says. “Everything you do throughout your life will promote the long-term brain health of all of us.”
These are some suggestions from experts featured in the MasterClass series for improving your brain health and keeping your mind clear.
1. Try something new or challenging
“When you encounter something that you didn’t expect or anticipate, and it has the potential to be useful in the future, your brain will try to learn it,” Barrett says, “and learning is plasticity.”
To get the greatest benefit to brain health, experts stressed, the experience needs to be new and challenging — “challenging enough that it makes you a little uncomfortable,” Barrett said.
Barrett and Suzuki suggested getting involved in the following activities:
- Read a new book
- Learn a new language
- People I’ve never met before
- Perform in a play
- Travel to places you’ve never been before
- Watch new movies
- Play fun memory games, such as memorizing a shopping list
The goal should be “optimal novelty, optimal difficulty, optimal challenge,” Barrett says. “All of these things are metabolically difficult right now, but they’re like investments in becoming a healthier, stronger version of yourself.”
2. Be physically active
“Physical activity has a tremendous impact on the brain,” Suzuki said. “Physical activity stimulates the growth of new brain cells in the adult hippocampus,” he added. This process is called neurogenesis.
This process is most effective with regular exercise, Suzuki says.
“10 minutes of walking has been shown to significantly reduce levels of depression and anxiety,” she says. “Activities that require strategy engage the prefrontal cortex more,” she says, and this includes sports like soccer and basketball.
Even a little bit of exercise can help, she points out: “Every drop of sweat counts for your brain.”
3. Connect with others
Having more social interactions with people you’re not close to also helps predict longevity, Suzuki says: “Laughter and enjoyable social interactions lower stress levels.”
Going for a walk or eating a healthy dinner has an even better effect on your brain if you do it with people you enjoy.
Through acts of kindness and community service, you can also experience the release of dopamine, the hormone that makes you feel happy.
4. “Be the architect of your own emotions.”
Training your brain to be more flexible in generating emotions and building your emotional intelligence can have huge benefits for your brain health.
“There’s a big difference between dealing with distress as sadness or anger and understanding distress as, ‘I’ve had a really rough week and I need to take a little bit of self-care,'” Barrett said.
No emotion is inherently good or bad, but if we are flexible, we can channel our emotions in productive ways.
Another effective technique is what Suzuki calls “conditioning of pleasure,” which involves recalling a positive memory from the past and then confronting or replaying that emotion.
Ultimately, a 401(k) for your brain can be summed up in these words from Suzuki: “Move your body, get brain-optimizing sleep, eat a Mediterranean diet, and have strong social connections. [and] Wishing you as much love and laughter as you can in your life.”
