The Disruptive Power of Exercise: Dr. Wendy Suzuki (Transcript)

Full text of neuroscientist Wendy Suzuki’s talk: The disruptive power of exercise at TEDxACCD conference. In this talk, Dr. Suzuki describes the neuroscience behind why exercise is the new magic bullet for your brain.


Dr. Wendy Suzuki – Neuroscientist & fitness instructor

Thank you so much Henry. Such an honor to be here.

So I am a neuroscientist. And in science, we have disruptive ideas, we call them paradigm shifts.

Now we typically think of a paradigm shift as Earth’s shadow, something that breaks the mold, something that destroys old dogma.

But the truth is that a paradigm shift can also be quiet and personal, yet still quite profound.

What I’m going to do today is tell you about a series of what I call cascading paradigm shifts, that really brought me to where I am today. And they start with one of those personal quiet shifts.

So my first story starts back in 1998 when I was a young assistant professor starting my first research position… professor position at New York University. I was so excited to start designing my own experiments, building my own lab. I was the most excited science nerd that you could ever imagine.

And the question that I was focused on was: what is the pattern of electrical activity in brain areas important for long-term memory? The one key brain structure I focused on is a structure called the hippocampus.

Now when I think back on those early years of starting my lab, the atmosphere in the lab reminds me of a fantastic dinner party that you never want to leave, because there was always something… somebody interesting to talk to and an interesting topic to talk about.

So that was the research lab.

By contrast, during that same time, if I think back on my personal life, the image that comes to mind is a dusty western deserted town from a Clint Eastwood Western with tumbleweed, you know swirling in the street, bone-dry.

I had no friends outside the lab, because I was working all the time. I went and ate take-out all the time. So few years in, I was 20 pounds overweight. And that part of my life was in desperate need of a paradigm shift.

Well, my inspiration for that actually came in an unlikely place on a river rafting trip in Central Peru where I found myself the weakest person on the entire trip. There were 16 year-olds that were stronger than me, and there were 60 plus year-olds that were stronger than me.

And I came home and I said, “No way, I’m never going to feel like the weakest person on the trip again.”

I went to the closest gym and signed up for a trainer. And this time it worked my exercise regime stayed in place. And I’ll tell you the secret. The thing that helped me really stay with this exercise program was a class that I found at the gym.

It’s a unique class developed by this amazing exercise instructor named Patricia Moreno, and this exercise called intenSati combines physical movements from kickboxing, dance, and yoga and martial arts, and [Pearson] with positive spoken affirmations.

So intenSati, we say I am strong now, or I believe I will…

OK. I’d go to these classes and I’d be sweating and yelling affirmations a whole bunch of other sweaty affirmation yelling people and I come out of class feeling pumped up. I felt like a million bucks.

And so what this did is it raised my energy levels, it raised my mood, and not only that, it actually helped revive my bone-dry social life because I started meeting friends, meeting new people at the gym.

But actually the most amazing thing that I noticed was when I was at work. So I write a lot of rants, and what I was noticing with this regular exercise is that my attention span was deeper and longer than it had ever been.
