A story of movement, memory, and mentors. Dr. Wendy Suzuki introduces us to Dr. Marian Diamond, whose lively classes ushered Wendy into a career in neuroscience. And Wendy shares how she came to study how exercise profoundly affects the brain, not just the body.
Here’s more from Wendy:
A science mentor can make your career. Dr. Marian Diamond not only ushered me into the field of neuroscience with her lively and engaging classes but she has continued to influence me and help me throughout my work as a scientist and teacher.
What made Marian such a profound mentor? Her multi-dimensionality. First, she was the best teacher I have ever experienced in my entire thirty-year career, unendingly fascinated with her specialty, human anatomy, including both brain anatomy and gross human anatomy. Now, if you have never taken an anatomy course before, you should know it can be as dry as learning last year’s tax laws. Marian made anatomy come alive, relating every brain or body part to a question or observation about ourselves, such as “The word uterus means Hysterical- do you agree with this?” Or “Do you know what the largest organ in the body is? It’s your skin- take care of it!” She made anatomy relevant and personal.
Second, she made groundbreaking scientific contributions on the capacity of the brain to change in response to the environment. When she did this work in the late 1950s/early 1960s, nobody believed that the adult brain could change – at least in any ways that scientists could measure. Marian and her colleagues showed that changing a rat’s living space (what she called “enriching” the environment) could have profound effects of the brain’s anatomy and that she could measure them. In this episode, I’ll describe Marian’s pioneering studies and how they related to recent studies showing the profound ways that exercise transforms the brain.
Third, she offered me a role model of a thriving, engaged and enthusiastic female scientist, even if it took me years to appreciate how lucky I was. You see, she was such a powerful presence on the Berkeley campus that I thought that smart strong, successful female neuroscientists who were extraordinary teachers were everywhere! I never questioned whether I would be able to do the same thing, because she showed me that it could be done. Only much later into my post-doctoral studies did I notice that other female scientists didn’t seem to have the same confidence that I did; they saw the sea of men in science with only a few successful women and many found it discouraging.
Only later was I able to fully appreciate what a wonderful gift she gave me as my role model in science. Because Marian did the work she loved, she allowed me to sail right over worries over whether a woman could make it.
In this episode, we’ll hear from Marian herself, as she teaches a class and describes her groundbreaking findings. Her work on brain plasticity is at the heart of the work that I and many neuroscientists pursue today.
