The Zuckerman Institute at Columbia University is involved in cutting-edge research on the brain and mind. I created this gif-ographic (like an infographic, but with simple animation) to explain the research of Randy M. Bruno, PhD, a researcher at the Zuckerman Institute. Dr. Bruno studies cognition - a complex coordination by billions of neurons to create our sophisticated thoughts and emotions. When reading about his research, some of the conclusions reminded me of my training in music, so I thought that would be a good way to explain this area of neuroscience. For more information on his research, view the Zuckerman Institute website.
Epigenetics help the aging brain
This review paper summarizes recent research showing how epigenetics change the brain as we get older.

Excitation and inhibition: The yin and yang of the brain
A correct balance of excitation (passing on activity) and inhibition (dampening down activity) is crucial to a normally-functioning brain. I created this infographic to describe how important this balance is. See the full post: http://knowingneurons.com/2017/01/25/excitation-inhibition/

How does basic science research help you?
Sometimes it’s hard to understand why scientists do what they do. Why spend a career studying cells, fungus, or flies? Other than being nerdy and wanting to learn about our world, what’s the point?
Last month I had the opportunity to attend Sunposium, a neuroscience research conference hosted by the Max Planck Florida Institute for Neuroscience in West Palm Beach, Florida. I love everything brain-related, so every talk was captivating for me, but through the jargon, methods, and neon images, an incredibly important message shone through: fundamental or basic research, research that asks fundamental questions about our world is critical to our society. The scientists who presented their research, including two Nobel prize winners and many other young researchers with promising careers, study everything from bacteria to birds to humans. The questions they ask aren’t about how to cure illnesses or treat disease. But the breakthroughs they have made will impact human health in the near future. Fundamental research is critical to science because it allows for unexpected and unpredictable breakthroughs.
Check out the infographic below to explore what I learned at this incredible conference.
Make the most of a bilingual childhood
I helped write a paper describing how parents and teachers can help bilingual children develop most effectively! Below is a visual summary. Read the full paper here: The Developing Bilingual Brain: What Parents and Teachers Should Know and Do
How to be a better learner
I created this infographic as part of my team's submission to a contest to redesign high school: http://xqsuperschool.org/challenge
One of the goals of our project is to create students who are passionate about learning and can do so independently. So these techniques can be used by anyone to take control of their own learning.
