The human brain is both the world’s most adept learner and greatest translator. From infancy and throughout development our brains rapidly learn how to take basic physical properties such as light, pressure, and time and transform them into the most complex of human capacities such as thought, memory and imagination. This translation arises via billions of nanoscopic transmissions that flow across a vast yet infinitesimal labyrinth of neurons. Once opaque, the immense neural maze of the brain is now recognized as being organized into coordinated yet discrete specialized systems, each composed of a series of distributed regions throughout the brain.
​
Specific research questions:
​​​
-
How do our experiences, particularly stressful ones, shape the way our neural systems function, and thus how we engage with the world around us?
-
How can we best capture (ie. quantify) someones "stress"?
-
How do we best identify the neural systems in our brains so their relative contributions to cognition can be examined?
