Cognitive Network Neuroscience

We examine how human brain networks support cognition. For more than 100 years, studies of brain anatomy have taught us about brain structure, and innovations in neuroimaging allow us to study how structure and brain function relate to cognition. We use multiple imaging methods (such as fMRI, EEG, and structural imaging) and network analyses to study individual differences. Pictured below moving left to right, we can understand brain structure as a set of regions with specialized neural functions that operate in complex networks. We can then attempt to map brain systems in various ways with neuroimaging.

Brain Stimulation

Noninvasive brain stimulation (e.g., transcranial magnetic stimulation, TMS; transcranial direct current stimulation, tDCS) is increasingly used in experiments and clinics . We combine neuroimaging, brain stimulation, and computerized testing to improve cognition. We use brain network structure and function to describe and predict responses to brain stimulation. A new arm of the lab involves tracking and stimulating the brain in real time, also known as “closed loop” stimulation.

Neuroethics

What do people think is right and wrong to do with neuromodulation - and why?
As new technologies penetrate clinics, laboratories, and the public market, neuroethical discussions and regulation are challenged with new frontiers. CogNeW studies the psychology of decision making for neuroethics among the public and experts. We seek to understand individuals' preferences and biases about existing and new approaches to modifying the human brain. These studies could help anticipate undesirable "anti-zapper" and "zappo-phile" trends among the public and experts and inform neuroethics, public policy, and education for neuromodulation. We have performed public opinion surveys to understand how people evaluate specific uses of brain stimulation to enhance cognition.
