The Center for Consciousness Science (CCS) conducts studies across the translational spectrum, from computational brain models, to experiments in animals, to studies of healthy humans, to clinical trials in patients.

Furthermore, our basic science research program includes neural circuit manipulation through pharmacological, electrical stimulation, chemogenetic, and optogenetic techniques. The CCS has deep expertise in analyses involving graph theory, advanced functional connectivity measures, and neural dynamics. We are fortunate to have robust support from the National Institutes of Health and have had major grants from the James S. McDonnell Foundation.
