CRONELAB: Cognitive Research, Online Neuroengineering, and Electrophysiology


Nathan Crone, M.D. is an Associate Professor of Neurology and director of the Cognitive Neurophysiology and Brain-Machine Interface Laboratory. Dr. Crone leads a long-standing research program using intracranial EEG to study human brain mechanisms of language, attention, and motor function. This research is carried out in patients undergoing intracranial EEG monitoring prior to epilepsy surgery. Dr. Crone serves as an attending neurologist in the Johns Hopkins Hospital where his clinical work focuses on the management of drug-resistant epilepsy, electroencephalography, and intraoperative monitoring. Dr. Crone's technical expertise is in the fields of cognitive neuroscience and neurophysiology, including the rapid characterization and application of human neurophysiological responses for both functional brain mapping and brain-machine interfaces.

Anna Korzeniewska, Ph.D. studies dynamics of cerebral functional and/or pathological connectivity to identify brain networks responsible for diseases and distinguish them from brain networks responsible for motor, language, and other cognitive functions. Anna develops advanced mathematical methods and applications for determining information flow within neural networks, and is interested in translational research aimed to help people with brain diseases or dysfunctions.

Graduate Students

Guy Hotson

Yujing Wang Email

Yujing is a Ph.D. student majoring in Bioengineering at the University of Maryland. She is developing a trial-based online functional mapping system that complements electrocortical stimulation mapping in patients undergoing neurosurgical resections for epilepsy or tumors. She will use this system to collect and analyze ECoG data from auditory and language experiments.

Technical Staff

Max Collard

Max Collard B.S. '15 Email

Max investigates the computation of cortical subnetworks as a means of simplifying the analysis and interpretation of high-dimensional connectivity data. He is interested in using subnetworks to better understand the cortical interplay that occurs during cognitive tasks, and as a possible methodology for probing neurophysiological phenomena like frequency multiplexing or cross-frequency coupling.
