Research Abstract: 

Electroencephalography (EEG) is an indispensable neurological diagnostic tool in terms of fast time scale, portability, and cost efficiency. Improved spatial resolution of EEG measures would greatly benefit clinical and research applications, including stroke, epilepsy, and cognitive studies. Dense-array EEG recordings can be used to localize cortical function, providing a unique opportunity for monitoring brain activity both in space and time. Localizing brain function using EEG can be further optimized by use of realistic head models and incorporating accurate conductivity estimates for each tissue type of the head model. Lack of accurate skull conductivity information is particularly problematic given the variations in skull development from infancy through adolescence. The goal of this project is to develop technology based on Electrical Impedance Tomography (EIT) for conductivity estimation to guide EEG source localization.
