Objective: Auditory processing disorders are common in patients with epilepsy and adversely impact verbal communication. The neural bases of auditory disorders remain poorly understood, impeding development of objective clinical tests. The overall goal of this project is to develop an objective clinical measure of auditory processing using computational modeling of functional brain connectivity. To address this goal, we will use novel functional connectivity methods to analyze magnetoencephalographic (MEG) and intracranial electrocorticographic (ECoG) recordings.
