PI: Karim Johari, Ph.D.

 

Dr.  Johari is an assistant professor in the department of communication sciences and disorders. He utilizes invasive (ECog), non-invasive neurophysiology (EEG),  HD-tDCS/tACS and computational modeling to investigate neural correlates of speech production, and the interaction between the motor system and language ( motor-language coupling)in healthy subjects and patients with neurological conditions. The current project in his lab isthe validation of HD-tACS for improvement of speech and limb motor control in healthy older adults and individuals with neurodegenerative conditions such as Parkinson’s disease.
