Roozbeh Behroozmand, PhD

Director, Speech Neuroscience Lab Roozbeh Behroozmand, PhD, is an Assistant Professor of Communication Disorders (COMD) and the Director of Speech Neuroscience Lab in the Arnold School of Public Health at the University of South Carolina. Dr. Behroozmand has background in Biomedical Engineering and Neuroscience and his research is focused on investigating the neural bases of speech production and motor control in the human brain. His lab utilizes a wide range of techniques including electrophysiology (EEG, ERP, ECoG), functional neuroimaging (fMRI) and high-definition transcranial direct current stimulation (HD-tDCS) to study sensory-motor mechanisms of speech in healthy individuals and patients with neurological disorders. The ultimate goal of this research is to gain knowledge that can be translated into the development of novel diagnosis and clinical treatment methods to enhance speech communication and improve quality of life in patients with speech disorders.

Caroline Hayden

Undergraduate Student Caroline Hayden took part in a joint collaboration with the Neurolinguistics Lab (Dr. den Ouden) and the Speech Neuroscience Lab (Dr. Behroozmand), as part of a Magellan Scholar Award on a project to investigate how non-invasive neurostimulation can affect speech motor control ability in the human brain. She used the state-of-the-art HD-tDCS (High-definition transcranial direct current stimulation) technique and combined it with electroencephalography (EEG) to measure changes in brain activity before and after neurostimulation during a speech motor control task. The goal of this research is to determine whether neurostimulation affects the ability to better control speech, and use the neurostimulation technology for the treatment of speech motor disorders in patients with neurological impairments such as Parkinson’s disease.
