Non-invasive Imaging and Boosting the Human Brain by NIR Light - Frontiers of BrainHealth Lecture
Friday, Apr. 19
noon - 1 p.m. Location: International Reception Hall, Center for BrainHealth

The Center for BrainHealth invites scientists to share their scientific study with students and other researchers at the BrainHealth Frontiers Lunch Lectures. The lectures are heavily science focused and are not intended for a lay audience. This lecture will be held at the Brain Performance Institute - The Ellipse, 2200 West Mockingbird Lane.

Topic is Non-invasive Imaging and Boosting the Human Brain by NIR Light

It has been well known that near infrared (NIR) can be used to non-invasively image functional activities of the human brain during cognitive tasks at different age groups, particularly for studying children and other vulnerable groups with neurological disorders. In addition, recent studies have demonstrated that NIR laser or light emitting diodes (LEDs) can be used for transcranial photobiomodulation (tPBM), which may serve as a promising neuromodulation tool for treating a variety of neurological brain disorders.

In this talk, I will cover several sub-topics of my research: (1) principle of light-brain interaction, (2) examples of NIR optical imaging of human brain activities in post-traumatic stress disorder (PTSD) subjects performing Stroop and Digit-Span tasks, (3) demonstration of tPBM with 1064-nm laser applied on human participants and its working principles, and (4) significant alterations in tPBM-induced electrophysiological patterns across the entire human head, determined by 64-channel EEG measurements. The last part of this talk intends to shed light on the mechanism of action of tPBM, which is a new form of transcranial neuromodulation.

Dr. Hanli Liu is an internationally recognized researcher in the field of near infrared spectroscopy for cancer detection and functional brain imaging. She received her MS and PhD degrees in physics from Wake Forest University, followed by postdoctoral training at the University of Pennsylvania. She is a Full Professor of Bioengineering and Distinguished University Professor at the University of Texas at Arlington. She is also a Fellow of American Institute for Medical and Biological Engineering. Her expertise lies in the field of near-infrared spectroscopy of tissues, functional optical brain imaging, transcranial photobiomodulation, and their clinical applications. In recent years, Dr. Liu has extended her research expertise in measurements and data analysis of 64-channel electroencephalography (EEG) for monitoring transcranial photobiomodulation (or called neuromodulation), which has the great potential to become a non-invasive therapeutic tool to treat neurological diseases in the near future. Over the last 20+ years, Dr. Liu has (1) obtained external research funding in the field of optical imaging and brain stimulation more than $10M, (2) published over 130 peer-reviewed journal papers and 135 conference abstracts, and (3) been invited to deliver more than 60 scientific seminars nationally and internationally.
