Episode #125: Optogenetics: New Discoveries in Laser Therapy & Brain Health with Dr. Trevor Berry

The Science of Light: How Laser Therapy Influences the Brain and Body The Laser Light Show | Dr. Chad Woolner & Dr. Trevor Berry What if light does far more than help us see? What if specific wavelengths could influence cellular activity, nervous system function, and the way our bodies respond to the world around us? In this episode of The Laser Light Show, Dr. Chad Woolner and Dr. Trevor Berry explore the evolving science of low-level laser therapy (LLLT), also known as photobiomodulation (PBM), and the remarkable ways light interacts with human physiology. The conversation begins with an examination of laser therapy research, FDA clearances, and why understanding the differences between medical devices matters. The discussion then moves into the fascinating field of optogenetics, where researchers have demonstrated how genetically introduced light-sensitive proteins can be used to control the activity of specific neurons. Chad and Trevor also explore the relationship between light and mitochondrial function, the emerging research surrounding neuroplasticity and brain-derived neurotrophic factor (BDNF), and the potential role of photobiomodulation in supporting brain health. Beyond the laboratory, they discuss the importance of movement, exercise, nutrition, and the brain–gut connection, including a clinical experience that illustrates why nervous system function deserves attention as part of a comprehensive approach to health. In this episode, you'll discover: Why research quality and FDA-cleared indications matter when evaluating laser therapy devices. The difference between FDA clearance based on substantial equivalence and evidence from device-specific clinical trials. How light-sensitive cellular receptors interact with different wavelengths. What optogenetics reveals about the relationship between light and nervous system activity. Why mitochondria and cytochrome c oxidase are important in photobiomodulation research. How scientists are studying light therapy in relation to neuroplasticity, neurogenesis, and BDNF. Why exercise and movement remain essential components of brain health. How the brain–gut axis and autonomic nervous system influence digestive function. Why nutrition, supplementation, and nervous system rehabilitation may need to work together. How mindset and expectations can influence measurable physiological responses. The bigger picture One of the central themes of this episode is that health is not simply a matter of supplying the body with the right chemicals or nutrients. The body also depends on energy production, neural communication, movement, and appropriate environmental signals. Photobiomodulation is an emerging area of research investigating how targeted light exposure may influence some of these processes. Join Dr. Woolner and Dr. Berry for an engaging discussion of the science, clinical possibilities, and unanswered questions surrounding light-based therapies.
