Transcranial photobiomodulation is one of the most exciting areas in red light therapy right now—especially for brain health, cognitive performance, and neurological conditions.
In this episode, I sit down with Austin from Vielight at PBM 2024 in London to explore how their brain-focused light therapy devices work. We discuss why targeted stimulation of specific brain networks matters, the role of intranasal light therapy, and how their fourth-generation headset has evolved.
Austin also explains how their devices are designed to stimulate regions associated with the default mode network, why proximity and power density matter when delivering light to the brain, and why combining transcranial and intranasal photobiomodulation may produce stronger effects than external light alone.
Show Notes
In this conversation with Austin from Vielight, we discuss how photobiomodulation devices designed specifically for the brain differ from typical red light panels.
Austin explains the science behind targeting specific brain regions such as the default mode network, why precise dosing and proximity to the scalp matter, and how intranasal light therapy can reach deeper areas of the brain.
We also explore the new fourth-generation Vielight headset, improvements in comfort and design, and how researchers and biohackers are using customizable protocols for cognitive performance and neurological support.
Key Topics
Targeting the Brain’s Default Mode Network
Vielight devices are designed to stimulate specific areas of the brain associated with the default mode network. This network plays a role in subconscious processing and is often disrupted in conditions such as Alzheimer’s disease. Targeted stimulation may help improve connectivity in these regions.
Why Brain Devices Differ from Red Light Panels
Austin explains that standing in front of a panel may deliver light to the head, but the distance dramatically reduces how much energy reaches the brain. Their headset places LEDs directly against the scalp to maximize light delivery and reduce energy loss.
The Role of Intranasal Photobiomodulation
One of Vielight’s patented technologies involves intranasal light therapy. Because the nasal cavity provides a pathway closer to deeper brain structures, intranasal stimulation may complement transcranial light by reaching areas that scalp-based LEDs cannot.
Multiple Wavelength Options
The company offers several intranasal wavelengths including blue (470 nm), red (633 nm and 655 nm), and near-infrared (810 nm). Each wavelength is used for different applications, such as antimicrobial support, systemic circulation, or brain stimulation.
Targeted vs Full-Brain Stimulation
Austin explains that stimulating the entire brain may not always be ideal. Targeted stimulation allows researchers to focus on specific neural networks without overwhelming the brain with excessive stimulation or reactive oxygen species.
Fourth-Generation Vielight Headset Improvements
The newest version of the headset improves comfort, flexibility, and fit while also adding cerebellum stimulation. This allows users to stimulate additional brain regions without needing a second device.
Customizable Protocols for Biohackers and Practitioners
The upcoming Neuro Pro device allows individual LEDs to be controlled independently. This means specific brain networks—such as the salience network or default mode network—can be stimulated using custom protocols.
