Figure 1 Vielight Neuro RX Gamma


The Vielight Neuro devices (Vielight Neuro RX Gamma and Neuro Alpha R) are intended to deliver NIR PBM to the brain, transcranially and intranasally (Figure 1). The devices utilize identical hardware and only differ in the frequency of PBM being delivered. The Neuro RX Gamma delivers a fixed frequency of 40Hz PBM while the Neuro Alpha R delivers a personalized frequency ranging from 8-13Hz.

(A) Components of the device – the nasal applicator and headset with built-in controller are identified.

(B) The device is shown on a mannequin head to demonstrate the placement of the six LEDs.
