The Neuro Duo 4 is a photobiomodulation device designed to deliver two specific brainwave-related frequencies: 40Hz gamma and 10Hz alpha. These frequencies are selected because research suggests they may influence different aspects of cognitive and neurological function.

40Hz Gamma Mode

The gamma setting emits pulsed near-infrared light at 40Hz, a frequency associated in scientific literature with attention, working memory, and certain cognitive processing patterns. Some studies in early neurostimulation research explore 40Hz for its potential connection to cognitive support and neural network activity.

10Hz Alpha Mode

The alpha setting emits light pulsed at 10Hz, a frequency commonly linked with calmness, relaxed wakefulness, and the transition toward sleep states. Alpha rhythms naturally increase during meditative or relaxed mental states, and this mode is included for users who want a gentler stimulation pattern.

Purpose of Having Two Modes

By offering both a gamma and an alpha frequency, the Neuro Duo 4 allows users to engage with two distinct patterns of neural activity:

• Gamma for cognitive engagement and mental activation

• Alpha for relaxation and reduced arousal

This makes the Duo 4 suitable for individuals who want flexibility depending on the time of day or the mental state they wish to support.

General Notes

• The device uses non-invasive near-infrared LEDs.

• Its purpose is to supplement wellness routines; it is not a medical treatment or diagnostic tool.

• Effects can vary depending on the user, frequency of use, and individual neurobiology.
