Initial Human Studies with 40 Hz Gamma Show Promise

Preliminary Human Studies Measuring the Brain's Immune System

Posterior Cingulate Cortex and Precuneus represent a critical network of interacting regions of the brain for recalling episodic (specific) memories.

After 8 weeks of daily light and sound sessions with 40 Hz, researchers observed a significant increase in connectivity between the Posterior Cingualator Cortex and Precuneus 

 Cytokines are a category of small proteins that are critical for healthy immune responses to infection and inflammation.

 Cytokines found in cerebral spinal fluid are a key measure of immune response. At 8 weeks the data showed that the immune system is being engaged in humans with 40Hz  Gamma flicker.
