Using frequencies to balance brain function has been well-researched for decades using Cranial Electro Stimulation (CES) devices similar to Bob Beck’s Brain Tuner.
Research at Boston University is using specific alternating current or frequencies to control brain function in two fundamental brain areas—the medial frontal cortex and the lateral prefrontal cortex. The research suggests that the use of high-definition transcranial alternating current stimulation (HD-tACS) shows promise to replace prescription drugs with fewer potential side-effects.
CES is approved by the FDA for anxiety, depression and insomnia, allowing these conditions to be handled without the use of drugs. CES uses frequencies designed to simply bring brain chemicals into balance. This new research uses frequencies to specifically change the executive function of the brain.
It would seem that both technologies have the potential to improve the ability to learn more readily.
More details about the research are given in a media release from Boston University titled
