MIT is testing light and sound to combat Alzheimer’s

In chapter 8, we discuss how different parts of the the brain communicate with each other using neural oscillations. in particular, theta waves (4-8 Hz) and alpha waves (8-13 Hz) activate in communicating with the auditory cortex, the orbitofrontal cortex and the amygdala, with theta waves being particularly active in processing emotions. Now comes research from MIT in which researchers use gamma waves (32-100 Hz) to improve memory in patients with Alzheimer's disease. Of course, it's notable that 32-100 Hz is a prime frequency range for subwoofers! Gamma rays also appear to be most active when we are alert and focused! Here's the story:, and here's the research:
