Kavli Institute of Neuroscience: "On the same wavelength — literally"

GAMMA WAVES

Why are they so important?

Because they just might explain why we get brain chatter.

Think of your brain and imagine a radio; your unrelated thoughts are like different radio broadcasts. You tune in and out of different stations — registering wildly different perceptions and memories almost simultaneously. Researchers at the Kavli Institute, part of the Norwegian University of Science and Technology, posit that this analogy describes an underlying principle of how information is handled throughout the brain. The actual mechanisms of attention are explained by the action of gamma waves.

 

Can you decrease unwanted brain chatter?  Yes. Read on here

From the article:

“Information is carried on top of gamma waves, just like songs are carried by radio waves. These “carrier waves” transmit information from one brain region to another. “We found that there are slow gamma waves and fast gamma waves coming from different brain areas, just like radio stations transmit on different frequencies,”  says University of Texas, Austin researcher Laura Colgin, whose lab is working on gamma waves in rat hippocampi.

The lower frequencies are used to transmit memories of past experiences, and the higher frequencies are used to convey what is happening where you are right now.” The cells that tune into different wavelengths work like a switch, or rather, like zapping between radio stations that are already programmed into your radio. The cells can switch back and forth between different channels several times per second. The switch allows the cells to attend to one piece at a time, sorting out what’s on your mind from what’s happening and where you are at any point in time.”
