“But the interesting thing about a gamma spike,” explains Leslie Sherlin, “is that it always happens inside of theta oscillations. The two waves are coupled. It makes sense. Theta processes novel incoming stimuli; gamma is what happens when those stimuli snap together into new ideas. But it’s hard to do any of this on command. It takes meditators a long time to get that kind of control. This is where athletes in flow have a huge edge—their brain is already in alpha/theta. They’re holding themselves in the only state that can produce that gamma spike.”
