may actually help to potentiate some of the skill acquisition that we do during the day, including meditation.
And we're doing some of that work now, which is actually you had asked earlier before we started about some novel new work that we're doing.
And that's also one of the really cool new things.
So we can dive into that.
I saw that paper too, it wasn't ours.
But yeah, super interesting, I agree.
Yeah, so just to continue with the brain oscillations, I talked about delta.
The next faster brain rhythm is theta activity, which is roughly between 5 and 7 Hz.
Theta activity is often seen during transition from wakefulness to sleep.
And it's associated with these, as you were saying earlier, these liminal states.
It's also been associated with certain kinds of meditation.
Alpha activity is roughly between 8 and 13 cycles per second or hertz.
And it's often characterized as, quote, relaxed wakefulness.
Beta activity is...
typically defined as roughly 13 to roughly 20 Hz, and it's associated with activation if there is a cognitive task that a person is engaged in, you will typically see increases in beta activity, particularly in the cortical regions that are engaged in those cognitive tasks.
And then finally there's gamma activity.
Gamma activity is especially interesting.
We see that in meditators, long-term meditators.
Gamma activity has as its peak frequency roughly 40 Hz.
It is seen in a number of contexts.
