Experiment with EEG to explore the algorithms behind focus/attention.

For our first experiment, I was thinking about EEG.

Here is specifically what I want to test: I hear a rumor that focus / attention is measurable by looking at the ratio of the power spectrum densities of beta to alpha. Or alpha to beta; whatever. And I'm guessing there's a moving average or two in there somewhere. I'm curious - if a small group of us get together and measure ourselves relaxing, eyes closed, doing deep breathing and then transitioning to intensely focusing (we can come up with some standardized task), what would those alpha psd : beta psd ratios look like? Are there additional signal processing or algorithmic steps required to derive a useful measure for focus?

My cell:[masked] 8566.

Street parking is fine.

This time around, I'm going to cover the cost of disposable electrodes (there really aren't that many of us).

I'm going to order a pizza or two. If you want pizza, let me know so I can order the right amount.

We may start a Google Doc ahead of time for knowledge share and prep beforehand. If so I will send out a group email before the meetup.

Finally, Sky Christopherson is making a documentary film about QS. He may attend this meetup and film people (only those who wish to be filmed, obviously) as b-roll for his movie (he's going for the grass-roots qs & experimentation community feel). You can still attend even if you do not wish to be filmed - not a problem. If you would like to potentially be included in the documentary, let me know.

I'm capping this at around 15 people initially; I think that's a good size to shoot for. About ten people in addition to the four or so plus myself who are going for sure.

    I had a good time at this. Sorry if this was posted already - did we ever end up comparing beta to alpha?

    If we do this again, I’ll definitely chip in some :)

    I would love to attend this, but I have to work during business hours and couldn't get there until 6:45pm best case. Hope to catch you next time.

We just grab a coffee and speak French. Some people have been coming every week for months... it creates a kind of warmth to the group.
