Just wondering if there is any app or combination of apps that will compute the theta/beta ratio. Sorry I can’t be more technical than that, I’m a non-specialist, but my understanding is that this is a metric of interest with regard to measuring attentional control and (perhaps) diagnosing ADD
Use muse monitor to record a session, export to CVS.
It’s just a math problem then if I understand what you asked.
There isn’t an app that does this in real time as far as I know.
