> If such frequencies steer some kind of gate than you do have a kind of digital logic with 1 being where the brain waves cross the zero line.

What makes you think that this is the case? If someone touches you from behind do you immediately fall over dead from sensory overload? Do you react as if you where punched in the gut? Do you look over your shoulder to check who it is? Or do you fail to notice it until they break a bone? There is a significant amount of inputs where the reactions are not just zero or one but happen on a scale, your digital 1 or zero is more likely to be a 1.0 or 0.0 of a numeric type with unknown bit depth, lets go with 80bit since x87 is just the worst and completely blows the 10bit claim.
