Very good point, Todd. Yet, there are many interesting questions that can be asked.
There are always many interesting questions that can be asked.

It is not difficult to accept the possibility that altering brain physiology or hemispheric balance can affect perception of duality/non-duality. Anything can affect the perception of duality/non-duality. It takes a lot more than one instance of this occurring for me to postulate a causal relationship, however. I am far from certain that anything is in causal relationship to the perception of duality/non-duality. This is especially true if we take a wider view, in which a change in anything is a change in everything. In such a view, the cause of any given thing is everything. Coming back to a somewhat narrower view, however, if we want to find the most likely thing that is in a causal relationship with perception of duality/non-duality, then we might be well served to look at more than one instance, and to look for common elements among those instances.
I have seen a fair number of people make the shift of perception from duality to non-duality, either while I was directly observing them, or indirectly, from their accounts of that shift. A number of people here have reported similar shifts in perception, by various different means. I have also observed this shift occur in myself a number of times, also by various different means. I cannot put my finger on a common element. Not truly. I have been able to whittle away many of my assumptions about what "causes" these shifts to occur. This leaves me with relatively simple working explanations of what is occurring. I can feel this heart of transformation but none of the words that I might put to it can possibly do it justice. The best I can do might be that there is a pause, or gap in our sense of certainty, and then we become interested in what that gap reveals. We don't turn away when the whole world that we had assumed into existence falls away and we reach the ground of transformation. Its that simple, and all of the practices, and all of the technologies are preludes to this moment. That is not to say that practices and technologies do not have their place, since the cause of anything (if such a thing as a cause can be said to exist) is everything. They just aren't the closest thing that I have been able to perceive to this shift, which can never be fixed with words or technique.
One of the potentials that the clip posted above evokes is that we might understand a physiological basis for the shift in perception from duality to non-duality. Perhaps this woman's experience is a clue to a previously not understood dynamic within our brains, an interplay of duality/non-duality, reified by the left and right hemispheres of our brains. If such a causal relationship could be established, then there would be enormous potential for various technologies, both physical and mental, to exploit this understanding and to make the shift in perception a more accessible (and controllable) reality for more people. We would have a more acceptable explanation for why we are pursuing the activities that we pursue, and perhaps we could convince more people to pursue them also.
I don't know. The potential evoked above might become actual. It might be the next expression of the all to start waking itself up while wearing the clothing of neurochemical manipulation.
The reason I say that the view I presented first holds more potential to inform our practice is that it is available right now, to anyone who cares to indulge. It can be transmitted with only a few words on a piece of paper, and it is effective. Then again, how many people actually use it? For how many people is there enough interest to really see it through, without stopping for any of the alluring potentials, inflations, bliss states, judgments, primordial drives, panic or any other of the ten thousand things?
The whole key to it is that we are already where we want to go. We can accept this or fight this. The acceptance is when this supposed shift takes place, but the shift doesn't mean anything... its all about the acceptance, no matter what arises. Until we realize that it is our great good fortune to able to accept even this,
even this. This is the destruction of technique, or the destruction of the attempt to bring technique into the heart of being. Technique still exists, and can be utilized (and developed), but the heart of being is wielding all of the techniques, and touched by none of them.
