Great article, Michael. The approval of devices like these does an end run around an inconvenient truth of neurobiology: The entire idea of functional localization neutoanatomy is highly suspect to begin with, so it would seem impossible to even speculate reasonably about what the outcome would be of simply attaching an electrode to the front of someone’s head. This intervention would appear to be absolute crackpottery of the most brazen and malignant kind. This article was from 2002, but I do not think much has changed since then. https://www.ece.uvic.ca/~bctill/papers/learning/Brett_etal_2002.pdf “Current methods of matching different brains cannot eliminate differences in functional areas across individuals, because the positions of these areas are not well predicted by gross anatomical landmarks in many regions.” I admire your stats as a no-hitter for medication referrals. (I’ve only made one since I’ve been licensed, with a patient who absolutely insisted on it, though I’m hopeful the patient will not fill the prescription. They have not yet.) That is an incredible accomplishment you should be proud of.
