A group for professional clinicians -- either those already using the LENS, or those licensed clinicians interested in the possibility of using the LENS -- sharing questions, comments, ideas, research, tips, and suggestions about the development and use of the Low Energy Neurofeedback System and photonic stimulation technologies. Expertise is most demonstrated and helpful by first asking questions before rendering opinion and suggestions.

Fervent exchanges of opinion, i.e., arguments, as well as commercial announcements not related directly to the LENS and photonic stimulation technologies and training therein, are grounds for suspension from the list until there is fresh agreement to avoid these behaviors.
