In this co-hosted program, Dr. Hardt shares more on the history of brain wave research. Particularly in relation to just how important it is to get accurate brain wave readings which are not confused by various interfering conditions, or any artifacts of the measuring process itself. Certainly an important part of his own contribution to the field, has been the various ways he himself has helped to inventively improve accurate instrumentation. Inasmuch as the more effective the feedback reading one is able to provide, the more effective any brain wave training program is going to be.
