Although Psychedelics Encyclopedia (1992) suggests that a prototype for such a machine was attempted but never reached a functioning state,” the original 1966 article features data gathered from tests run: “The first session was run as a control period, without drugs. The set was to meditate in silence. The second recording was made three hours after the ingestion of 250 gamma of LSD. Both sessions were run in a very small room; the subject lay on a mattress on the floot, hands resting easily on the two keyboards of the E.T. The console and recorder were ;in an adjacent room. The room was lit by one candle; actually the subject kept his eyes closed throughout both sessions” (83).
In an article from 2006, Marko comments that "While insightful as to the timing of the various phases of the experience(e.g. onset, encounter, comedown), the results of these experiments only provide a real-time subjective assessment of the experience. This experimental methodology only provides a more objective understanding to the course of events during DMT inebriation."
