De har brugt et \u201cZero-G\u201d-fly til at flyve h\u00f8jt op i luften og derefter styrtdykke nedad, s\u00e5 det for passagererne f\u00f8les, som om de er v\u00e6gtl\u00f8se! En gruppe frivillige tilb\u00f8d at lade deres hjerner blive unders\u00f8gt under disse perioder med v\u00e6gtl\u00f8shed for at se, hvordan de blev p\u00e5virket. Ved hj\u00e6lp af virtual reality-briller skulle de udf\u00f8re opgaver, s\u00e5som at l\u00e6re, huske og navigere i nye omgivelser.
