We report observations of cardiac-evoked long-range zero quantum coherence
(ceZQC) in human brain tissue which were not accompanied by an alternation of
short-range quantum coherence. For every cardiac pulsation, ceZQC emerged over
the entire brain tissue for a period of 270 ± 180 ms. We observed this
quantum effect in 40 human volunteers, if and only if they were awake. This
link to conscious awareness suggests that the information held in the
long-range quantum phenomenon is used and manipulated in conscious-related
computation
