    profound spiritual aspects during a neardeath experience (NDE). These can include venturing

    through a dark tunnel, seeing otherworldly visions of the afterlife, encountering deceased

    relativesandfriends,andsensingthepresenceofdivinebeings,amongothers.13Butperhapsone

    of themost interestingaspects fromaparapsychological researchperspective is the sense that

    result of complex physiological processes occurring in the brain. If some NDE patients are

    apparently able to perceive and accurately recall events at timeswhen their brain function is

    either declining or gone, then thismay be suggestive of some aspect of conscious awareness

    extendingbeyondthebrain,whichsomemightinterpretasbeingsuggestiveofsurvival.Thisraises

    the question: Can NDEs of this type possibly shed some light on the nature of conscious

    experience?

    SuchaquestionwasposedbyphysicianSamParnia inanarticlepublished inthejournal

    Medical Hypotheses in 2007, in light of the results from four separate survey studies that

    examinedNDEs inhospitalpatientswhohadsurvivedcardiacarrest.10

    Parniawasacoauthorof

    thefirststudy,whichlookedatNDEsamongcardiacsurvivorsadmittedtoSouthamptonGeneral

    Hospital in theUKover aoneyearperiod.11

    Of the63 survivors, 11.1% claimed tohavebeen

    aware of themoment that they had been unconscious,with themajority of them describing

    features characteristic of NDEs. Apart from the amount of oxygen they received during their

    cardiac episode, these surviving patients did not significantly differ in vital signs or medical

    conditionfromcardiacpatientswhodidnotreportanNDE.

    Appearing in the prominent medical journal The Lancet, the second study by Dutch

    cardiologistPimvanLommelandcolleagueshadsurveyed344cardiacarrestpatients from ten

    hospitalsintheNetherlandsintheyearsbetween1988and1992.12

    Eighteenpercenthadreported

    anNDE,theoccurrenceofwhichwassignificantlymorecommonforyoungerpatients(under60

    years of age) than for older patients. Similar to the first study, NDE patients did not differ

    medicallyfromnonNDEpatientsintermsofthetypeofcardiactreatmenttheyreceived,suchas

    medication,assistedbreathing,CPR,anddefibrillation(i.e.,electricshockoftheheart).

    PsychiatristBruceGreysonoftheUniversityofVirginiasDivisionofPerceptualStudieshad

    reported the third study,which looked at 1,595patients admitted to theUniversityHospitals

    cardiac careunitover twoandahalfyears.13

    About7%of thesepatientshad sufferedcardiac

    arrest,andofthese,10% reportedanNDE. Incontrast,only1%ofpatientswithotherkindsof

    cardiacproblems

    reported

    an

    NDE.

    Greyson

    also

    found

    that

    NDEs

    were

    significantly

    common

    amongyoungerpatients,andNDEpatientswere significantlymore likely tohavehadprevious

    paranormal experiences. They also did not differ from nonNDE patients in terms of medical

    condition/diagnosis,socialstatus,andotherdemographics.

    ThefourthstudywasconductedbyresearchnurseJanetSchwaningerandhercolleagues

    at the BarnesJewish Hospital of the Washington University School of Medicine in St. Louis,

    Missouri.14

    Allpatientswho suffered cardiacarrestat thehospital fromApril1991 toFebruary

    1994were identified,andofthe30patientswhowereabletobe interviewed,23%hadhadan

    NDE.

    Collectively,thesefourstudiessuggestthatNDEsoccurinlessthanaquarter(1023%)of

    cardiac

    patients,

    that

    patients

    who

    have

    NDEs

    tend

    to

    be

    younger,

    and

    that

    there

    isnt

    anything

    thatmedicallyorsociallydistinguishesacardiacpatienthavinganNDEfromothercardiacpatients

    whodonthaveone.

    Parnia argues that NDE cases which seem to involve patient awareness and OBElike

    aspectsconstituteaproblemforscienceandmedicinethatshouldbestudiedfurtherinorderto

    exploretheimplicationsthesecasesmayhaveforconsciousness.10

    Thisargumentmaybefurther

    supplementedbyfindingsfromotherstudieswhichsuggestthatsuchNDEcasesmaynotbeeasily

    explainedaway.Forinstance,inanotherstudypublishedinTheLancet,theUniversityofVirginia

    13

    researchersfoundthatpatientswhowereclosetodeath(asdeterminedbytheirmedicalrecords)

    were significantly more likely to report enhanced mental functioning during their NDE than

    patientswhowerenotclosetodeath(butmayhavethoughttheywere).15

    Anupdatetheylater

    made to thisstudyobtained similar results, inaddition to finding thatof the130patientswho

    weredeterminedtobeclosetodeath,92%reportednormalorenhancedmentalabilityduring

    theirNDE.

    6

    Such

    findings

    again

    suggest

    the

    possibility

    of

    continuing

    mental

    awareness

    in

    NDE

    patientsatatimewhentheirbrainfunctioningispresumedtobedecreasingorgone.

    However,itisimportanttoconsiderthepossibilitythatatleastsomeinstancesofpatient

    awareness during an NDE could still be due to patients subtly gaining information through

    conventionalmeans,inspiteofappearingtobefullyunconsciousordeadatthetime.Thiswould

    of

    However,practicalissuesanddifficultyinfindinghospitalswillingandopenenoughtohostsuch

    trialshadmadeherownpreliminaryattempttoconductthemchallenging,withnoreportsofan

    NDE.20

    Morerecently,incollaborationwiththeUniversityofVirginiaresearchers,Holdenhasbeen

    able to conduct additional trials during brief moments of

    controlledcardiacarrestthatarepurposelyinducedaspart

    of the surgical implantation of small defibrillatortype

    devices insomecardiacpatients.Butagain,noneofthe52

    patientswho received thesurgery reportedanNDEduring

    their brief cardiac arrest, possibly due to the amnesia

    brought on by the sedative medication they were given

    and/ortoreassurancesthattheywouldnotbeindangerof

    dyingduringtheprocedure.21

    In addition to the relatively small number ofNDEs

    thatoccuramongcardiacpatients(basedontheestimateof

    1023%,asmentionedabove),oneotherchallengethatmaybefacedinsuchexperimentaltrials

    isthattherateofsuccessintestingOBEperceptionsduringanNDEissomewhatupintheair.A

    reviewof studies inwhichOBEperceptionswereexperimentally testedgenerally indicates that

    theevidence for suchperceptions tends tobe ratherweak,with someOBEparticipantsbeing

    successful,whileothersarenot.22

    Asone case inpoint,CharlesTart conducted six classicOBE

    studieswith

    two

    participants:

    known

    as

    Miss

    However,Tarthad lesssuccesswithMonroe,who, inspiteofhavingveryvividOBEs,wasnever

    OBE studies previously conducted by the Psychical Research Foundation in the 1970s

    Inthosestudies,OBEparticipantKeith

    Lastly,itmightbesomewhatdifficulttogeneralizeanyfindingsthatmayresultfromtest
