Almostallmemoryresearchersnowagreethatourbrainsrecord—andonsomelevelremember—everythingthateverhappenstous.Manypeoplewho'venarrowlyescapedsuddendeath,suchassoldiersandmountainclimbers,havereportedthatinthefewsecondsthatseemedlefttothemastreamoflong-lostmemoriesflashedbeforethem.ThefirstexperimentalconfirmationthatthebraindoesrecordeveryexperienceinthisminutewaycamesomeyearsagofromDr.WilderPenfieldoftheMontrealNeurologicalInstitute.Hehopedtocureepileptics(癫痫病人)bystimulatingapartoftheirbrainscalledthetemporalcortex(脑的颞皮层)withamildelectriccurrent.Becausethebrainisimmunetopain,Penfieldwasabletooperatewithhispatientsfullyawake.Tohisastonishment,simplybytouchingthebrainsofsomepatientswiththetipofhiswire-thinelectrode(电极)hewasabletoevokeastonishinglypreciseandvividmemories."Iseeaguycomingthroughthefenceatthebaseballgame,"exclaimedonepatient,wheneverPenfieldtouchedtheupperpartofhislefttemporallobe(脑叶)."It'sthemiddleofthegame,andI'mbacktherewatchinghim)"Anotherwomanreportedbeingbackataconcertshehadonceattendedandcouldevenhumalongwiththeorchestrawheneverherbrainwasstimulated.
