Ocitneme se na nezn\u00e1m\u00e9m m\u00edst\u011b – v dom\u011b nebo na ulici a najednou m\u00e1me jistotu, \u017ee jsme tu u\u017e jednou kdysi byli.\u00a0<\/strong><\/p>\n

St\u00e1l tu tento n\u00e1bytek a rostly tu tyto stromy. Byli tu i ti sam\u00ed lid\u00e9. A mluvili na to sam\u00e9 t\u00e9ma jako kdysi.<\/p>\n

V Marseille<\/em> prob\u011bhla v roce 2011 prvn\u00ed konference v\u011bnovan\u00e1 tomuto fenom\u00e9nu (1)<\/p>\n

Deja vu<\/em> – to je iluze u\u017e vid\u011bn\u00e9ho. Podle statistik jej za\u017eije asi 60 procent lid\u00ed alespo\u0148 jednou v \u017eivot\u011b.<\/p>\n

Zd\u00e1 se, \u017ee se sou\u010dasnost setk\u00e1v\u00e1 s minulost\u00ed. Ale v\u011bdom\u00ed se zdr\u00e1h\u00e1 tomu v\u011b\u0159it. V\u017edy\u0165 v\u00edme, \u017ee ani jeden moment historie nem\u016f\u017eeme pro\u017e\u00edt dvakr\u00e1t.<\/p>\n

Od roku 1990 se deja vu<\/em> stalo v\u00fdzkumn\u00fdm t\u00e9matem modern\u00edch v\u011bd, zkoumaj\u00edc\u00edch mozek.<\/p>\n

V\u011bdci se 9.- 12. kv\u011btna 2012 dokonce se\u0161li v Marseille na prvn\u00ed v\u011bdeck\u00e9 konferenci v\u011bnovan\u00e9 v\u00fdhradn\u011b tomuto jevu.<\/p>\n

Podle odborn\u00edk\u016f, fenom\u00e9n byl pozorov\u00e1n u pacient\u016f, trp\u00edc\u00edch epilepsi\u00ed na sp\u00e1nkov\u00fdch laloc\u00edch.<\/p>\n

Ti um\u00ed dokonale popsat tento divn\u00fd pocit, doprov\u00e1zen\u00fd nep\u0159\u00edjemn\u00fdmi pocity v \u017ealudku, n\u011bkdy i ztrat\u00ed v\u011bdom\u00ed.<\/p>\n

Jak se \u010dasto st\u00e1v\u00e1 v neurologii, a\u017e patologie n\u00e1m umo\u017e\u0148uje pochopit norm\u00e1ln\u00ed fungov\u00e1n\u00ed mozku.<\/p>\n

P\u0159i studiu mozk\u016f epileptik\u016f, do\u0161li v\u011bdci k n\u00e1sleduj\u00edc\u00edmu z\u00e1v\u011bru: v\u0161e se d\u011bje takov\u00fdm zp\u016fsobem, \u017ee k tvorb\u011b vzpom\u00ednek doch\u00e1z\u00ed ne po vn\u00edm\u00e1n\u00ed ud\u00e1losti, ale z\u00e1rove\u0148 s n\u00edm.<\/p>\n

Sou\u010dasn\u00fd moment je sou\u010dasn\u011b vn\u00edm\u00e1n jako vzpom\u00ednka a st\u00e1v\u00e1 se pam\u011bt\u00ed.<\/p>\n

Vysv\u011btlen\u00ed jevu deja vu jako nadp\u0159irozen\u00e9ho \u00fakazu, spojen\u00e9ho s existenc\u00ed p\u0159edchoz\u00edch \u017eivot\u016f p\u0159i reinkarnaci, poch\u00e1z\u00ed z \u00a8konce XIX. stolet\u00ed, neodpov\u00edd\u00e1 skute\u010dnosti.<\/p>\n

V\u011bdci se sna\u017eili zjistit, zda existuj\u00ed rozd\u00edly mezi t\u011bmi lidmi, kte\u0159\u00ed za\u017eili deja vu, a t\u011bmi, kte\u0159\u00ed se s n\u00edm nesetkali. A zjistili: fenom\u00e9n d\u00e9j\u00e0 vu je spojen s individu\u00e1ln\u00edmi anatomick\u00fdmi zvl\u00e1\u0161tnostmi lidsk\u00e9ho mozku.<\/p>\n

Experimentu se z\u00fa\u010dastnilo 113 zdrav\u00fdch dobrovoln\u00edk\u016f.<\/p>\n

Ale u n\u011bkter\u00fdch k pocitu deja vu doch\u00e1zelo \u010dast\u011bji, zat\u00edmco druz\u00ed o tomto jevu v\u016fbec nev\u011bd\u011bli.<\/p>\n

U v\u0161ech byl zkoum\u00e1n mozek pomoc\u00ed magnetick\u00e9 rezonance a novou citlivou metodou, analyzuj\u00edc\u00ed morfologii mozku. Toto zkoum\u00e1n\u00ed zjistilo, \u017ee pro vznik deja vu, je za prv\u00e9 na vin\u011b hippocampus. Za druh\u00e9, pe\u010dliv\u011bj\u0161\u00ed anal\u00fdza odhalila d\u016fle\u017eitou zvl\u00e1\u0161tnost u t\u011bch lid\u00ed, kte\u0159\u00ed si \u010dast\u011bji n\u011bco „pamatovali“ z p\u0159edchoz\u00edch \u017eivot\u016f.<\/p>\n

V jejich kortik\u00e1ln\u00ed – hlavn\u011b mesiotempor\u00e1ln\u00ed a subkortik\u00e1ln\u00ed oblasti byla v\u00fdrazn\u011b men\u0161\u00ed \u0161ed\u00e1 hmota, ne\u017e u t\u011bch, kte\u0159\u00ed nikdy takov\u00fd z\u00e1\u017eitek nem\u011bli,\u201c \u0159\u00edk\u00e1 jeden z vedouc\u00edch autor\u016f studie Milan Br\u00e1zdil. \u201eProto, z\u00e1kladem deja vu jsou neurofyziologick\u00e9 abnormality. Vznikaj\u00ed v d\u011btstv\u00ed p\u0159i tvorb\u011b mozku.<\/p>\n

V d\u016fsledku selh\u00e1v\u00e1 ta oblast mozku, kde je \u0161ed\u00e1 hmota p\u0159ipojena k hippocampu, a je nedostate\u010dn\u011b vyvinuta.<\/p>\n

Nedostatek \u0161ed\u00e9 hmoty zp\u016fsobuje to, \u017ee hipokamp<\/em> nen\u00ed dob\u0159e ovladateln\u00fd. A tak ve zvl\u00e1\u0161tn\u00edch okam\u017eic\u00edch, obvykle b\u011bhem \u00fanavy a stresu, se st\u00e1v\u00e1 p\u0159\u00edli\u0161 aktivn\u00edm, a tak vznikaj\u00ed vzpom\u00ednky na to, co nikdy nebylo.<\/p>\n
