„Na 70 procent lid\u00ed tvrd\u00ed, \u017ee ve snu vid\u011bli ud\u00e1losti, kter\u00e9 se pak tak\u00e9 skute\u010dn\u011b staly,“ \u0159\u00edk\u00e1 neurolo\u017eka Isabelle Arnulfov\u00e1. Nelze tedy \u0159\u00edci, \u017ee v\u017edy \u0161lo o pouhou shodu okolnost\u00ed.<\/strong><\/p>\n

Aby probl\u00e9m objasnila, vybrala si expertka za pokusn\u00e9 „kr\u00e1l\u00edky“ 2324 student\u016f, kte\u0159\u00ed se p\u0159ipravovali ke zkou\u0161k\u00e1m na pa\u0159\u00ed\u017esk\u00e9 fakult\u011b Pierra a Marie Curieov\u00fdch, kde vyu\u010duje. Jej\u00ed t\u00fdm se jich v prvn\u00ed den zkou\u0161ek dot\u00e1zal, zda se jim p\u0159ede\u0161lou noc zd\u00e1lo o zkou\u0161k\u00e1ch a zda ve snu zkou\u0161ku ud\u011blali \u010di nikoli. Pak v\u011bdci \u010dekali na skute\u010dn\u00e9 v\u00fdsledky zkou\u0161ek.<\/p>\n

A z\u00e1v\u011br? No\u010dn\u00ed sc\u00e9n\u00e1\u0159e, kter\u00e9 byly v\u011bt\u0161inou pesimistick\u00e9, nem\u011bly z hlediska p\u0159edv\u00edd\u00e1n\u00ed v\u011bc\u00ed \u017e\u00e1dnou hodnotu. „Studenti, kte\u0159\u00ed ve snu zkou\u0161ky neud\u011blali, u nich ve skute\u010dnosti nepropadli,“ konstatovala profesorka Arnulfov\u00e1.<\/p>\n

Zaj\u00edmav\u00e9 v\u0161ak bylo, \u017ee v\u0161ech prvn\u00edch deset p\u0159ijat\u00fdch m\u011blo no\u010dn\u00ed m\u016fry, kdy se jim zd\u00e1lo, \u017ee p\u0159i\u0161li na zkou\u0161ky pozd\u011b nebo odevzdali pr\u00e1zdn\u00fd list pap\u00edru. Obecn\u011b se d\u00e1 \u0159\u00edci, \u017ee \u010d\u00edm v\u00edce studenti o zkou\u0161k\u00e1ch snili, t\u00edm byly jejich zn\u00e1mky lep\u0161\u00ed. Jakoby se mozek v noci cvi\u010dil a v p\u0159edv\u00edd\u00e1n\u00ed zkou\u0161ek redukoval strach z nezn\u00e1m\u00e9ho.<\/p>\n

A jin\u00e9 vysv\u011btlen\u00ed? „N\u00e1\u0161 mozek produkuje tis\u00edce sn\u016f, na kter\u00e9 se nepamatujeme. Kdy\u017e pak nastane skute\u010dn\u00e1 ud\u00e1lost, vzpomeneme si na sen, kter\u00fd se k n\u00ed vztahoval, a tak m\u00e1me dojem, \u017ee jsme ji p\u0159edv\u00eddali,“ \u0159\u00edk\u00e1 profesorka Arnulfov\u00e1, kterou citoval francouzsk\u00fd t\u00fdden\u00edk L’Express.<\/p>\n

V\u011bdci zjistili, jak dos\u00e1hnout toho, aby lid\u00e9 z\u016fstali ve snu p\u0159i v\u011bdom\u00ed: je t\u0159eba stimulovat jejich mozek slab\u00fdm elektrick\u00fdm proudem.<\/p>\n

Jde o velk\u00fd objev v tajemn\u00e9 sf\u00e9\u0159e sn\u016f. \u0158\u00edk\u00e1 se tomu „pr\u016fzra\u010dn\u00fd sen“. Ve sp\u00e1nku si uv\u011bdomujete, \u017ee sn\u00edte a ovliv\u0148ujete b\u011bh ud\u00e1lost\u00ed. Proberete se z o\u0161kliv\u00e9ho snu, pro\u017e\u00edv\u00e1te \u00fa\u017easn\u00e1 dobrodru\u017estv\u00ed, vyhnete se smrti. Dos\u00e1hnout tohoto v\u011bdom\u00ed vy\u017eaduje \u010dasto dlouhodobou pr\u00e1ci. V\u011bdci tuto problematiku zkoumali od 19. stolet\u00ed, ale teprve ned\u00e1vn\u00e1 studie zve\u0159ejn\u011bn\u00e1 v \u010dasopise Nature Neuroscience znamen\u00e1 jist\u00fd pr\u016flom.<\/p>\n

N\u011bme\u010dt\u00ed v\u011bdci objevili, \u017ee stimulace pomoc\u00ed elektrick\u00e9ho proudu vyvol\u00e1vaj\u00ed tento \u00fa\u010dinek b\u011bhem f\u00e1ze sp\u00e1nku ozna\u010dovan\u00e9 jako paradoxn\u00ed, kdy vznikaj\u00ed sny, na n\u011b\u017e si vzpom\u00edn\u00e1me.
\nExpertka na sp\u00e1nek, psycholo\u017eka Ursula Vossov\u00e1 z Goethovy univerzity ve Frankfurtu nad Mohanem a jej\u00ed t\u00fdm uskute\u010dnili s\u00e9rii pokus\u016f se 27 mu\u017ei a \u017eenami. Po t\u0159ech minut\u00e1ch nep\u0159eru\u0161en\u00e9ho paradoxn\u00edho sp\u00e1nku vyslali v\u011bdci skrz lebku slab\u00fd elektrick\u00fd proud do front\u00e1ln\u00ed a tempor\u00e1ln\u00ed z\u00f3ny mozku. Jde o bezbolestnou proceduru. Kr\u00e1tce pot\u00e9 pacienty probudili a t\u00e1zali se jich na jejich sny.<\/p>\n

Kdy\u017e v\u011bdci pou\u017eili frekvenci 25 nebo 40 Hz, v\u011bt\u0161ina pokusn\u00fdch osob uvedla, \u017ee se vid\u011bly jakoby zven\u010d\u00ed, \u017ee byly jak\u00fdmisi div\u00e1ky, kte\u0159\u00ed se na sebe d\u00edvaj\u00ed na obrazovce. Rovn\u011b\u017e \u010dasto \u0159\u00edkali, \u017ee si uv\u011bdomovali, \u017ee sn\u00ed.
\nV\u011bdci hodlaj\u00ed tuto techniku vyu\u017e\u00edvat pro terapeutick\u00e9 \u00fa\u010dely.
