De la tratarea depresiei p\u00e2n\u0103 la reducerea consecin\u021belor bolii Parkinson \u0219i trezirea pacien\u021bilor afla\u021bi \u00een stare vegetativ\u0103, stimularea creierului cu ajutorul curentului electric are un poten\u021bial uria\u0219. Una dintre noile cercet\u0103ri \u0219i-a \u00eendreptat eforturile c\u0103tre oprirea declinului capacit\u0103\u021bilor cognitive, \u00eembun\u0103t\u0103\u021bind memoria \u0219i abilit\u0103\u021bile de \u00eenv\u0103\u021bare. Un experiment realizat de cercet\u0103torii de la Universitatea Boston a demonstrat o tehnic\u0103 non-invaziv\u0103 capabil\u0103 s\u0103 re\u00eentregeasc\u0103 memoria de lucru la v\u00e2rstnici de 70 de ani, astfel \u00eenc\u00e2t s\u0103 devin\u0103 comparabil\u0103 cu cea a persoanelor de 20 de ani.<\/p>\n

\u00cen multe studii de stimulare a creierului se folosesc electrozi, implanta\u021bi \u00een anumite zone ale creierului, pentru a livra impulsuri electrice. Aceast\u0103 procedur\u0103 se nume\u0219te \u201estimulare profund\u0103\u201d sau \u201edirect\u0103\u201d a creierului \u0219i are avantajele sale datorit\u0103 pozi\u021bion\u0103rii precise a efectului. Cu toate acestea, implantarea electrozilor \u00een creier este destul de nepractic\u0103 \u0219i, de asemenea, este asociat\u0103 cu anumite riscuri de inflamare sau infec\u021bie \u00een cazul nerespect\u0103rii tuturor normelor de operare.<\/p>\n

O alternativ\u0103 este stimularea indirect\u0103 printr-o metod\u0103 non-invaziv\u0103 (non-chirurgical\u0103) folosind electrozi plasa\u021bi pe scalp, ceea ce permite realizarea unor astfel de manipul\u0103ri chiar \u0219i \u00een condi\u021bii de acas\u0103. Aceast\u0103 metod\u0103 a fost utilizat\u0103 de Rob Reinhart, un neurobiolog de la Universitatea Boston, \u00een efortul de a \u00eembun\u0103t\u0103\u021bi memoria v\u00e2rstnicilor, care, \u00een general, se diminueaz\u0103 odat\u0103 cu v\u00e2rsta.<\/p>\n

Mai exact, experimentele sale s-au concentrat pe memoria de lucru, care se activeaz\u0103, de exemplu, c\u00e2nd ne amintim ce trebuie s\u0103 lu\u0103m din magazinul alimentar sau c\u00e2nd \u00eencerc\u0103m s\u0103 g\u0103sim cheile ma\u0219inii. Potrivit lui Reinhart, memoria de lucru poate \u00eencepe s\u0103 se degradeze \u00eenc\u0103 de la 30 de ani, deoarece diferite p\u0103r\u021bi ale creierului \u00eencep s\u0103-\u0219i piard\u0103 coeren\u021ba \u0219i devin mai pu\u021bin coordonate. Atunci c\u00e2nd atingem 60 sau 70 de ani, aceast\u0103 incoeren\u021b\u0103 poate conduce la o sc\u0103dere semnificativ\u0103 a func\u021biilor cognitive.<\/p>\n

Cercet\u0103torul a descoperit o modalitate de a restabili conexiunile neuronale afectate. Metoda se bazeaz\u0103 pe dou\u0103 elemente ale func\u021bion\u0103rii creierului. Primul este \u201econectarea\u201d, c\u00e2nd diferite p\u0103r\u021bi ale creierului sunt activate \u00eentr-o secven\u021b\u0103 prestabilit\u0103, ca un orchestra bine orchestrat\u0103. Al doilea este \u201esincronizarea\u201d, c\u00e2nd ritmurile mai lente, cunoscute sub numele de ritmuri theta \u0219i asociate cu hippocampul, sunt sincronizate corespunz\u0103tor. Ambele func\u021bii se degradeaz\u0103 odat\u0103 cu v\u00e2rsta \u0219i afecteaz\u0103 memoria.<\/p>\n

\"Stimularea<\/p>\n

Pentru experimentul s\u0103u, Reinhardt a implicat un grup de tineri cu v\u00e2rsta de aproximativ 20 de ani, precum \u0219i un grup de persoane \u00een v\u00e2rst\u0103 cu v\u00e2rste cuprinse \u00eentre 60 \u0219i 70 de ani. Fiecare grup a trebuit s\u0103 execute o serie de sarcini specifice, care implicau vizionarea unei imagini, o pauz\u0103, vizionarea unei a doua imagini \u0219i apoi, din memorie, s\u0103 identifice diferen\u021bele dintre ele.<\/p>\n

Nu este surprinz\u0103tor c\u0103 grupul de tineri a performat mult mai bine dec\u00e2t grupul mai \u00een v\u00e2rst\u0103. Dar apoi, Reinhardt a aplicat o stimulare u\u0219oar\u0103 a cortexului cerebral \u00een r\u00e2ndul persoanelor \u00een v\u00e2rst\u0103 timp de 25 de minute, cu impulsuri setate pe contururile nervoase ale fiec\u0103rui pacient \u00een func\u021bie de zona cortexului responsabil\u0103 pentru memoria de lucru. Dup\u0103 aceasta, grupurile au continuat s\u0103 \u00eendeplineasc\u0103 sarcinile, iar diferen\u021ba \u00een precizia realiz\u0103rii sarcinilor \u00eentre ele a disp\u0103rut. Efectul a durat cel pu\u021bin 50 de minute dup\u0103 stimulare. Mai mult, Reinhardt a descoperit c\u0103 poate \u00eembun\u0103t\u0103\u021bi func\u021bia memoriei chiar \u0219i la tinerii care au avut dificult\u0103\u021bi \u00een sarcini.<\/p>\n

\u201eAm descoperit c\u0103 subiec\u021bii de 20 de ani, care au avut dificult\u0103\u021bi \u00een \u00eendeplinirea sarcinilor, au putut de asemenea s\u0103 beneficieze de aceea\u0219i stimulare\u201d, spune Reinhart. \u201eAm reu\u0219it s\u0103 \u00eembun\u0103t\u0103\u021bim memoria lor de lucru, chiar dac\u0103 nu au avut 60 sau 70 de ani.\u201d<\/p>\n

Reinhardt sper\u0103 s\u0103 continue studiul modului \u00een care stimularea creierului poate \u00eembun\u0103t\u0103\u021bi func\u021bionarea creierului uman, \u00een special pentru cei care sufer\u0103 de boala Alzheimer.<\/p>\n

\u201eAceasta deschide noi oportunit\u0103\u021bi pentru cercetare \u0219i tratament\u201d, spune el. \u201e\u0218i suntem foarte bucuro\u0219i \u00een leg\u0103tur\u0103 cu acest lucru.\u201d<\/p>\n

Studiul a fost publicat \u00een jurnalul Nature Neuroscience.<\/p>\n
