Stresul nu influen\u021beaz\u0103 doar ceea ce sim\u021bim, ci \u0219i ceea ce ne amintim. Un studiu realizat de cercet\u0103torii de la Universitatea Yale arat\u0103 c\u0103 hormonul cortizol poate \u00eent\u0103ri amintirile asociate experien\u021belor intense din punct de vedere emo\u021bional, potrivit ScienceDaily<\/a>.<\/p>\n

Cercetarea, publicat\u0103 \u00een revista Science Advances, explic\u0103 modul \u00een care cortizolul modific\u0103 activitatea \u0219i comunicarea dintre re\u021belele cerebrale implicate \u00een procesarea emo\u021biilor \u0219i formarea amintirilor.<\/p>\n

\u201eCu to\u021bii experiment\u0103m stresul, iar laboratorul meu este interesat s\u0103 \u00een\u021beleag\u0103 cum poate fi acesta benefic\u201d, a declarat Elizabeth Goldfarb, profesoar\u0103 de psihiatrie la Yale School of Medicine \u0219i autoare a studiului.<\/p>\n

Cum influen\u021beaz\u0103 stresul memoria<\/h2>\n

Pentru a analiza efectele cortizolului asupra creierului, cercet\u0103torii au realizat un experiment \u00een care participan\u021bii au primit fie hidrocortizon, o form\u0103 de cortizol, fie un placebo.<\/p>\n

Ulterior, ace\u0219tia au privit o serie de imagini \u00een timp ce activitatea cerebral\u0103 le era monitorizat\u0103 prin rezonan\u021b\u0103 magnetic\u0103 func\u021bional\u0103.<\/p>\n

Participan\u021bii au evaluat intensitatea emo\u021bional\u0103 a imaginilor, iar a doua zi au fost testa\u021bi pentru a determina c\u00e2t de bine \u0219i le aminteau.<\/p>\n

Fiecare persoan\u0103 a participat de dou\u0103 ori la experiment, o dat\u0103 dup\u0103 administrarea hidrocortizonului \u0219i o dat\u0103 dup\u0103 administrarea placebo.<\/p>\n

De ce unele amintiri devin mai puternice<\/h2>\n

Rezultatele au ar\u0103tat c\u0103 hormonul cortizol \u00eembun\u0103t\u0103\u021be\u0219te memorarea experien\u021belor cu o semnifica\u021bie emo\u021bional\u0103 puternic\u0103.<\/p>\n

Cercet\u0103torii au descoperit c\u0103 acesta modific\u0103 activitatea re\u021belelor cerebrale responsabile de procesarea emo\u021biilor \u0219i de formarea amintirilor.<\/p>\n

\u00cen re\u021belele asociate emo\u021biilor, cortizolul a determinat modele de activitate mai constante \u0219i o implicare mai intens\u0103. \u00cen cele responsabile de memorie, hormonul a favorizat procesarea informa\u021biilor cu \u00eenc\u0103rc\u0103tur\u0103 emo\u021bional\u0103.<\/p>\n

De asemenea, cortizolul a \u00eembun\u0103t\u0103\u021bit coordonarea dintre cele dou\u0103 tipuri de re\u021bele, ceea ce ar putea explica de ce anumite experien\u021be sunt mai greu de uitat.<\/p>\n

Stresul ar putea avea \u0219i un rol benefic \u00een \u00eenv\u0103\u021bare<\/h2>\n

Cercet\u0103torii subliniaz\u0103 c\u0103 stresul nu \u00eembun\u0103t\u0103\u021be\u0219te memoria \u00een mod general, ci favorizeaz\u0103 \u00een special p\u0103strarea experien\u021belor considerate intense sau importante.<\/p>\n

\u201eR\u0103spunsurile la stres sunt fundamental adaptative \u0219i v\u0103 pot ajuta s\u0103 forma\u021bi amintiri puternice, dar acest lucru este specific experien\u021belor pe care le considera\u021bi intense sau semnificative din punct de vedere emo\u021bional\u201d, a explicat Goldfarb.<\/p>\n

Potrivit cercet\u0103toarei, asocierea informa\u021biilor noi cu elemente interesante sau cu emo\u021bii puternice ar putea facilita \u00eenv\u0103\u021barea, inclusiv \u00een situa\u021bii stresante.<\/p>\n

Descoperirea sugereaz\u0103 c\u0103 stresul nu perturb\u0103 \u00eentotdeauna memoria, ci poate ajuta creierul s\u0103 prioritizeze \u0219i s\u0103 p\u0103streze experien\u021bele cu o semnifica\u021bie deosebit\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
