Cercet\u0103torii au crezut c\u0103 nu p\u0103str\u0103m aceste experien\u021be pentru c\u0103 partea creierului responsabil\u0103 cu salvarea\u00a0amintirilor, hipocampul, \u00eenc\u0103 se dezvolt\u0103 \u00een adolescen\u021b\u0103 \u0219i nu poate\u00a0codifica amintirile\u00a0\u00een primii no\u0219tri ani de via\u021b\u0103.<\/p>\n
\u00a0Cercet\u0103torii de la Yale\u00a0au negat acum aceast\u0103 variant\u0103 \u0219i spun c\u0103 bebelu\u0219ii \u00ee\u0219i formeaz\u0103 amintiri, dar nu le pot accesa c\u00e2nd devin adul\u021bi.\u00a0\u00a0<\/p>\n
Pentru studiul publicat \u00een revista\u00a0Science, cercet\u0103torii au ar\u0103tat la 26 de bebelu\u0219i o imagine a unei noi fe\u021be, un obiect sau scen\u0103, iar ulterior au testat dac\u0103 \u0219i-au amintit de ele ar\u0103t\u00e2ndu-le imaginea v\u0103zut\u0103 anterior al\u0103turi de una nou\u0103, relateaz\u0103\u00a0The Independent.<\/p>\n
\u201eC\u00e2nd bebelu\u0219ii au v\u0103zut ceva doar o singur\u0103 dat\u0103, ne a\u0219tept\u0103m s\u0103 se uite la el mai mult c\u00e2nd \u00eel vor vedea din nou\u201d, a spus profesorul Nick Turk-Browne, autorul principal al studiului.<\/p>\n
\u201eDac\u0103 un bebelu\u0219 se uit\u0103 la imaginea v\u0103zut\u0103 anterior mai mult dec\u00e2t la cea nou\u0103 de l\u00e2ng\u0103 ea, aceasta poate fi interpretat\u0103 de c\u0103tre copil ca fiind familiar\u0103\u201d, a ad\u0103ugat acesta.<\/p>\n
Cercet\u0103torii au efectuat scan\u0103ri ale creierului folosind imagistica prin rezonan\u021b\u0103 magnetic\u0103 func\u021bional\u0103 (fMRI) pentru a m\u0103sura activitatea din hipocampul sugarilor \u00een timp ce ace\u0219tia vizualizau imaginile.<\/p>\n
Cu c\u00e2t activitatea hipocampului este mai mare atunci c\u00e2nd un copil se uit\u0103 la o nou\u0103 imagine, cu at\u00e2t el se uit\u0103 mai mult la ea c\u00e2nd a reap\u0103rut mai t\u00e2rziu, au descoperit cercet\u0103torii.<\/p>\n
Cei mai mari de 12 luni au prezentat o activitate cerebral\u0103 mai puternic\u0103, suger\u00e2nd c\u0103 hipocampul se dezvolt\u0103 pentru a sprijini\u00a0\u00eenv\u0103\u021barea \u0219i memoria. Cercet\u0103rile anterioare ale echipei de la Yale au descoperit c\u0103\u00a0sugarii\u00a0de p\u00e2n\u0103 la trei luni prezint\u0103 un tip de memorie numit \u201e\u00eenv\u0103\u021bare statistic\u0103\u201d. \u00cen timp ce memoria episodic\u0103 se ocup\u0103 de evenimente specifice, \u201e\u00eenv\u0103\u021barea statistic\u0103\u201d se refer\u0103 la extragerea tiparelor \u00eentre evenimente, de exemplu, cum arat\u0103 un loc.<\/p>\n
