Un nou studiu publicat \u00een Neurobiology of Sleep and Circadian Rhythms arat\u0103 c\u0103 lumina albastr\u0103 poate influen\u021ba direct reactivitatea de baz\u0103 a creierului, amplific\u00e2nd excitabilitatea cortical\u0103 la adul\u021bii tineri, \u00een timp ce la adolescen\u021bi acest efect este practic absent, conform PsyPost<\/a><\/span>.<\/p>\n

Constat\u0103rile eviden\u021biaz\u0103 o rela\u021bie complex\u0103 \u0219i neliniar\u0103 \u00eentre expunerea la lumin\u0103 \u0219i func\u021bia neural\u0103, suger\u00e2nd c\u0103 v\u00e2rsta joac\u0103 un rol esen\u021bial \u00een modul \u00een care creierul reac\u021bioneaz\u0103 la lumina din mediu.<\/p>\n

Lumina albastr\u0103 cre\u0219te excitabilitatea cortical\u0103 doar la niveluri moderate<\/h2>\n

Cercet\u0103torii au descoperit c\u0103 expunerea adul\u021bilor tineri la lumin\u0103 albastr\u0103 de intensitate moderat\u0103 a produs o cre\u0219tere semnificativ\u0103 a excitabilit\u0103\u021bii corticale comparativ cu lumina portocalie, chiar dac\u0103 cele dou\u0103 p\u0103reau la fel de luminoase.<\/p>\n

Totu\u0219i, lumina albastr\u0103 de intensitate mai mare nu a amplificat acest efect \u0219i a indicat, dimpotriv\u0103, o tendin\u021b\u0103 de reducere a excitabilit\u0103\u021bii, suger\u00e2nd un model \u00een form\u0103 de U inversat, asociat performan\u021bei cognitive optime.<\/p>\n

Adolescen\u021bii nu prezint\u0103 modific\u0103ri detectabile \u00eentre condi\u021biile de lumin\u0103<\/h2>\n

\u00cen contrast, adolescen\u021bii nu au prezentat modific\u0103ri semnificative ale excitabilit\u0103\u021bii corticale \u00een niciuna dintre cele trei condi\u021bii de lumin\u0103 testate.<\/p>\n

Cercet\u0103torii sus\u021bin c\u0103 factori precum lentilele mai clare, pupilele mai mari \u0219i ritmurile circadiene aflate \u00een schimbare pot influen\u021ba sensibilitatea lor la lumin\u0103, subliniind necesitatea unor recomand\u0103ri adaptate v\u00e2rstei.<\/p>\n

Reactivitatea neural\u0103 prezice performan\u021ba comportamental\u0103<\/h2>\n

\u00cen ciuda diferen\u021belor fiziologice, at\u00e2t adul\u021bii tineri, c\u00e2t \u0219i adolescen\u021bii au prezentat o corela\u021bie puternic\u0103 \u00eentre excitabilitatea cortical\u0103 \u0219i performan\u021ba \u00eentr-o sarcin\u0103 de vigilen\u021b\u0103 ce necesita aten\u021bie sus\u021binut\u0103.<\/p>\n

Nivelurile mai ridicate de excitabilitate au prezis constant o performan\u021b\u0103 mai bun\u0103, indiferent de tipul de lumin\u0103.<\/p>\n

Implica\u021bii \u0219i direc\u021bii viitoare de cercetare<\/h2>\n

Studiul sugereaz\u0103 c\u0103 lumina albastr\u0103 poate influen\u021ba direct reactivitatea neural\u0103 \u00een timpul zilei, \u00eens\u0103 beneficiile depind de intensitate, iar expunerea excesiv\u0103 ar putea reduce excitabilitatea.<\/p>\n

Autorii subliniaz\u0103 necesitatea unor cercet\u0103ri suplimentare privind influen\u021ba momentului din zi, a unor game mai largi de intensit\u0103\u021bi \u0219i a diferen\u021belor de sensibilitate \u00eentre etapele de dezvoltare.<\/p>\n","protected":false},"excerpt":{"rendered":"
