Os resultados foram publicados na revista cient\u00edfica PNAS (Proceedings of the National Academy of Sciences), uma das mais respeitadas na \u00e1rea acad\u00eamica.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Segundo os cientistas, ao aplicar est\u00edmulos leves em regi\u00f5es espec\u00edficas do c\u00e9rebro ligadas \u00e0 empatia e \u00e0 tomada de decis\u00e3o moral, os participantes passaram a demonstrar maior disposi\u00e7\u00e3o para dividir recursos com outras pessoas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Como os pesquisadores realizaram o experimento<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A equipe utilizou uma t\u00e9cnica chamada estimula\u00e7\u00e3o transcraniana por corrente cont\u00ednua (tDCS), considerada n\u00e3o invasiva. Durante o experimento, volunt\u00e1rios participaram de jogos econ\u00f4micos nos quais precisavam decidir quanto dinheiro compartilhar com desconhecidos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Parte do grupo recebeu estimula\u00e7\u00e3o direcionada ao c\u00f3rtex pr\u00e9-frontal dorsolateral, regi\u00e3o associada ao controle emocional e decis\u00f5es sociais. Enquanto isso, outro grupo passou por um procedimento simulado, sem est\u00edmulo real, para servir de compara\u00e7\u00e3o.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">O que os resultados mostraram<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Os pesquisadores observaram que os participantes que receberam estimula\u00e7\u00e3o real apresentaram maior tend\u00eancia a dividir os valores de forma mais equilibrada. Ou seja, demonstraram comportamentos mais altru\u00edstas em compara\u00e7\u00e3o ao grupo controle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De acordo com os autores do estudo, isso sugere que determinadas \u00e1reas do c\u00e9rebro desempenham papel direto na forma como avaliamos justi\u00e7a, coopera\u00e7\u00e3o e generosidade.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">O que isso significa?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Apesar dos resultados promissores, os cientistas ressaltam que a t\u00e9cnica ainda est\u00e1 em fase experimental dentro da\u00a0ci\u00eancia. Portanto, n\u00e3o se trata de uma ferramenta pronta para aplica\u00e7\u00e3o cl\u00ednica ou social.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ainda assim, a pesquisa da Universidade de Zurique amplia o entendimento sobre como os circuitos neurais influenciam decis\u00f5es morais e comportamentos pr\u00f3-sociais. Al\u00e9m disso, abre caminho para investiga\u00e7\u00f5es futuras sobre empatia, coopera\u00e7\u00e3o e funcionamento do c\u00e9rebro humano.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Foto: Shutterstock <strong>\/ <\/strong>Fonte: Fatos Desconhecidos <\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tempo de leitura: 2 minutos Um estudo que surpreende Um estudo conduzido por pesquisadores da<\/p>\n","protected":false},"author":3,"featured_media":4578,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-4577","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-curiosidades-2"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
