Tech Explorist’in haberine g\u00f6re, McGill \u00dcniversitesinde bilim insanlar\u0131, beyindeki “sinirsel pusula” ya da “i\u00e7 pusula” olarak bilinen ve y\u00f6n duygusunun temelini olu\u015fturan y\u00f6n merkezinin nas\u0131l \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131 anlamak i\u00e7in ara\u015ft\u0131rma yapt\u0131.<\/p>\n
Bilim insanlar\u0131, en son g\u00f6r\u00fcnt\u00fcleme teknikleriyle beyindeki sinirsel de\u011fi\u015fiklikleri izleyerek y\u00f6n merkeziyle ilgili yeni bilgiler elde etti.<\/p>\n

Sinirsel kay\u0131t teknolojisindeki son geli\u015fmeleri kullanan ekip, beynin i\u00e7 pusulas\u0131n\u0131n aktivitelerini benzeri g\u00f6r\u00fclmemi\u015f do\u011frulukla tespit etmeyi ba\u015fard\u0131.<\/p>\n

Harvard \u00dcniversitesinden ara\u015ft\u0131rmac\u0131 Zaki Ajabi, “Sanki kafa kar\u0131\u015ft\u0131r\u0131c\u0131 durumlarda beynin i\u00e7 pusulas\u0131n\u0131n h\u0131zl\u0131 bir \u015fekilde yeniden y\u00f6n\u00fcn\u00fc bulmas\u0131n\u0131 sa\u011flayan bir ‘s\u0131f\u0131rlama d\u00fc\u011fmesi’ varm\u0131\u015f gibiydi.” dedi.<\/p>\n
