Po tej &#8220;vozni\u0161ki kabini&#8221; so speljali bakreno \u017eico, in to tako, da je tvorila tri palice &#8211; levo, sredinsko in desno.<\/p>\n<p>Ko se je ena izmed 17 v \u0161tudiji sodelujo\u010dih podgan usedla v kabino oz. na aluminijasto dno in se dotaknila \u017eic, je sklenila omre\u017eje in avto se je lahko premikal v smer, ki ga je izbrala. Sedemnajsterico glodavcev so ve\u010d mesecev urili za vo\u017enjo po prostoru iz pleksi stekla v velikosti 150 krat 60 centimetrov.<\/p>\n<p>Znanstveniki so v prispevku za publikacijo Behavioural Brain Research zapisali, da so podgane lahko nau\u010dili vo\u017enje naprej, pa tudi obra\u010danja in nekaterih drugih kompleksnih navigacijskih operacij.<\/p>\n<p>Ugotovili so, da so se podgane v stimulacijsko bogatem okolju odrezale veliko bolje od svojih laboratorijskih kolegic. To je Lambertova \u017ee vnaprej domnevala, a velik dose\u017eek \u017eivali jo je vseeno presenetil.<\/p>\n<p>Po vo\u017enji so raziskovalci pobrali vzorce blata podgan in v njih preu\u010dili ravni stresnega hormona kortikosterona, pa tudi hormona dehidroepiandrosterona, ki je tisti, ki se stresu zoperstavi. Pri vseh podganah, ki so jih u\u010dili voziti, so odkrili vi\u0161je ravni dehidroepiandrosterona, kar ka\u017ee, da so bile bolj spro\u0161\u010dene. To pa bi bilo lahko povezano z u\u017eitkom ob tem, da so se nau\u010dile nove ve\u0161\u010dine.<\/p>\n<p>Pokazalo se je tudi, da so imele tiste podgane, ki so vozile same, vi\u0161je ravni dehidroepiandrosterona od tistih, ki so bile le &#8220;potnice&#8221; v avtomobil\u010dku, ko so tega upravljali od zunanj. To pomeni, da so bile kot voznice v manj\u0161em stresu &#8211; tako je pogosto tudi pri ljudeh, ko so bolj od voznika \u017eiv\u010dni sopotniki, predvsem tisti na zadnjih sede\u017eih.<\/p>\n<p>Lambertovo je pri raziskavi najbolj navdu\u0161il njen potencial za odkrivanje novih na\u010dinov zdravljenja ljudi, ki trpijo za du\u0161evnimi boleznimi. &#8220;Za shizofrenijo ali depresijo ni zdravila,&#8221; je opozorila. &#8220;Mislim, da moramo to nadoknaditi in preu\u010diti razli\u010dne \u017eivalske modele, razli\u010dne naloge ter resni\u010dno prepoznati, da lahko obna\u0161anje spremeni na\u0161o nevrokemijo,&#8221; je poudarila.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ameri\u0161ki znanstveniki zatrjujejo, da so s sladkimi \u017eitaricami podgane uspe\u0161no nau\u010dili voziti avtomobil\u010dke.
