Chitsanzo chatsopano cha nyama chingathandize asayansi kupeza momwe ubongo wazimayi umachitira ndi chiwawa.
Asayansi a Rutgers atengapo mbali kuti amvetse momwe chiwawa cha kugonana chimasinthira ubongo wazimayi.
Mu kufufuza kwaposachedwapa Scientific Reports, wolemba mabuku wotchedwa Tracey Shors, pulofesa mu Dipatimenti ya Psychology ndi Center for Collaborative Neuroscience ku Sukulu ya Zojambula ndi Sayansi, adapeza kuti makoswe achikazi omwe analipo kale omwe anali ndi zibwenzi zogonana anali ndi mahomoni opsinjika, omwe sankakhoza kuphunzira, zochepetsera zoyenera zochepetsera amayi kuti zisamalire ana.
"Phunziroli ndi lofunika chifukwa tiyenera kumvetsetsa momwe zachiwerewere zimakhudzira mitundu yonse," adatero Shors. "Tiyeneranso kudziwa zotsatira za khalidweli kuti tidziwe zomwe tingachite kuti tithandizire amayi kuti apezenso zachiwawa komanso zachiwawa."
Azimayi makumi atatu pa 100 alionse padziko lonse amakumana ndi ziwawa zina zapakati pa moyo wawo komanso atsikana omwe ali ndi zaka zambiri kuposa anthu onse omwe amazunzidwa, amayesa kugwiriridwa kapena kuzunzidwa, malinga ndi World Health Organization. Kafukufuku waposachedwapa amasonyeza kuti ambiri mwa ophunzira asanu alionse a ku koleji amakumanapo chiwawa chogonana pa zaka zapunivesite.
Azimayi amene amachitira nkhanza za kugonana amakhala ovutika maganizo, PTSD ndi zina mavuto a maganizo. Komabe, ngakhale kugwirizana kosavomerezeka pakati chiwerewere ndi thanzi lamaganizidwe, ndizochepa zomwe zimadziwika momwe nkhanza zimakhudzira ubongo wachikazi. Mwa zina, ndichifukwa sipanakhale mtundu wovomerezeka wa labotale wowerengera zomwe zimachitika chifukwa cha nkhanza zogonana komanso machitidwe ogwirira ntchito mu akazi, a Shors adatero.
"Zoyeserera zasayansi zomwe zimagwiritsidwa ntchito poyesa kupsinjika kwa nyama kale zimayang'ana momwe kupsinjika kumakhudzira amuna ndipo sizikuwonetsa kupsinjika komwe atsikana amakumana nako," adatero.
Shors anati, "Chifukwa chake National Institutes of Health tsopano ikufuna kuti nyama ndi abambo aziphatikizidwa mu kafukufuku kuti apeze ndalama zothandizira boma.
Mu phunziro latsopano la Rutgers, Shors ndi anzake amagwiritsa ntchito chitsanzo cha Sexual Conspecific Aggressive Response (SCAR) kuti adziwe momwe kupsinjika kokhudza kugonana kunakhudza makoswe aakazi.
Ngakhale sizachilendo kuti makoswe achikazi azisamalira ana awo, komanso ana a makoswe ena, a Shors ati azimayi omwe adachita nawo kafukufukuyu omwe amawonetsedwa kwa amuna akulu nthawi yonse yakutha msinkhu sanawonetse machitidwe azimayi monga akazi omwe adachita osakhala ndi machitidwe achiwawawa. Ngakhale panalibe kuchepa kwa neurogenesis (kapangidwe ka ma cell aubongo), ma cell am'magazi omwe adangopangidwa kumene amakhalabe mwa akazi omwe samafotokoza momwe amayi amakhalira poyerekeza ndi akazi omwe adaphunzira kusamalira ana.
Ngakhale asayansi sakudziwa ngati nkhanza zamtunduwu zitha kukhala ndi zomwezo mwa anthu, kafukufuku wasonyeza kuti chiwerewere ndipo chiwawa ndi chimodzi mwa zifukwa zomwe zimachititsa kuti PTSD ikhale yazimayi, chikhalidwe chomwe chimakhudzana ndi kuchepa kwa ubongo zomwe zikugwirizana ndi kuphunzira ndi kukumbukira. Ana azimayi amene amachitirana nkhanza za kugonana ali pachiopsezo chachikulu chokumana ndi zowawa zomwe akukumana nazo pamene akukula.
"Tikudziwa zochepa kwambiri za njira zamaubongo zomwe zimawonjezera kukhumudwa komanso kusokonezeka kwa malingaliro pakati pa azimayi omwe ali ndi vuto lachiwerewere komanso nkhanza," adatero Shors. "Koma ndi njira zatsopano ndikuwunika nkhaniyi, titha kudziwa momwe mkaziyo ubongo Amayankha zachiwawa komanso momwe angathandizire azimayi kuti aphunzire zachiwerewere. ”
Fufuzani zina: Mavuto okhudzana ndi kugonana amasiyana ndi abambo, abambo
