Iinyembezi zabasetyhini ziqulethe iikhemikhali ezithintela ukuxhatshazwa kwamadoda, uphando olwenziwa ngoososayensi base-Israel, olukhankanywe yi-electronic edition "Euricalert".
Iingcali ezivela kwi-Weizmann Institute of Science zifumene ukuba iinyembezi zikhokelela ekunciphiseni umsebenzi wobuchopho ohambelana nobudlova, nto leyo inciphisa ukuziphatha okunjalo kubameli bezesondo ezinamandla. Umphumo uvela emva kokuba amadoda "evumba" iinyembezi.
Ubundlongondlongo bamadoda kwiimpuku kwaziwa ngokuba buthintelekile xa benuka iinyembezi zemizekelo yabasetyhini. Lo ngumzekelo we-social chemosignaling, inkqubo eqhelekileyo kwizilwanyana kodwa ixhaphake kakhulu-okanye ingaqondwa kakuhle-kubantu. Ukubona ukuba banempembelelo efanayo ebantwini, abaphandi baqaphela impembelelo yeenyembezi zengqondo yabasetyhini kwiqela lamadoda athathe inxaxheba kumdlalo okhethekileyo wababini. Ngenjongo yolu hlolisiso, amanye amatsha-ntliziyo anikwa ityuwa endaweni yokulila.
Umdlalo ulungiselelwe ukuxhokonxa impatho erhabaxa ngakumchasi obonwa njengomntu oqhathayo. Xa enikwa ithuba, amadoda anokuziphindezela kumntu okhuphisana naye ngokumenza alahlekelwe yimali. Abameli besini esinamandla abazi ukuba bavumba kwaye abanako ukwahlula phakathi kweenyembezi kunye ne-saline, ezingenavumba.
Ukuziphatha okukhohlakeleyo okujolise ekubuyiseleni ngexesha lomdlalo kwehle ngaphezu kwe-40% emva kokuba amadoda afikelele kwiinyembezi zeemvakalelo zabasetyhini, ngokwedatha yakwa-Israel.
Ekuhlolweni kwakhona nge-imaging resonance magnetic, imaging esebenzayo ibonise imimandla emibini yobuchopho ehambelana nobudlova - i-cortex yangaphambili kunye ne-insula yangaphambili. Ziye zisebenze xa amadoda ecatshukiswa ngexesha lomdlalo, kodwa ayenziwanga kakhulu kwiimeko ezifanayo xa abameli besini esinamandla bephantsi kweempembelelo zeenyembezi. Ngaphezu koko, kuyacaca ukuba okukhona umahluko omkhulu kulo msebenzi wengqondo, kokukhona umchasi engaziphindezeli ngexesha lomdlalo.
Ukufunyaniswa kolu nxibelelwano phakathi kweenyembezi, umsebenzi wobuchopho kunye nokuziphatha okukhohlakeleyo kubonisa ukuba i-chemosignaling yentlalo yinto ebangela ubundlobongela bomntu kunokuba nje isilwanyana sifune ukwazi.
“Sifumanise ukuba, njengeempuku, iinyembezi zomntu zikhupha umqondiso wemichiza othintela ugonyamelo lwamadoda. Oku kuyangqubana nembono yokuba iinyembezi zeemvakalelo zingumntu okhethekileyo,” zaphawula izazinzulu zakwaSirayeli, ezikhokelwa nguShani Agron.
