Kala duwanaanshaha jinsiga ah ee jawaabaha dareenka iyo aragtida ayaa la soo gudbiyey daraasado cilmi-nafsiyeed oo hore iyo cilmi-nafsiyeed. Tusaale ahaan, dumarka ayaa lagu ogaadey in ay si xoogan uga jawaabaan dareenka diidmada ah, farqi jinsi ah oo lala xiriiriyay khatarta sii kordheysa ee niyad-jabka iyo xanuunka welwelka. Xaddiga sida farqiga jinsiga sida ka muuqata farqiga udhexeeya isdhexgalka gobolka maskaxeed ayaa weli ah arrin aan la xallilin, si kastaba ha ahaatee, qayb ahaan sababtoo ah daraasado yar oo yar yar ayaa ka hadlay arrintan. Halkan, adoo samaynay falanqayn qiimeyn ah oo ku saabsan baaritaannada neerogaraamka, waxaan awoodnay inaan si weyn u kordhino awoodda tirakoobka si loo ogaado kala duwanaanshaha jinsiga ee la xidhiidha daraasado hor leh, iyada oo la isku darsaday dareenka dareenka kaas oo si faahfaahsan u baaray kala duwanaanta jinsiga iyada oo tiro badan oo daraasado ah oo baaray haweenka oo keliya ama ragga. Waxaan adeegsanay habka ku-meel-gaadhka ah ee ku-meel-gaadhka ah ee loogu talagalay in lagu garto khilaafaadka galmada ee suurtogalka ah ee hawlaha maskaxeed ee gobolka oo ay ka heleen dareenka dareenka ee ku saabsan dareenka aan dareenka lahayn. Waxaanu si gaar ah u eegnay kala duwanaanshaha galmada si aan fiicnayn iyo kalsooni wanaagsan, marka lagu daro baaritaanka dhammaan dareenada oo dhan. Farogelinta jinsiga ayaa si kala duwan u kala duwanaa dareenka dareenka iyo dareenka wanaagsan. Inta badan farqiga kala duwanaanshaha galmada ee dumarka ayaa loo arkay dareen aan fiicneyn, halka inta badan farqiga kala duwanaanta jinsiga ee ragga ay u arkaan dareen wanaagsan. Muhiimaddan qiimaha leh wuxuu si gaar ah uga muuqday amygdala. Dareenka xun, haweenku waxay soo bandhigeen firfircooni ka badan ragga amygdala bidix, iyo sidoo kale gobollada kale oo ay ka mid yihiin hindhisyada bidix, hypothalamus, mammillary, coodad ka baxsan, iyo kortex hore. Taa bedelkeeda, dareenka wanaagsan, ragga ayaa soo bandhigay dhaqdhaqaaq ka badan haweenka ku jira amygdala bidix, iyo sidoo kale hawlgal ballaaran oo gobollada kale ah oo ay ka mid yihiin gyrus horjeeda hoose iyo gurraska fusiform. Natiijooyinkan falanqaynta maadada ayaa muujinaya in amygdala, gobolka muhiimka ah ee habka dareenka, ay muujiso kala duwanaansho galmoodka qiimaha leh ee lagu dhiirigeliyo dareenka dareenka. Jawaabta ugu weyn ee bidix ee amygdala ee dareenka xun ee haweenka u dhiganta warbixinno hore oo ay haweenku si aad ah uga jawaabaan kicinta dareenka xun, iyo sidoo kale xiriiro la isku halleyn karo oo dhexmara fal-celinta nuuriyoolojiga ilaa dareen xun iyo korodhka baahsanaanta niyadjabka iyo xanuunka walaaca ee haweenka. Natiijada helitaanka firfircoonida bidix ee amygdala ee loogu talagalay dareenka maskaxeed ee ragga ahi waxay muujinayaan in jawaabaha amygdala ee hore loo soo sheegey ragga loogu talagalay noocyada gaarka ah ee xiisaha wanaagsan ay sidoo kale u gudbin karaan xeeldheer guud ahaan guud ahaan. Dulucda, daraasaddaani waxay sii ballaarineysaa dadaallada lagu garto kala duwanaanshaha isutagga maskaxda ee hawlgalka maskaxda inta lagu jiro farsamaynta dareenka iyadoo la bixinayo falanqaynta miisaaniyada ee ugu weyn iyo tan ugu ballaaran ilaa taariikhda, iyo marka ugu horreysa ee lagu baaro kala duwanaanta jinsiga sida shaqeyn wanaagsan oo la mid ah. Muujinta dareenka xun.
