DULSHADA:
Khamaarista ayaa ku boorrisay khamaarka noolaha (PG) inta badan isla markiiba kahortaga kaqeybgalka dabeecadda khamaarka is-halaagga ah. Fahamka la hagaajiyay ee isku xidhka neerfaha ee khamaarista ku dhiirrigelinta PG wuxuu horumarin doonaa fahamkeenna ku saabsan farsamooyinka maskaxda ee salka ku haya PG waxayna gacan ka geysan doontaa in si toos ah loo baaro daaweynta wax ku oolka ah
XISBIGA:
Sawirka Echoplanar ee magnetic resonance imaging ayaa loo isticmaalay in lagu qiimeeyo shaqada maskaxda inta lagu gudajiro daawashada xaaladaha muuqaalka ah ee khamaarka, farxadda, ama waxyaabaha murugada leh. Kaqeybgalayaashu waxay qiimeeyeen tayada iyo baaxada jawaabahooda shucuur iyo dhiirigalin.
Natiijooyinka:
Ragga qaba PG (n = 10) waxay soo sheegeen celcelis +/- SD khamaaris badan oo kufsi leh ka dib markaad daawato xaaladaha khamaarka iyo maadooyinka xakamaynta (n = 11) (5.20 +/- 3.43 vs 0.32 +/- 0.60; chi21,19 = 21.71; P < ) .001) Kooxuhu si weyn ugama duwaneyn jawaabahooda shakhsiga ah ee farxadda leh (P = .56) ama murugo (P = .81) cajaladaha fiidiyowga. Kala duwanaanshaha udhaxeeya ee udhaxeeya kooxaha neerfaha ayaa la arkay inta lagu gudajiray mudadii bilowga ee daawashada xaaladaha khamaarka: Mawduucyada 'PG' waxay soo bandhigeen waxqabad yaraaday xagga hore iyo kortex orbitofrontal, caudate / basal ganglia, iyo thalamus marka lala barbardhigo kantaroolka. Qaababka kaladuwan ee dhaqdhaqaaqa maskaxda gobolka ayaa lagu arkay xilliyadii gaarka ahaa ee fiidiyowga la daawanayay. Tusaale ahaan, kala duwanaanshaha ku-xirnaanshaha marinka marinka hore ee marinka jirka inta lagu jiro muddada ugu dambeysa ee daawashada cajaladda fiidiyowga ee khamaarka, oo u dhiganta soo bandhigidda dhiirrigelinta khamaarka ugu kicin badan. In kasta oo kala duwanaanshaha kooxeed ee dhaqdhaqaaqa maskaxda la arkay intii lagu jiray daawashada xaaladaha murugada iyo farxadda leh, waxay ka duwanaayeen kuwa u dhigma dhacdooyinka khamaarka.
XUSUUS:
Ragga qaba PG, soo bandhigida tilmaamidda khamaarka waxay keeneysaa dhiirrigelinta khamaarka waxayna u horseeddaa qaab firfircoon oo firfircoon oo dhaqdhaqaaqa maskaxda isbeddel ku yimaada qaab dhismeedka maskaxda, paralimbic, iyo limbic limbic. Markaad daawaneysid tilmaamaha khamaarka, maadooyinka PG waxay muujinayaan waxqabadka yaraaday ee gobollada maskaxda ee ku lug leh qawaaniinta kicinta marka la barbar dhigo kontaroolada.
