Hippocampus waa maskaxda maskaxda kaliya ee ku jirta xarumaha dhexdhexaadka ah. Waxay u dhigantaa qaabka loo yaqaan "seahorse", waxaana jira hal dhinac dhinac kasta oo maskaxda ka sarreeya dhegaha.
Maxay Tahay
Hippocampus wuxuu naga caawinayaa inaan horumarinno xasuusno cusub. Mararka qaarkood waxaa loo arkaa in albaabku uu xasuusiyo sida xasuusta ay u baahantahay in loo maro hippocampus si ay ugu kaydiso bangiga xasuusta mudada dheer .
Cilmi-baarisyada qaar ayaa sidoo kale muujiyay in hippocampus ay muhiim u tahay uunan abuurin xusuus cusub, lakiin sidoo kale dib u soo xasuusashada xusuusta hore.
Arrinta xiisaha badan, hippocampus dhinaca bidixda badanaa wuxuu leeyahay shaqeyn weyn oo xasuusta iyo luqadda ah mid ka mid ah dhinaca dhinaca midig.
Sida Cudurka Alzheimer u saameeyo Hippocampus
Cilmi baaris ayaa lagu ogaaday in mid ka mid ah meelaha ugu horreeya ee maskaxda ee uu saameeyo cudurka Alzheimers uu yahay hippocampus. Cilmi-baadhayaashu waxay isku-xidhxidhaan atrophy (yareyn) ee meelaha hippocampal iyadoo joogitaanka cudurka Alzheimers. Atrophy-ka qeybtan ee maskaxda ayaa ka caawiya sharaxaadda sababta mid ka mid ah calaamadaha ugu horeeya ee cudurka Alzheimers uu badanaaba niyadjab ku yahay, gaar ahaan sameynta xusuusta cusub.
Hippocampus atrophy ayaa sidoo kale la xiriirta joogitaanka borotiinka la yiraahdo taasoo ka dhiganaysa jiritaanka cudurka Alzheimers.
Dhibaatada Fahamka Khafiifka ah
Sidaa awgeed, xajmiga iyo mugga hippocampus ayaa si cad u saameeya cudurka Alzheimers.
Laakiin waxa ku saabsan dhibaatooyinka khafiifka ah ee khafiifka ah, xaalad mararka qaarkood, laakiin had iyo goorba, ma sii socdo cudurka Alzheimers?
Cilmi-baaristu waxay muujisay in xitaa hippocampus ay sidoo kale ku xiran tahay cilladda khafiifka khafiifka ah . Xaqiiqdii, xajmiga hippocampus iyo xaddiga qallajinta ayaa loo soo bandhigay si loo saadaaliyo in MCI uu u socdo cudurka Alzheimer ama haddii kale.
Mugga yar ee hippocampal iyo sicirka degdegga ah ama hoos udhaca ayaa isku xira horumarka waallida.
Miyuu Hippocampal Volume Iskudhin Karaa Noocyada kala duwan ee Asaasaqa?
Daraasado cilmi baaris oo dhowr ah ayaa qiyaasay mugga hippocampal waxayna eegeen sida ay ula xiriirto noocyada kale ee waallida. Hal suurtagal ayaa ah in dhakhtarradu ay isticmaali karaan xajmiga xanuunka hippocampal si ay u caddeeyaan nooca asaasaqidda.
Tusaale ahaan, haddii cudurka Alzheimers uu yahay nooca kaliya ee waallida oo si weyn u saameeya xajmiga hippocampus, tan waxaa loo isticmaali karaa si cilad ah loogu ogaado Alzheimers. Hase yeeshee, daraasado badan ayaa muujiyay in qiyaastaas aan badanaa aysan waxtar u lahayn kala duwanaanshaha noocyada kala duwan ee waallida.
Hal baadhis oo lagu daabacay wargeyska ' Neurodegenerative Diseases' ayaa qeexay in tirada yar ee hippocampus ay ka dhaceen waallida 'dementia' .
Daraasad labaad ayaa lagu ogaaday in xaddiga hippocampal hoos u dhacay ay sidoo kale xidhiidh la leedahay jahawareerka hore ee waallida .
Cilmi-baadhayaashu waxay ogaadeen isbadal muuqda, si kastaba ha ahaatee, marka la barbardhigo Lewy waallida wadnaha ee cudurka Alzheimers. Dhiigga Lewy ee jidhka ayaa muujinaya in farqi yar oo ka mid ah meeraha hippocampal ee maskaxda, taas oo sidoo kale ku dhacda saameyn yar oo muhiim ah oo xasuusta ah, gaar ahaan marxaladaha hore ee waallida waallida .
Miyaad Ka Hortagi kartaa Hippocampus-kaaga Dab-demiska?
Baaxadda (ereyga awoodda maskaxda ee koritaanka iyo isbedelka waqtiga) ee hippocampus ayaa lagu soo bandhigay marar badan cilmi baaris. Cilmi-baaris ayaa la ogaaday in, in kasta oo hippocampus uu ku dhaco qallal-celin marka loo eego da'da, jimicsiga jireed iyo kicinta garashada (maskaxeed maskaxeed) waxay yareeyn kartaa qashinkaas, mararka qaarkoodna xitaa dib u noqota.
