Uropi hune nzvimbo dzakasiyana dzine mabasa akasiyana. Idiki uye ine simba kwazvo, asi nekufamba kwemakore isu tinorasikirwa nesimba uye "simba rekudyara" rinowanzo kuderera mukuita. Iyo hippocampus inzvimbo ine mabasa ane chekuita nekudzora manzwiro uye ndangariro, uye ongororo ichangobva kuitika inovimbisa kuti kurovedza muviri kunogona kubatsira kuchengetedza kushanda kwakanaka.
Ndeapi maekisesaizi emuviri atinoda kuti hippocampus ishande sezvainofanira kuita?
Kumwe kuongorora Zvidzidzo zvakapfuura zvakawana kuti mamwe maitiro emararamiro anogona kuita mutsauko, kunyanya kudzorwa necalorie uye kurovedza muviri. Muchidzidzo chataurwa pamusoro apa, vatsvakurudzi vanoratidza kuti hazvisi zvakawanda sezvaungafunga. Muchokwadi, muchikamu chimwe chete chekurovedza muviri unogona kutaura mutsauko.
Chidzidzo ichi, chakabudiswa mu Journal of the International Neuropsychological Society, chakanangana ne semantic memory, ndiko kugona kwatinofanira kurangarira mazwi, pfungwa uye nhamba, uye mhedzisiro yekurovedza muviri pa hippocampal activation.
Nezveizvi, vaive nevatori vechikamu makumi maviri nevatanhatu, vari pakati pemakore makumi mashanu nemashanu nemakumi masere nemashanu, uye vakavaisa pakuzorora kana maminetsi makumi matatu ekurovedza muviri kwemazuva maviri akasiyana. Pakarepo, vakapiwa MRI uye vakakumbirwa kuti vayeuke mazita evanhu vane mukurumbira nevasina mukurumbira.
Muyedzo yekumashure-yekurovedza muviri, vakawana mubhadharo yakakwirira zvikuru maererano memory, zvichienzaniswa neapo vazvipiri vakangozvitsaurira kuti vazorore kwehafu yeawa. Vakanga vasina imwe chete yakawedzera activation muhippocampus, asi mamwe mativi europi akaitwawo kushanda.
«Kubva pane zvidzidzo zvakapfuura, tinoziva kuti kurovedza muviri nguva dzose kunogona kuwedzera huwandu hwese hwehippocampus, uye kudzidza kwedu kunoratidza kuti kunyange muchikamu chimwe chete chekurovedza muviri tinogona kuita zvakakosha.akadaro munyori anotungamirira J. Carson Smith.
Sei maekisesaizi achiunza izvi zvinobatsira?
Zvakaoma kuziva mashandiro europi. Pane huwandu hwemikana yekuti sei kurovedza muviri kunoita kuti uropi hushande zvirinani. Munyori wechidzidzo ichi anoti zvinogona kunge zvine chekuita nea kuwedzera mune neurotransmitters, zvakadai se norepinephrine uye dopamine, iyo inowedzera "chiratidzo kune ruzha." Izvi zvinoreva kuti neural network inogona kushandiswa zvakanyanya.
Iyo yekurangarira-inosimudzira mhedzisiro kune vatori vechikamu chidzidzo yakagara kweinenge awa imwe chete mushure mechikamu chega chega chekurovedza muviri. Asi kunyangwe mhedzisiro yacho ichizopera zvishoma mushure menguva iyoyo, kudzidziswa nguva dzose kunogona kubatsira neural network uye hippocampus. Ngatitii zvakafanana ne "kudzidzisa" uropi, sezvatinodzidzisa tsandanyama.
«Hatina nguva yakareba yekutevera kuti tisimbise izvozvo, asi zvichibva pachidzidzo ichi uye kumwe kutsvagurudza, zvinogoneka kuti nekufamba kwenguva, uropi hunoenderana nekuita maekisesaizi nenzira yakafanana nemuviri.. Uropi hunowedzera kusimba«. Nemhedziso iyi, anoisa kupedzisa kune nhema dzenhema dzekuti vanhu vanoenda kumitambo yekurovedza muviri havana akawanda neuroni (kunyangwe isu taitoziva izvozvo).
