Yankho la funso, kodi nsomba zimakumbukira zotani, zimaperekedwa ndi kafukufuku wa akatswiri a zamoyo. Amati nzika zawo (zaulere ndi zam'madzi) zimawonetsa kukumbukira kwakanthawi kwakanthawi komanso kwakanthawi.
Japan ndi zebrafish
Pofuna kumvetsetsa momwe kukumbukira kwa nsomba kumapangidwira kwa nthawi yayitali, asayansi a sayansi ya mitsempha awona zebrafish: ubongo wake wowonekera wowoneka bwino ndikosavuta kuyesera.
Ntchito zamagetsi zamaubongo zidalembedwa pogwiritsa ntchito mapuloteni amtundu wa fluorescent, majini omwe adalowetsedwa mu DNA ya nsombayo pasadakhale. Pogwiritsa ntchito kutulutsa kwamagetsi pang'ono, adaphunzitsidwa kuti achoke pagawo la aquarium pomwe diode yamtambo idayatsidwa.
Kumayambiriro koyesera, ma neuron owoneka bwino aubongo anali osangalala patadutsa theka la ola, ndipo patangopita tsiku limodzi ma forebrain neurons (ofanana ndi ma hemispheres am'magazi mwa anthu) adatenga ndodoyo.
Chingwe ichi chikangoyamba kugwira ntchito, momwe nsomba inayankhira inathamanga: mphepo yamtundu wabuluu idayambitsa zochitika zaminyewa zomwe zimawonedwa, zomwe zimayatsa ma neuron a forebrain mu theka lachiwiri.
Ngati asayansi atachotsa malowa ndi ma neuron okumbukira, nsombazo sizinathe kuloweza. Iwo anali ndi mantha ndi diode yabuluu atangotengeka ndi magetsi, koma sanachitepo kanthu pambuyo pa maola 24.
Komanso, akatswiri a sayansi ya zamoyo ku Japan apeza kuti ngati nsomba ibwezeretsedwa, kukumbukira kwake kwanthawi yayitali kumasinthidwa, osapangidwanso.
Kukumbukira nsomba monga chida chopulumukira
Ndimakumbukiro omwe amalola nsomba (makamaka omwe amakhala m'malo osungira zachilengedwe) kuti azolowere dziko lowazungulira ndikupitiliza mpikisano wawo.
Zambiri zomwe nsomba zimakumbukira:
- Madera okhala ndi zakudya zabwino.
- Zingwe ndi nyambo.
- Kuwongolera kwa mafunde ndi kutentha kwamadzi.
- Malo omwe angakhale oopsa.
- Adani achilengedwe ndi abwenzi.
- Malo ogona usiku wonse.
- Nyengo.
Kukumbukira nsomba 3 masekondi kapena kuchuluka kwa kukumbukira nsomba
Simudzamvanso chiphunzitso chabodza ichi kuchokera kwa katswiri wazachthyologist kapena msodzi, yemwe nthawi zambiri amapeza "centenarians" am'nyanja ndi amtsinje, omwe amakhala ndi moyo nthawi yayitali chifukwa chokumbukira nthawi yayitali.
Nsombazi zimakumbukira pokumana ndi kutentha. Chifukwa chake, carp imasankha nyengo yozizira malo omwewo, omwe amapezeka kale.
Bream yomwe yagwidwa, ngati itayikidwa chizindikiro ndikutulutsa pang'ono kumtunda kapena kutsika, imabwereradi kumalo okopekerako.
Khola lomwe limakhala pagulu limakumbukira anzawo. Carps amawonetsanso zofananira, akusochera kumayandikira (kuyambira anthu awiri mpaka makumi makumi). Gulu lotereli lakhala likutsogolera moyo womwewo kwazaka zambiri: limodzi amapeza chakudya, amasambira mbali imodzi, amagona.
Asp nthawi zonse amayenda mumsewu umodzi ndikudya "zake", kamodzi komwe amasankhidwa ndi iye.
Zoyesera m'malo osiyanasiyana padziko lapansi
Pozindikira ngati nsomba zikukumbukira, akatswiri azamoyo adazindikira kuti nzika zam'madzi zimatha kupanga zithunzi zofananira. Izi zikutanthauza kuti nsomba zimapatsidwa kukumbukira kwakanthawi kochepa (chizolowezi) komanso kukumbukira kwakanthawi (kuphatikizapo kukumbukira).
Yunivesite ya Charles Sturt (Australia)
Ochita kafukufuku anali kufunafuna umboni wosonyeza kuti nsomba zimatha kukumbukira bwino kuposa momwe zimaganiziridwira. Ntchito yoyeserera idasewera ndi mchenga wamchenga wokhala m'madzi oyera. Zidachitika kuti nsombayo idakumbukira ndikugwiritsa ntchito njira zosiyanasiyana, kusaka mitundu iwiri ya nyama zake, komanso kukumbukira miyezi momwe idakumana ndi chilombo.
Kukumbukira kwakanthawi kansomba (kosapitilira masekondi ochepa) kunatsimikizidwanso kuyesedwa. Olembawo adaganiza kuti ubongo wa nsomba umasunga zidziwitso kwa zaka zitatu.
Israeli
Asayansi aku Israeli adauza dziko lapansi kuti nsomba yagolide imakumbukira zomwe zidachitika (osachepera) miyezi 5 yapitayo. Nsombazo zidadyetsedwa mumtsinje wa aquarium, limodzi ndi nyimbo kudzera pama speaker apansi pamadzi.
Patatha mwezi umodzi, okonda nyimbo adamasulidwa kunyanja, koma adapitiliza kuyimba nyimbo zolengeza kuyambika kwa chakudya: nsomba momvera idasambira ndikumveka bwino.
Mwa njira, zoyesera zoyambirira zidatsimikizira kuti nsomba zagolide zimasiyanitsa olemba ndipo sizingasokoneze Stravinsky ndi Bach.
Northern Ireland
Zinakhazikitsidwa pano kuti nsomba zagolide zimakumbukira zowawa. Mwa kufanana ndi anzawo aku Japan, akatswiri aku Biology aku Northern Ireland adalimbikitsa okhala m'nyanjayi ndi magetsi ofooka ngati atasamukira kumalo oletsedwa.
Ofufuzawo apeza kuti nsombayi imakumbukira gawo lomwe idamva ululu ndipo siyisambira kumeneko kwa tsiku limodzi.
Canada
Yunivesite ya MacEwan idayika ma cichlids aku Africa m'nyanja yamadzi ndikudyetsa chakudya mdera limodzi masiku atatu. Kenako nsombazo zidasamutsidwa kupita kuchidebe china, chosiyana ndi mawonekedwe. Pambuyo masiku 12, adabwezedwa ku aquarium yoyamba ndipo adazindikira kuti ngakhale atapuma nthawi yayitali, nsombazi zimasonkhana m'mbali mwa nyanja yomwe amapatsidwa chakudya.
Anthu aku Canada adayankha kuti funso lomwe nsomba limakumbukira. M'malingaliro awo, cichlids amakumbukira, kuphatikiza malo odyetserako, kwa masiku osachepera 12.
Ndipo ... Australia
Wophunzira wazaka 15 waku Adelaide adayamba kukonzanso mphamvu zamaganizidwe za nsomba zagolide.
Rorau Stokes adatsitsa ma beacon apadera mu aquarium, ndipo atatha masekondi 13 adatsanulira chakudya m'malo ano. M'masiku oyambirira, anthu okhala m'nyanja ya aquarium amaganiza kwa mphindi, kenako ndikusambira mpaka pamalopo. Pambuyo pa masabata atatu ophunzitsidwa, anali pafupi ndi chizindikirocho pasanathe mphindi zisanu.
Chizindikirocho sichinapezeke mu aquarium masiku asanu ndi limodzi. Kumuwona tsiku lachisanu ndi chiwiri, nsombayo idalemba, kukhala pafupi patadutsa masekondi 4.4. Ntchito ya Stokes idawonetsa kuti nsombazo zimatha kukumbukira bwino.
Izi ndi zina zowonetsa zikuwonetsa kuti alendo aku aquarium atha:
- lembani nthawi yodyetsa;
- kumbukirani malo odyetserako ziweto;
- kusiyanitsa wopezera chakudya ndi anthu ena;
- mvetsetsani "okhala nawo" atsopano komanso akale mu aquarium;
- kumbukirani malingaliro olakwika ndikuwapewa;
- chitani ndi mawu ndikusiyanitsa pakati pawo.
Chidule - nsomba zambiri, monga anthu, zimakumbukira zochitika zazikulu m'miyoyo yawo kwanthawi yayitali. Ndipo kafukufuku watsopano wothandizira chiphunzitsochi sachedwa kubwera.
