Ese rimwe na rimwe wibagirwa mu buryo butunguranye aho ushyira imfunguzo zawe cyangwa izina ry'inshuti yawe? Cyangwa wibuka ikintu cyabaye mu myaka yashize nk'aho ari ejo? Inyuma y'iki kintu gitangaje cyitwa kwibuka hari igice gito ariko gikomeye cyane cy'ubwonko bwacu. Nubwo utari inzobere mu by'imitsi, ushobora kuba warumvise iri zina - ni ' Hippocampus '. Uyu munsi turaganira kuri iki gice gitangaje, uko gikora, n'akamaro kacyo ku buzima bwacu.
Mu magambo make, iyi hippocampus ni iki?
Hippocampus ni igice cy’urwego rw’imyanya mu bwonko bwacu. Ubu buryo bufitanye isano rya hafi n’ubwiyibuke bwacu, kwiga, n’amarangamutima . Akazi ka hippocampus ni ugufata kwibuka by’igihe gito no kugufasha kubikwa mu bindi bice by’ubwonko nk’iby’igihe kirekire. Ni nk’umuntu uri mu isomero afata ibitabo bishya, akabitondekanya, akabishyira ku bubiko buhoraho.
Izina 'hippocampus' rikomoka ku ijambo ry'Ikigiriki risobanura 'seahorse'. Ibi biterwa nuko uru rugingo rumeze nk'ifarashi yo mu nyanja. Twese dufite hippocampi ebyiri nk'izo mu bwonko bwacu, imwe kuri buri ruhande rw'ubwonko. Iki gice ni kimwe mu bice by'ubwonko byigwa cyane n'abahanga kuko gifitanye isano n'indwara nyinshi zo mu bwonko n'indwara.
Ni iki kibera kuri hippocampus?
Mbere na mbere, abashakashatsi batekerezaga ko hippocampus ifitanye isano n'uburyo bwo kumva impumuro (olfaction). Ariko nyuma byaje kugaragara ko akazi kayo k'ingenzi ari imirimo ijyanye no kwibuka. Ariko, ikoresha amakuru aturuka mu byumviro byacu bitanu (kubona, kumva, guhumurirwa, uburyohe, gukoraho) kugira ngo ikore kwibuka.
Kubera ko kwibuka ari ingenzi hafi ya byose dukora, hippocampus ni ingenzi mu buzima bwacu bwa buri munsi. Kubera imikorere yayo igoye, ishobora "kuvuga" cyangwa guhuza n'ibindi bice byinshi by'ubwonko.
Reka turebe imbonerahamwe iri hepfo kugira ngo turebe imirimo y'ingenzi ya hippocampus.
| Imikorere y'ingenzi | Ibisobanuro byoroshye |
|---|---|
| Ibitekerezo by'Urwibutso | Bigufasha kwibuka amakuru nk'izina ry'umuntu, itariki, isaha n'aho yaherereye. Urugero, bigufasha kwibuka ako kanya ibintu nko aho wahurira n'inshuti yawe n'inomero yayo yo mu rugo. |
| Guhindura ububiko bw'igihe gito mu bubiko bw'igihe kirekire | Bifasha kubika ibintu mu bwonko burundu, urugero nk'ikintu wize uyu munsi cyangwa izina ry'umuntu uherutse guhura. Gusinzira ni ingenzi cyane muri iki gikorwa. Niyo mpamvu twibagirwa ibintu mu minsi tudasinzira neza. |
| Kwibuka ahantu n'icyerekezo (Spatial Navigation) | Bigufasha kwibuka inzira zo kugera ahantu runaka. Tekereza, iyo uvuye mu rugo ujya mu iduka buri munsi, wibuka inzira ukoresheje iyi hippocampus. Ni nk'aho 'Google Map' iri mu mutwe wawe. |
Hippocampus iri he mu bwonko?
Hippocampus iherereye mu gice cy'ubwonko kiri hejuru y'amatwi yawe. Iki ni cyo gice gifasha kubika kwibuka n'amarangamutima .
Igitangaje ni uko, bitandukanye n'ibindi bice byinshi by'umubiri wacu, hippocampus ishobora guhinduka no gukura uko igihe kigenda gihita. Iyi nzira yitwa neurogeneis. Ibi bivuze ko iyo twize ibintu bishya kandi tukagira ubunararibonye bushya, iki gice kirushaho gukomera.
Wamenya ute niba hari ikibazo kuri hippocampus?
Ibimenyetso by'imikorere mibi ya hippocampal akenshi bifitanye isano no kwibuka. Ni ibisanzwe kwibagirwa aho washyize imfunguzo zawe umunsi umwe cyangwa ibiri, cyangwa gushyira izina ry'umuntu mu mwanya wabyo. Ariko niba ufite kimwe cyangwa byinshi mu bimenyetso biri hepfo , ni byiza kureba muganga wawe kugira ngo amenye icyabiteye.
| Ibimenyetso byo kwitondera |
|---|
| - Gutakaza kwibuka by'igihe gito (urugero, kwibagirwa ikintu cyavuzwe mu minota mike ishize) |
| - Kugorwa n'icyerekezo n'aho biherereye (urugero: kuzimira nubwo haba mu nzira izwi cyane) |
| - Kugorwa no gukora ibintu bishya (nubwo ibintu bya kera byaba ari byiza) |
| - Kugorwa no kwibuka ibintu nk'amatariki, amasaha, amazina, n'ahantu |
Ni izihe ndwara zifata hippocampus?
Hari indwara nyinshi zishobora kwangiza hippocampus.
- Indwara ya Alzheimer: Nubwo iyi ndwara ifata ibice byinshi by'ubwonko, hippocampus ni yo ifatwa bwa mbere. Mu ntangiriro z'indwara ya Alzheimer, ingingo zo muri hippocampus ziragabanuka zigatangira kugabanuka. Niyo mpamvu ibimenyetso nko kwibagirwa amazina n'amasura, no kuyobera mu mihanda isanzwe bibaho.
- Indwara yo guhangayika nyuma y’ihungabana (PTSD): Iyi ndwara ishobora kugaragara ku bantu bamwe na bamwe nyuma yo guhura n’ikibazo gikomeye cy’ihungabana. Ishobora kuba irimo ibimenyetso nko kurota inzozi mbi, kwibuka ibintu bishya, no guhangayika cyane. Ubushakashatsi bumwe bwagaragaje ko ingano ya hippocampus igabanuka muri iyi ndwara. Nanone, iyo ubwenge bwacu budushishikariza kwirinda ahantu cyangwa umuntu twumva dutinya, hippocampus ni yo ituma twumva iyo mitekerereze. Ni ukugira ngo iturinde akaga.
- Indwara yo mu gice cy'inyuma cy'umubiri: Indwara yo mu gice cy'inyuma cy'umubiri ishobora kwangiza hippocampus. Iyo izi ndwara zibayeho igihe kirekire, hippocampus ishobora kugabanuka.
Ni gute wakora kugira ngo hippocampus yawe ikomeze kugira ubuzima bwiza?
Nubwo tudashobora gukora imyitozo ngororamubiri ya hippocampus nk'uko duterura ibiremereye kugira ngo twubake biceps, hari ibintu bike dushobora gukora kugira ngo twongere kwibuka kwacu no kugira iki gice cy'ingenzi kibe cyiza. Ushobora kandi gusaba muganga wawe inama zirambuye kuri ibi.
- Menya ibintu bishya mu buzima bwawe bwose: Kwiga ururimi rushya, igikoresho cya muzika, cyangwa ubundi buhanga ubwo aribwo bwose bituma ubwonko bwawe na hippocampus bikora.
- Koresha ibyumviro byinshi icyarimwe: Koresha ibyumviro byinshi mu gihe wiga ikintu. Tekereza uri kwiga guteka ifunguro rishya. Iyo wize ubyitegereje, ukabihumura, kandi ukabiryoha, ubyibuka neza.
- Koresha igenamigambi n'ingengabihe:Aho kwihangayikishwa n'ibintu bito, koresha igenamigambi, kalendari, na porogaramu za telefoni kugira ngo bigufashe kwibuka.
- Suzuma ibyo wize: Umaze kumenya ikintu, ongera ugisuzume mu minsi mike, icyumweru, cyangwa ukwezi. Ibi bifasha hippocampus kohereza amakuru mu kwibuka igihe kirekire.
- Gusinzira neza nijoro: Nkuko twabivuze mbere, gusinzira ni ingenzi kugira ngo kwibuka birusheho gukomera. Gerageza gusinzira neza nibura amasaha 7-8 ku munsi.
- Imyitozo ngororamubiri buri gihe: Imyitozo ngororamubiri yongera amaraso ajya mu bwonko, ibi bikaba ari ingirakamaro cyane ku buzima bwa hippocampus.
Ubutumwa bwo kujyana mu rugo
- Hippocampus ni igice cy'ubwonko bwacu gifite ishusho nk'iy' 'ifarashi yo mu nyanja', kikaba ari ingenzi mu kwibuka, kwiga no mu byiyumvo.
- Akamaro k'ingenzi k'ibi ni uguhindura kwibuka by'igihe gito mo kwibuka by'igihe kirekire. Gusinzira neza ni ingenzi kuri ibi.
- Hippocampus idufasha kandi kwibuka ahantu n'icyerekezo.
- Niba ufite ibimenyetso nko kugira ibibazo byo kwibuka bidashira cyangwa kugorana mu kwerekeza icyerekezo, bishobora kuba ikimenyetso cy'ikibazo cya hippocampus. Muri icyo gihe , menya neza ko wagiye kwa muganga.
- Ushobora gutuma hippocampus yawe ikomeza kugira ubuzima bwiza binyuze mu kwiga ibintu bishya, gusinzira neza, gukora imyitozo ngororamubiri no kugabanya stress.
