Jijiya Kwayoyin to regenerate?

A cikin mutane, akwai fiye da ɗaya da ɗari biliyan neurons.

A baya can da aka zaci cewa jijiya Kwayoyin ba regenerate. Duk da haka, wannan tabbatarwa da aka karyata ta zamani magani. Duk da rashi na da ikon zuwa raba, jijiya Kwayoyin to regenerate da kuma ci gaba a cikin kwakwalwa, ko da ya fara tasawa. Bugu da kari, neurons iya regenerate batattu appendages da kuma sadarwa tare da sauran Kwayoyin.

A mafi muhimmanci tari na jijiya Kwayoyin dake a cikin kwakwalwa. Saboda da kashe-harbe suna kafa yawa lambobi da ke makwabtaka da neurons.

A juyayi tsarin a cikin lafiya jiki ne mai kyau-ta shirya tsarin. Duk da haka, idan a cikin hadaddun sarkar na daya daga cikin links ba su cika aiki, na iya zama fama da dukan jiki. Tsanani kwakwalwa rauni da bi Parkinson ta cuta, bugun jini, Alzheimer ta cutar gubar zuwa kara asarar neurons. Shekaru da dama, masana kimiyya suna kokarin amsa wannan tambaya na yadda jijiya Kwayoyin to regenerate.

Yau an san cewa ƙarni na neurons a cikin balagaggu dabbobi masu shayarwa kwakwalwa za a iya za'ayi amfani da musamman kara Kwayoyin (abin da ake kira neuronal). A wannan lokaci gano cewa, da jijiya Kwayoyin suna gano a cikin subventricular yankin, hippocampus (dentate gyrus), da kuma cerebellar bawo. A karshe sashe ne alama mafi tsanani neurogenesis. A cerebellum ne da hannu a nemowa da kuma rike bayanai game da basira da sarrafa kansa kuma sõmamme. Alal misali, razuchivaya dance motsi, mutane hankali daina tunani game da su, yin su ta atomatik.

A mafi m masana kimiyya imani farfadowa daga neurons a dentate gyrus. A wannan yankin, akwai haihuwar motsin zuciyarmu, ajiya da kuma aiki na sarari bayanai. Masana kimiyya sun ba tukuna gudanar ya kawo karshen fahimtar yadda sabuwar kafa neurons shafi tunanin riga ya kafa, da kuma yadda ya aikata su hulda da balagagge neurons a cikin wannan kwakwalwa yankin.

Masana kimiyya lura da cewa jijiya Kwayoyin suna mayar a annan yankunan, wanda ke da alhakin kai tsaye rayuwa a cikin jiki jirgin sama: fuskantarwa a sarari, da wari, da samuwar motor memory. Samuwar m tunani ke aiki a wani matasa shekaru, a lokacin da wani kwakwalwa girma. A wannan neurogenesis ake dangantawa da duk zones. Bayan kai ƙarfinsa ci gaban fahimi ayyuka ne da za'ayi ta gyara na lambobi tsakanin neurons, amma ba saboda da samuwar sabuwar Kwayoyin.

Ya kamata a lura da cewa masana kimiyya ci gaba da bincika a baya ba a sani ba foci na neurogenesis, ko da yake quite 'yan a samu nasara. Wannan shugabanci yana dacewar ba kawai a cikin na asali kimiyya amma kuma amfani da gudanar da bincike.
