Ngezinsuku ezishisa kakhulu zasehlobo, singase sizunywe ubuthongo phakathi nosuku. Kwezinye izingxenye zomhlaba, kuwumkhuba wokuthatha isihlwathi esifushane futhi uvale amabhizinisi phakathi namahora ashisa kakhulu osuku. Kuvela ukuthi i-biology, hhayi nje isiko, ingaba ngemuva kwayo.
Izinga lokushisa lithinta ubude besikhathi sokuziphatha komuntu, kusukela kumazinga okudla nawomsebenzi kuye emijikelezweni yokulala nokuvuka. Singase sikuthole kunzima kakhulu ukulala ebusuku ehlobo futhi kungase kuthathe isikhathi eside ukuvuka ekuseni lapho kupholile. Kodwa ukuxhumana phakathi kwama-sensory neurons nama-neuron alawula lo mjikelezo akuqondakali ngokugcwele.
Izazi ze-Neurobiologists ze Inyuvesi yaseNorthwestern Sebeyitholile imikhondo yokuthi kwenzakalani. Ocwaningweni olusha, abacwaningi bathola ukuthi izimpukane zezithelo zihlelwa kusengaphambili ukuthi zilale phakathi nosuku. Lezi zinambuzane ziyimodeli enhle kakhulu yokufunda imibuzo emikhulu njengokuthi "kungani silala?" nokuthi “ukulala kusizani ebuchosheni?”, njengoba bengazami ukushintsha umzwelo wemvelo ngendlela efanayo neyabantu.
Isihlwathi siba side ehlobo
Abacwaningi bathole ukuthi ama-neurons obuchopho athola ulwazi mayelana nokushisa ayingxenye yesistimu enkulu elawula ukulala. Lapho isifunda esishisayo, esihamba ngokuhambisana nesiyingi esibandayo, sisebenza, amaseli akhuthaza ukulala kwasemini ahlala isikhathi eside. Lokhu kubangela ukwanda kokulala kwasemini okugcina izimpukane ziqhele endaweni eshisa kakhulu yosuku.
Ucwaningo lwenziwe lwaba yimpumelelo uhlelo lweminyaka eyi-10 olwakhiqiza imephu yokuqala ephelele yokuxhumana kwemizwa esilwaneni (impukane), ebizwa ngokuthi. uxhumano. Nge-connectome, abacwaningi banokufinyelela ohlelweni lwekhompyutha olubatshela konke ukuxhumana okungenzeka kobuchopho kwengqamuzana ngalinye lobuchopho bempukane obuyi-100.000. Kodwa-ke, ngisho nangalo mephu womgwaqo onemininingwane, abacwaningi basadinga ukuthola ukuthi ulwazi olusebuchosheni luthola kanjani ukusuka endaweni A kuye ku-B.
Amasekhethi ahlukene wamazinga okushisa ashisayo nabandayo anengqondo ngoba amazinga okushisa angaba nemiphumela ehluke kakhulu ku-physiology nokuziphatha. Lokhu kwehlukana kungase futhi kubonise izinqubo zokuziphendukela kwemvelo ezisuselwe kumjikelezo wokushisa nokubanda womhlaba.
kungaba biological
Okulandelayo, ithimba locwaningo lithemba ukuthola izinhloso ezifanayo zesifunda esishisayo nesibandayo, ukuthola ukuthi ngayinye ingaba nomthelela kanjani ekulalelweni.
Bahlonze i-neuron engase ibe isayithi yokuhlanganisa yemithelela yamazinga okushisa ashisayo nabandayo ebuthongweni kanye nomsebenzi ezimpukane. Lokhu kungaba yisiqalo sezifundo ezilandelayo ezithokozisayo. Ithimba linentshisekelo yokubheka imiphumela yesikhathi eside yezinga lokushisa ekuziphatheni nasekuziphatheni komzimba ukuze liqonde umthelela wokufudumala kwembulunga yonke, libheke ukuthi izinhlobo zezilwane eziguquguqukayo zingashintsha kanjani.
Abantu bangase bakhethe ukulala ntambama ngosuku olushisayo, futhi kwezinye izingxenye zomhlaba lokhu kuwumkhuba wamasiko, kodwa yini oyikhethayo nokuthi yini ehlelwe kuwe? Kunjalo, akusiwona fly isiko, ngakho empeleni kungaba khona indlela yezinto eziphilayo isici esiyisisekelo esinamandla kakhulu esinganakwa kubantu.
