Amaphuzu abalulekile

• Ucwaningo olusha luthola ukuthi labo ama-amygdalas abo abambelela emizweni engemihle isikhathi eside babika imizwa engemihle kakhulu futhi baba nokuphila okuphansi kwengqondo ngokuhamba kwesikhathi.
• Ukubambelela ezintweni ezingezinhle nakho kunomthelela ngoba kuthinta ukuzihlola komuntu ngenhlalakahle yakhe.
• Ukuthola izindlela zokuvimbela izingqinamba ezincane ekukuhliseni, ngakho-ke, kungaholela enhlalakahleni enkulu ngokomzwelo.

Ngabe uvame ukubambelela kwimizwa engemihle lapho okuthile (noma othile) okucasulayo kungena ngaphansi kwesikhumba sakho? Njengoba ama-clichés ehamba: Ngabe ujwayele "ukujuluka ngezinto ezincane" futhi "ukhalele ngobisi oluchithekile"? Noma yenza "Grrr!" izikhathi nokucasuka okuncane okutholayo ngenkathi uqhubeka nempilo yansuku zonke kuvame ukuncipha ngaphambi kokuthile okungalungile kukufake esimweni esibi?

Ucwaningo olusha luphakamisa ukuthi abantu abaseminyakeni yokuphila kwasemuva abanekhono le-happy-go-lucky lokuvumela imizwa engemihle isuke emhlane wabo kungenzeka ukuthi bakha ukwanda okuphezulu kwenhlalakahle yengqondo yesikhathi eside (PWB) ngokwaphula umjikelezo "wokuphikelela kwe-amygdala" lokho kubonakala kuhambisana nokuhlala kokunganaki.

Ngokusho kwabaphenyi, ukuthi ubuchopho bomuntu (ikakhulukazi isifunda i-amygdala kwesobunxele) buhlola kanjani izinto ezingezinhle ezidlulayo — kungaba ngokubambelela kokunganaki noma ukukuyeka — kungaba nomthelela ohlala njalo ku-PWB. Lolu cwaningo olubukeziwe kontanga (Puccetti et al., 2021) lwashicilelwa ngoMashi 22 ku Ijenali yeNeuroscience .

Umbhali wokuqala uNikki Puccetti nombhali omkhulu u-Aaron Heller wase-University of Miami benze lolu cwaningo nozakwabo base-University of Wisconsin-Madison's Center for Healthy Minds, Cornell University, Penn State, kanye ne-University of Reading. Ngaphezu kokuba umsizi kaprofesa wesayensi yezengqondo e-UMiami, uHeller ungudokotela wezengqondo, umthinteli wezinzwa, kanye nomphenyi omkhulu weManatee Lab.

"Iningi locwaningo lomuntu lwe-neuroscience lubheka ukuthi ubuchopho busabela kanjani ngokuqinile ezintweni ezingezinhle, hhayi ukuthi ingqondo ibambelela kangakanani ekugqugquzelweni," kusho uHeller ngesikhathi ekhipha izindaba. "Sibheke i-spillover-indlela umbala ongokomzwelo womcimbi ugelezela ngayo kwezinye izinto ezenzekayo."

Isinyathelo sokuqala salolu cwaningo lwemikhakha ehlukene kwakuwukuhlaziya idatha esuselwa kuhlu lwemibuzo eqoqwe kusuka kwabangu-52 kwezinkulungwane zabantu ababambe iqhaza esifundweni sesikhathi eside se- "Midlife e-United States" (MIDUS) esaqala maphakathi nawo-1990.

Okwesibili, ngesikhathi sokushaya ucingo ebusuku izinsuku eziyisishiyagalombili zilandelana, abacwaningi bacela ngamunye wababambiqhaza bezifundo ezingama-52 ukuthi babike izehlakalo ezithile ezicindezelayo (isb. Ukuminyana kwezimoto, ikhofi elichithekile, izinkinga zekhompyutha) ababhekane nakho ngalolo suku kanye namandla abo noma imizwa engemihle usuku lonke.

Okwesithathu, cishe cishe isonto lalezi zingcingo zobusuku ngabunye, isifundo ngasinye senziwa ukuskena kobuchopho be-fMRI "okwakulinganisa futhi kwenza imephu yomsebenzi wabo wobuchopho njengoba babebuka futhi bakala izithombe ezingama-60 ezinhle nezingu-60 ezingezinhle, ezifakwe nezithombe ezingama-60 ubuso obungathathi hlangothi. "

Okokugcina, abacwaningi baqhathanisa yonke idatha evela emibuzweni yomhlanganyeli ngamunye ye-MIDUS, imininingwane yakhe yasebusuku "yedayari yocingo", kanye neuroimages kusuka kuskena sobuchopho se-fMRI.

Kuthathwe ndawonye, ​​okutholakele ocwaningweni kuphakamisa ukuthi "abantu abane-amygdala yesobunxele ebambelele ezintweni ezingezinhle okwemizuzwana embalwa babenamathuba amaningi okuthi babike imizwa emihle nemincane kakhulu ezimpilweni zabo zansuku zonke-okuchithekele enhlalakahleni ehlala isikhathi eside ngokuhamba kwesikhathi. "

"Enye yezindlela zokucabanga ngakho isikhathi eside lapho ubuchopho bakho bubambelela emcimbini ongemuhle, noma isikhuthazi, lapho ungazibiki uthokozile," uPuccetti, oyi-Ph.D. umuntu obengenele ukhetho eMnyangweni Wezengqondo UMiami, kusho lokhu kukhishwa kwezindaba. "Ngokuyinhloko, sithole ukuthi ukuphikelela kobuchopho bomuntu ekubambeleleni kwisikhuthazi esingesihle yilokho okubikezela imizwa engemihle futhi engemihle yemizwa yansuku zonke. Lokho-ke, kubikezela ukuthi bacabanga ukuthi benza kahle kanjani empilweni yabo."

"Abantu abakhombisa amaphethini wokwenza kusebenze okuphikelelayo ku-amygdala yangakwesobunxele kwisikhuthazi esiphikisayo babike ukuthikamezeka okuhle nokungajwayelekile kaningi (NA) empilweni yansuku zonke," kuchaza abalobi. "Ngaphezu kwalokho, ukuthinteka okuhle kwansuku zonke (PA) kusebenze njengesixhumanisi esingaqondile phakathi kokuphikelela kwesokunxele kwe-amygdala ne-PWB. Le miphumela icacisa ukuxhumana okubalulekile phakathi kokwehluka komuntu ngamunye ekusebenzeni kobuchopho, okuhlangenwe nakho kwansuku zonke kokuthinteka nenhlalakahle."

Ungavumeli Izinto Ezincane Zikudicilele Phansi

"Kungenzeka ukuthi kubantu abanokuphikelela okukhulu kwe-amygdala, izikhathi ezingezinhle zingakhuliswa noma zandiswe ngokufaka izikhathi ezingahlobene ezilandela ukulinganisa okungekuhle," kubhala abalobi. "Lesi sixhumanisi sokuziphatha kobuchopho phakathi kokuphikelela kwesokunxele kwe-amygdala kanye nomthelela wansuku zonke kungazisa ukuqonda kwethu kokuhlolwa okuhlala isikhathi eside, okuhlala isikhathi eside kwenhlalakahle."

Ukuphikelela okuncane kwe-amygdala kulandela imicimbi emibi empilweni yansuku zonke kungahle kubikezele ukuba nomthelela omkhulu, umthelela omuhle empilweni yansuku zonke, okungathi, ngokuhamba kwesikhathi, kudale ukwenyuka okuphezulu kwenhlalakahle yengqondo isikhathi eside. "Ngakho-ke, okuhlangenwe nakho kwansuku zonke kokuthintekayo kuqukethe isinyathelo esithembisayo esiphakathi esixhumanisa ukungafani ngakunye kwe-neural dynamics nezahlulelo eziyinkimbinkimbi zenhlalakahle yengqondo," kuphetha abalobi.
