uhlelo lokuvuza

Umvuzo System

Ukuze siqonde ukuthi kungani siqhutshwa ukudla okuhlwabusayo, ukuthinta ngothando, isifiso sobulili, utshwala, i-heroin, izithombe zobulili ezingcolile, ushokoledi, ukugembula, ezokuxhumana nabantu noma ezitolo ze-intanethi, sidinga ukwazi ngesistimu yokuvuza.

The uhlelo lokuvuza ingenye yezinhlelo ezibaluleke kakhulu ebuchosheni. Lokhu kuholela ekuziphatheni kwethu ekusebenziseni izinto ezijabulisayo ezifana nokudla, ubulili, utshwala, njll. Futhi kusisusa kude nobuhlungu (ukuxabana, umsebenzi wesikole, njll) okudinga amandla noma umzamo omkhulu. Yilapho sizizwa khona imizwa futhi senze leyo mizwelo ukuqala noma ukuyeka isenzo. Iqukethe iqembu lezakhi zobuchopho engxenyeni yobuchopho. Balinganisa ukuthi bangaziphindaphindi yini ukuziphatha futhi benze umkhuba. Umvuzo yisisusa esenza ukuba nesifiso sokushintsha ukuziphatha. Imivuzo ngokuvamile isebenza njengabaqinisa. Okusho ukuthi, basenza siphinde senze ukuziphatha esikubonayo (ngokungazi) njengento enhle ekusindeni kwethu, ngisho nalapho bengekho. Ukuthakazelisa kungumvuzo ongcono noma ukugqugquzela kunokuba ubuhlungu bokugqugquzela ukuziphatha. Isanqante ingcono kunenduku njll.

I-Striatum

Ephakathi nendawo yohlelo lokuvuza yiyona striatum. Yisifunda somqondo oveza imizwa yomvuzo noma injabulo. Ngokusebenzayo, i-striatum iqondisa izici eziningi zokucabanga ezisisiza senze isinqumo. Lokhu kufaka phakathi ukuhlela nokuhamba kwesenzo, ukugqugquzela, ukuqinisa, nokuvuza umqondo. Yilapho ubuchopho bunciphisa inani le-stimulus ku-nanosecond, ukuthumela 'hamba khona' noma 'ukuyeka' izimpawu. Le ngxenye yobuchopho ishintsha kakhulu ngenxa yendlela yokulutha noma isifo sokusebenzisa kabi izidakamizwa. Imikhuba eye yaba yimijondolo ejulile yindlela yokufunda 'kwezemvelo,' okuwukufunda okungenakulawula.

Lesi yisikhathi esifushane se-TED enkulumweni Umculi Wokuthakazelisa.

Indima Ye-Dopamine

Iyini indima ye-dopamine? I-dopamine yinkinga ye-neurochemical ebangela umsebenzi ebuchosheni. Yilokho uhlelo lomvuzo olusebenzayo. Inemisebenzi ehlukahlukene. I-Dopamine yi-'-get-get-it' neurochemical eyasishukumisela ukuba sikhuthaze noma sibe nemivuzo kanye nokuziphatha esikudingayo ukuze sisinde. Izibonelo kukhona ukudla, ubulili, ukubopha, ukugwema ubuhlungu njll. Futhi kuyisignali esenza sishukumise. Isibonelo, abantu abanezifo zikaPasinson abazicubungula i-dopamine eyanele. Lokhu kubonisa njengokunyakaza okunamandla. Iziphephelo eziphindaphindiwe ze-dopamine 'ziqinisa' izindlela ze-neural ukuze senze ukufuna ukuphinda ukuziphatha. Kuyinto ebalulekile ekufundeni kwethu konke.

Ilinganiswa ngokucophelela ebuchosheni. Inkolelo enkulu mayelana nendima ye-dopamine yiyona ukugqugquzela i-theory. Kungenxa yokufuna, hhayi ukuthanda. Ukuzizwa injabulo ngokwayo kuvela kuma-opioid yemvelo ebuchosheni obangela umuzwa wokujabula noma ophakeme. I-dopamine nama-opioid isebenza ndawonye. Abantu abane-schizophrenia bavame ukungena ngokweqile kwe-dopamine futhi lokhu kungabangela iziphepho ezingokwengqondo nemicabango ejulile. Cabanga nge-Goldilocks. Ukulinganisela. Ukuzidla ngokudla, utshwala, izidakamizwa, i-porn njll kuqinisa lezo zindlela futhi kungaholela ekuluthweni kwabanye.

I-Dopamine ne-Pleasure

Inani le-dopamine elikhishwe ubuchopho ngaphambi kokuziphatha lilingana nokukwazi kwalo ukuhlinzeka injabulo. Uma sithola injabulo ngento noma umsebenzi, imemori eyakhiwe isho ukuthi silindele ukuthi iyophinde ibe mnandi futhi. Uma isikhuthazo siphula ukulindela kwethu- siyinto ejabulisayo noma engathandeki kakhulu - sizokhiqiza i-dopamine engaphansi kakhulu esikhathini esizayo lapho sihlangana khona nesisusa. Izidakamizwa ziqeda uhlelo lokuvuza futhi zikhiqize amazinga aphezulu we-dopamine nama-opioids ekuqaleni. Ngemuva kwesikhathi ubuchopho bujwayele ukuvuselela, ngakho-ke kudinga ukuthuthukiswa kwe-dopamine ukuze uthole phezulu. Ngezidakamizwa, umsebenzisi udinga okufanayo, kepha nge-porn njengendlela yokuvuselela, ubuchopho badinga ukusha, okuhlukile futhi okwesabekayo noma okumangazayo ukuthola eliphezulu.

Umsebenzisi uhlala ehlaziya imemori kanye nesipiliyoni se-euphoric ephezulu, kodwa ngokuvamile uphelelwa yisikhathi. Angikwazi ukuthola ... .satisfaction. Umsebenzisi futhi, ngemuva kwesikhathi, angase 'adinge' i-porno noma utshwala noma ugwayi, ukuze ahlale ekhanda lobuhlungu obubangelwa i-dopamine ephansi kanye nezimpawu zokuqeda ukucindezeleka. Ngakho-ke umjikelezo ononya wokuthembela. Kumuntu onesisetshenziswa sokusebenzisa izinto noma ukuxhomeka kokuziphatha, 'isifiso' sokusebenzisa, esibangelwa ukushintsha amazinga e-dopamine, angase abe nomuzwa wokuthi 'ukuphila noma ukufa' kunesidingo sokusinda futhi kuholele ekuthatheni izinqumo ezimbi kakhulu ukuze amise ubuhlungu.

Source Main of Dopamine

Umthombo oyinhloko we-dopamine kule ndawo yendawo yobuchopho (striatum) ikhiqizwa endaweni ye-ventral tegmental (VTA). I-ke iya kwi-nucleus accumbens (NAcc), isikhungo somvuzo, ngokuphendula / ukubona / ukulindela umvuzo, ukulayisha i-trigger ilungele isenzo. Isenzo esilandelayo - umsebenzi wezimoto / ukunyakaza, osebenze isignali yokumnandi 'hamba ukuwuthola,' noma isignali yokuvimbela, njengokuthi 'ukumisa', kuyonqunywa isignali esivela ku-prefrontal cortex uma isuqedile ulwazi. Uma i-dopamine engaphezulu ikhona esikhungweni somvuzo, ukukhushulwa kunjengoba umvuzo. Abantu abanezinkinga zokuziphatha ezingaphandle kokulawula, noma izidakamizwa, bakhiqiza isibonakaliso esibuthakathaka kakhulu kusuka ku-prefrontal cortex ukuvimbela isifiso noma isenzo esiphuthumayo.
