Singumlutha, ngempela ngokweqiniso, kolwazi
Kungani kunjalo? UJohn Coates ukhuluma ngalolu daba encwadini yakhe esanda kukhishwa “Ihora Phakathi Kwezinja Ne-Wolf. "
Imayelana ne-dopamine - i-neurotransmitter ecwaningwe kakhulu ekhiqizwe phezulu kwesiqu sobuchopho esikhomba izifunda zobuchopho ezilawula umvuzo nokunyakaza.
“Uma sithola ucezu oluthile lolwazi olubalulekile, noma senza isenzo esithile esithuthukisa impilo yethu nokuphila kwethu, njengokudla, ukuphuza, ukuya ocansini noma ukwenza imali enkulu, i-dopamine ikhishwa kulokho okubizwa ngokuthi izindlela zobumnandi zobuchopho, kusinikeza okuhlangenwe nakho okuvuzayo, nokujabulisayo. Empeleni ubuchopho bethu bubonakala buzazisa i-dopamine ngaphezu kokudla noma isiphuzo noma ucansi uqobo, ”kuchaza uCoates.
Kukhona izifiso eziqhutshwa yi-dopamine futhi. Izidakamizwa zokuzilibazisa, ngokwesibonelo, zikhohlisa ama-dopamine neurons ekunikezeni imivuzo yawo. Kepha akuzona ukuphela kwento ekwenza ulangazelele okuningi.
Coates ichaza:
“Yini enye ngaphandle kwezidakamizwa zokuhlukumeza engadala isifiso esiqhutshwa yi-dopamine? Uma i-dopamine ibhebhezela isifiso solwazi nomvuzo ongalindelekile, mhlawumbe futhi kusigcwalisa ngokulangazelela okuvuthayo.
“Mhlawumbe ilukuluku uqobo, isidingo sokwazi, luhlobo oluthile lokulutha, lusenza sigijimisane kuze kube sekupheleni kwenoveli enhle yemfihlakalo, noma sishayele ososayensi ukuthi basebenze ubusuku nemini baze bathole i-insulin, basho, noma banqume ukwakheka kwe-DNA, intuthuko yesayensi ibe yiyona nto eyinhloko yolwazi.
"Lapho kuqala iTheory of General Relativity ku-Einstein, kumele ukuthi waba nomama wayo yonke i-dopamine."
I-Dopamine ayenzi nje ukuthi sifune imininingwane engaphezulu. Kukhuphuka kakhulu lapho senza isenzo somzimba esiholela kumvuzo ongalindelekile, futhi lokhu kusenza sifune ukuphinda izenzo esizithathile ukufika kulelo qophelo, noma ukuthola izindlela ezintsha zokwenza. Ngakho-ke, sihlala njalo sifuna "amaphethini wokusesha" ahlukile njengoba sifuna ulwazi.
