Uphononongo olutsha lwandisa ngakumbi kwimiphumo yekofu. Impembelelo yekofu, kwaye ngokukodwa i-caffeine, kwi-physiology yethu kunye ne-psyche yethu iyahlolwa. Ukuthelekisa kufumene umehluko phakathi kwekhofi kunye nokutya kwe-caffeine ekuseni.
Ikhofi ithandwa kungekuphela nje ngenxa yokunambitheka kwayo, kodwa kunye nefuthe layo elikhuthazayo - inceda ngokukhawuleza ukuvuswa kunye nokugxininiswa okungcono, kunye neminye imiphumo emihle.
Uninzi lweempembelelo zekofu zibangelwa yinto enye kwisiselo - i-caffeine. Inempembelelo eqinisekisiweyo kwiinkqubo ze-biochemical emzimbeni, ukwandisa ukukhululwa kwe-dopamine kunye nokuphucula imemori. I-caffeine ineempembelelo kungekuphela kwi-biochemistry yethu, kodwa nakwingqondo yethu.
Iphepha lezenzululwazi lijonge umahluko phakathi kokusela ikofu kunye nokuthatha isithako se-caffeine ngokwahlukileyo. Uphononongo lwe-MRI lwenziwe olubonisa ngokuthe ngqo iziphumo kwingqondo. Iziphumo zibonisa ukuba zombini ikofu kunye ne-caffeine zinciphisa uxhulumaniso kwisekethe ethile engqondweni ebizwa ngokuba yi-DMN, imfutshane kuthungelwano lwemowudi engagqibekanga. Isekethe ye-DMN isebenza xa ingqondo yethu "ibhadula" kwaye yenza iinkqubo ezininzi ezinokubizwa ngokuba yi-subconscious.
Ukudityaniswa kwesekethe ye-DMN ebuthongweni bethu kukho - uninzi lwemisebenzi esiyenzayo kwangethuba ekuseni kwimeko yokulala yenziwa ngaphandle kwenjongo enolwazi, njengokungathi sinokuhamba nge-autopilot ngokusebenzisa inkqubo esiyimisile. Ngethuba ikhofi yasekuseni idliwe, umsebenzi kwisekethe ye-DMN iyancitshiswa. Umsebenzi oncitshisiweyo ufana nomqondiso kwingqondo yethu ukulungiselela ukunikela ingqalelo kwindawo esingqongileyo kunye neengcinga zethu.
Iziphumo kwisekethe ye-DMN zibangelwa yi-caffeine kwikofu, kodwa ayisiyiyo kuphela isithako kwisiselo. Iqulethe izinto ezifana ne-cafestol kunye ne-kahweol, ezinokusebenzisana ne-receptors kwingqondo ngeendlela ezinceda ukwandisa amanqanaba amandla okanye ukuphucula isimo sengqondo.
Uphononongo luhlola isithethe sokusela ikofu. Kukho ezinye iziphumo zokusela ikofu ezinokuthi zibangelwa yimpembelelo ye-placebo esizenzele yona - uhlobo oluthile lwenkolelo yokuba ikofu isenza sizive bhetele kusasa ingaba ngundoqo kwimpembelelo yokwenene yokuvuselela ngaphandle kwe-caffeine okanye ezinye izinto.
