Iimvakalelo, Isizathu, Ukwenza Isinqumo Kungathi Kuchaphazelekayo
Ngaphandle kwezinto eziqhelekileyo, ukuzonwabisa ngokubambisa inambuzane ngabantu abancinci kunokuchaphazela imimandla yengqondo echaphazelekayo kwimvakalelo, ukukhuthaza nokuthatha izigqibo kwaye izazinzulu zithi okokuqala ngqa banobubungqina bokufakazela.
Imifanekiso ye-MRI yobuchopho abaneminyaka eyi-18 ukuya kweyama-25 ibonisa ukuba ukutshaya ukhula kutshintsha ubungakanani, ukuma kunye nobuxininisa beengingqi ezibini zengqondo.
Ukwahluka kobuchopho obungalinganiyo xa kuthelekiswa nabangewokubhema buhambelana ngokuthe ngqo kwindlela inambuzane edla ngayo, abaphandi bafumene.
Izifundo ezidlulileyo zabaTshayayo abakhulu
Kukho ezininzi izifundo ezidlulileyo eziye zaxhamla ukusebenzisa i-marijuko ukuphazamiseka ekukhuthazeni, ingqwalasela, ukufunda kunye nememori. Uphando lufumene ukuba ukusebenzisa ixesha elide lokusebenzisa i-marijuana kunokuthintela ukukhuthazwa . Olunye uphando luye lwaxhamla usetyenziso lwe-mariju ekufundeni okungaziphathi kakuhle kunye nezakhono zentlalo .
Olunye uphando lufumene ukuba ukutshaya inambuzane kungonakalisa amandla okugcina ingqalelo kwaye olunye uphando lubonise ukuba ukusetyenziswa kwentsangu yamanzi kungabangela ukuphazamiseka kwengqondo engabonakaliyo kulabo abaqala ukutshaya i-marijuana kamva ebomini.
Nangona abantu ababhemayo abathintekayo
Kodwa ininzi, ukuba ayinabo bonke, kwezo zifundo zibandakanyeka isifo esingapheliyo, isisindo esinobunzima. Uphononongo olutshanje, olupapashwe kwiNcwadi ye-Neuroscience , ngowokuqala ukudibanisa ngokungaqhelekanga, i-marijuana isebenzisana nemiphumo emibi engqondweni.
Nangona ubungakanani beesampula zolu cwaningo luyingcinci - izifundo ezingama-40 kuphela, ezibandakanya ama-20 angewona-marijuana asebenzisa ukulawula - ulwahluko kwiibinzana zamaqela amabini luphawulekayo, ababhali babika.
Abaphengululi kwiYunivesithi yaseNorwesterntern naseMassachusetts General Hospital / iHarvard Medical School basebenzisa i-imagination magnetic imagination ukuthelekisa ubuncinci be-20 abatsha abavakalisa ukutshaya i-mariju ubuncinane kanye ngeveki kunye nabanye abangama-20 ubudala abaneminyaka eyi-18-25 abavakalisa ingqalelo kwimbali ye-marijuana.
Okuqhelekileyo, Abasebenzisi bokuzonwabisa kuphela
Iingcali zenzululwazi zilinganisa umthamo, imilo kunye nobuxhakaxhaka bezinto ezimpunga kwi-nucleus accumbens kunye ne-amygdala. I-nucleus accumbens ibandakanyeka ekusebenziseni umvuzo kunye nokwenza izigqibo, ngelixa i-amygdala idibaniswa nemvakalelo.
Abathathi-nxaxheba bahlolwe ukuba bafumane ukuba akukho namnye oxhomekeke kwi-marijuana okanye nayiphina imichiza kwaye akukho namnye wabachaphazelekayo owake waphatha kakubi naziphi na ezinye iziyobisi.
Abo babasebenzisa inambuzane baceliwe ukuba baqikelele ukusetyenziswa kwabo inambuzane kwinyanga e-ezintathu, kubandakanywa nenani leentsuku abavuthayo kunye nesixa sesilwanyana esisetyenziswe ngalunye suku.
Ubukhulu, Uhlobo kunye nobuninzi beTshintsho
Abaphandi bafumanisa ukuba abaninzi abasebenzisi begciwane baxela ukuba bachithe, ukugqithisa okungaphezulu kwe-nucleus accumbens kunye ne-amygdala kwimifanekiso ye-MRI. Ubume kunye nobuninzi beemimandla zombini yengqondo behluke phakathi kwabasebenzisi be-mariju kunye nabangewona abasebenzisi.
Ubunongo balabo bavutha umhlanganiso omnye ngosuku okanye abo babopha kanye kuphela ngeveki batshintshiwe.
Uvavanyo oluphakamisa umngeni onzima kwingcamango yokuba ukusetyenziswa kwegciwane elingasetyenziswayo akuhambelani nemiphumo embi, "kusho uHans Breiter, MD. "Abanye bala bantu basebenzisa i-marijuana kuphela ukuba baphakame phezulu kanye okanye kabini ngeveki,"
Ukusetyenziswa ngeNkcitho rhoqo kunokubangela iingxaki
"Abantu bacinga ukuba ukuzonwabisa okuncinci akufanele kubangele ingxaki, ukuba umntu wenza okulungileyo ngomsebenzi okanye kwisikolo. Idatha yethu ngokuthe ngqo ithi akusiyo imeko," kusho uBreiter kwi-news release.
Abanye abaphandi, abangabandakanyekanga kwi-Massachusetts General, bavuma ukuba ukufumana utshintsho kwiibhinqa zabasebenzisi be-marijuana abangaqhelekanga kwakumangalisa.
"Olu cwaningo lubonisa ukuba ukusetyenziswa kwe-marijuana yokuzonwabisa ngokukhawuleza kunokulula kwenza ukuba utshintsho lwamaqondo olusengqondweni," watsho uCarl Lupica, PhD, weSizwe soMhlaba ekuDlanzisweni kweziyobisi. "Ezi ngqwalaselo zibaluleke kakhulu kuba izifundo zangaphambili zijolise ngokukodwa kwiibhokhwe zentsholongwane enobumnyama, kwaye ziye zazingalibalali ubuchopho babasebenzisi abangaqhelekanga."
Uphando lwaxhaswa yiNational Institute of Drug Abuse, i-Ofisi yoMgaqo-nkqubo weSizwe woLwaphulo-mthetho, iZiko loVavanyo loPhando lweeNkcazo, kunye neNational Institute of Neurological Disorders and Stroke.
