Manzwiro, Kukurudzira, Chisarudzo Kuita Kunogona Kuitika
Kunyangwe kusashamwaridzana, kushandiswa kwekunakidza mbanje nevechidiki kunogona kukanganisa nzvimbo dzeuropi dzakabatanidzwa mune manzwiro, zvinokurudzira uye kuita zvisarudzo uye masayendisiti anoti panguva yekutanga ivo vane uchapupu hwokuratidza.
MRI mifananidzo yehuro hwemakore gumi nemasere kusvika pamakumi maviri nemashanu anoratidza kuti kusvuta mbesa kunoshandura hukuru, humiro uye huwandu hwemashoko maviri ehupi hunokosha.
Kusiyana kwouropi kusakanganiswa kwakaenzaniswa nevasina kusvuta kunobatanidzwa zvakananga nekuwanda kwembanje kunopedzwa, vatsvakurudzi vakawana.
Zvidzidzo zvekare zvevanhu vane tsvina yakaoma
Pakave nekudzidza kwakapfuura kwakabatanidza mbanje kushandiswa kuora mwoyo mukukurudzira, kutarisa, kudzidza, nekuyeuka. Zvidzidzo zvakaona kuti kushandiswa kwenguva refu kwemashonga kunogona kukanganisa kukurudzira . Zvimwe zvidzidzo zvakabatanidza mbanje kushandiswa pakudzidza kusakundikana uye unyanzvi hwemagariro evanhu .
Imwe tsvakurudzo yakawana kuti kusvuta mbanje kunogona kukanganisa kukwanisa kuchengetedza uye imwe yekudzidza yakawana kuti kushandiswa kwebambanje kutanga kunogona kukonzera kusagadzikana kwepfungwa kusingaonekwi kune avo vanotanga kusvuta mbanje gare gare muupenyu.
Kunyangwe Nguva Dzose Vakasvuta Vakabatwa
Asi vazhinji, kana kwete vose, vezvikoro izvi zvinosanganisira zvisingaperi, zvinorema mbanje dzinopfungaira. Kuongorora kwechangobva kuitwa, kwakabudiswa mu Journal of Neuroscience , ndiyo yekutanga kubatanidza zvisingabatsiri, dzimwe nguva mbanje inoshandisa zvisina kunaka pauropi.
Kunyange zvazvo kuenzaniswa kwekukura kwechidzidzo chacho chakanga chiri chiduku - makumi mana chete zvidzidzo zvese, kusanganisira 20 kwete-marijuana achishandisa masimba-kusiyana kwehupenzi hwemaviri aya kwaive kunoshamisa, vanyori vakarondedzera.
Vatsvakurudzi veNorweswestern University uye Massachusetts General Hospital / Harvard Medical School vakashandisa magnetic resonance imaging kuti ienzanise ubongo hwevechidiki vechidiki 20 vanozivisa kusvuta mbanje kamwe chete pavhiki nevamwe makumi maviri vane makore makumi maviri nemashanu kubva pamakore makumi mapfumbamwe nemakumi masere kusvika makumi mana nemakumi maviri nemakumi maviri nemasere avo vasina kuzivikanwa nezvakaitika kare.
Zvisingabatsiri, Kuvaraidza Vashandi chete
Masayendisiti akayera izwi, chimiro uye huwandu hwemukati wejeri muyucleus accumbens uye amygdala. Nucleus accumbens inobatanidzwa mumubairo kugadziriswa nekugadzirisa zvisarudzo, asi amygdala inosanganiswa nemanzwiro.
Vatori vechikamu vakaongorororwa kuti vaone kuti hakuna munhu ainge aine mbanje kana mamwe mimwe mishonga uye hapana mumwe wevatori vechikamu akambotambudza chero mimwe mishonga.
Vaya vakashandisa mbanje vakakumbirwa kuti vaenzanise mari yavo yekushandisa mbanje kwemwedzi mitatu, kusanganisira nhamba yemazuva vanoputa uye chiyero chemishonga inopedzwa zuva rega rega.
Kukura, Chimiro uye Kuwedzerwa Kwakachinja
Vatsvakurudzi vakawana kuti kana vanoshandisa marijuana vachidaro vanopedza kudya, izvo zvakanyanya kusakanganiswa kwemukati wekuunganidza accumbens uye amygdala pamifananidzo yeMRI. Chimiro nekuwedzerwa kwezvikamu zvose zveuropi zvakange zvakasiyanawo pakati pevashandi vebambanje nevasiri vashandisi.
Uhu hwevaya vaidya imwe chete yezuva rimwechete kana avo vaidya kamwechete pavhiki vakashandurwa.
"Chidzidzo ichi chinomutsa nharo yakasimba kune pfungwa yokuti mari inoshandiswa inoshandiswa isingabatanidzi nemigumisiro yakaipisisa," akadaro Hans Breiter, MD mumwe wevanyori vezvidzidzo. "Vamwe vevanhu ava vakashandisa mbanje chete kuti vadzoke kamwe kamwe kana kaviri pavhiki,"
Kushandiswa Kamwe Kamwe Kunogona Kukonzera Matambudziko
"Vanhu vanofunga kushandiswa kwekugadzirisa zvishoma hakufaniri kukonzera dambudziko, kana mumwe munhu ari kuita zvakanaka nebasa kana kuchikoro.Data yedu inotaura zvakananga izvi hazvisizvo," Breiter akati mune imwe nhau yakabudiswa.
Vamwe vatsvakurudzi, vasingabatanidzi muMassachusetts General kudzidza, vakabvuma kuti kuwana shanduko muhupenzi hwevashandisi vekusvuta marijuana zvaishamisa.
"Chidzidzo ichi chinoratidza kuti kunyange chiedza kusvika pakuenzanisa kushandiswa kwebhonji kushandiswa kunogona kukonzera kuchinja kwehutano hwehupfungwa," akadaro Carl Lupica, PhD, weNational Institute on Drug Abuse. "Izvi zvinyorwa zvinonakidza zvikuru nokuti zvidzidzo zvekare zvave zvakanyanya kunyanya kuurwere hwemagetsi anokonzera kusvuta, uye havana kunyanya kufunga nezvehutano hwevashandi vasingashamisi."
Tsvakurudzo yakabhadharwa neNational Institute on Drug Abuse, Office of National Drug Control Policy, Counterdrug Technology Assessment Center, uye National Institute of Neurological Disorders uye Stroke.
