Mukufuna kupanga zisankho zanzeru? Kenako idyani nthawi zonse, kupewa kuchuluka kwa shuga m'magazi! Chitsimikizo cha lamulo losavutali chinachokera ku Sweden: kutengera zotsatira za kafukufuku wawo waposachedwapa, asayansi ochokera ku Salgrenska Academy ku yunivesite ya Gothenburg amalangiza kuti musapange zisankho pamimba yopanda kanthu, chifukwa mukakhala ndi njala, hormone ghrelin imapangidwa. , zomwe zimapangitsa kuti zosankha zanu zikhale zopupuluma. Pakadali pano, kutengeka ndichizindikiro chofunikira cha matenda ambiri a neuropsychiatric ndi zovuta zamakhalidwe, kuphatikiza kadyedwe. Zotsatira za kafukufuku zomwe zasindikizidwa mu magazini Neuropsychopharmacology, kumene portal "Neurotechnology.rf" imatanthawuza.
Zomwe zimatchedwa "hormone yanjala" ghrelin imayamba kupangidwa m'mimba pamene shuga wamagazi amatsika kwambiri (ndipo kusintha kotereku kwa shuga kumalimbikitsidwa, makamaka, ndi kugwiritsa ntchito molakwika shuga ndi zakudya zina zoyeretsedwa komanso kunyalanyaza thanzi. zokhwasula-khwasula). Asayansi a ku Sweden poyesera makoswe (werengani zambiri pansipa) kwa nthawi yoyamba adatha kusonyeza kuti ghrelin yambiri m'magazi, kusankha kwanu kumakhala kosavuta. Kusankha mopupuluma ndiko kulephera kukana kukhutiritsa chikhumbo chakanthaŵi, ngakhale chitakhala chosapindulitsa kapena chovulaza. Munthu amene amasankha kukhutiritsa zilakolako zake mwamsanga, ngakhale kuti kudikira kudzawathandiza kwambiri, amadziŵika kuti ndi wopupuluma, kutanthauza kulephera kupanga zosankha mwanzeru.
"Zotsatira zathu zidawonetsa kuti ngakhale kuchepa kwazing'ono kwa ghrelin kudera la ventral tegmental - gawo la ubongo lomwe ndi gawo lalikulu la dongosolo la mphotho - linali lokwanira kupanga makoswe kukhala opumira. Chinthu chachikulu ndi chakuti pamene tinasiya jekeseni hormone, "kulingalira" kwa zisankho kunabwerera ku makoswe, "akutero Karolina Skibiska, mlembi wamkulu wa ntchitoyi.
Impulsivity ndi chizindikiro chazovuta zambiri zama neuropsychiatric ndi machitidwe, monga chidwi cha deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), autism spectrum disorders, kuledzera kwa mankhwala osokoneza bongo komanso vuto la kudya. Kafukufukuyu adawonetsa kuti kukwera kwa milingo ya ghrelin kudapangitsa kusintha kwanthawi yayitali mu majini omwe amasokoneza "joy hormone" dopamine ndi ma enzymes ogwirizana nawo, omwe ali ndi mawonekedwe a ADHD ndi OCD.

Kodi ndendende asayansi a ku Salgrenska Academy adazindikira bwanji kuti kuchuluka kwa ghrelin kumachotsa makoswe pa cholinga chawo choyambirira chopeza phindu komanso mphotho zambiri? Asayansi amasonkhezera makoswe ndi shuga akamachita zinthu moyenera. Mwachitsanzo, adakankhira chowongolera pamene chizindikiro cha "forward" chikumveka, kapena sanachisindikize ngati chizindikiro cha "stop" chikuwonekera. M’kusankha kwawo, iwo “anathandizidwa” ndi zizindikiro za kuthwanima kwa kuwala kapena phokoso linalake, zimene zinamveketsa bwino zimene ayenera kuchita panthaŵiyo kuti alandire mphotho yawo.
Kukanikiza cholozera pamene chizindikiro choletsedwa chinali kuwonedwa ngati chizindikiro cha kutengeka. Ofufuzawo adapeza kuti makoswe omwe amapatsidwa Mlingo wa intracerebral wa ghrelin, omwe amatsanzira chilakolako cham'mimba cha chakudya, amatha kukanikiza chowongoleracho osadikirira chizindikiro chololeza, ngakhale izi zidawapangitsa kutaya mphotho.
