Maminitsi makumi matatu anodzivirira huropi hwako kwehupenyu hwese

Chidzidzo ichi chakaitwa nevaongorori vepaAmerican University yeMaryland, uye mhedzisiro yavo yakaburitswa mune yazvino chinyorwa cheScientific Journal yeInternational Neuropsychological Society.

Kuti vasvike pane zvakawanikwa muchidzidzo, vaongorori vakayera chiitiko chehuropi vachishandisa fMRI yevatori vechikamu vane hutano vane makore makumi mashanu neshanu kusvika makumi masere nemashanu.

Chikwata chakakumbirawo vatori vechikamu kuti vaite mabasa endangariro aisanganisira kuziva mazita ane mukurumbira uye asingafarirwe.

Sekureva kwechidzidzo ichi, maitiro ekurangarira mazita ane mukurumbira anomutsa neural network ine hukama nesemantic ndangariro, iyo inozivikanwa kuderera nekufamba kwenguva nekuda kwekuderera kwendangariro muvakuru.

Miedzo iyi yakaitwa maminetsi makumi matatu mushure mekuita kurovedza muviri kwakanyanya pabhasikoro rekurovedza muviri, uyezve vakamhanya bvunzo dzakafanana asi pazuva rekuzorora apo vatori vechikamu vasina kuita maekisesaizi.

Vatsvagiri vakawana kuti maekisesaizi aita kuti huropi hushande munzvimbo dze4 cortical dzinoita ndangariro, iyo yainyanyozivikanwa yaive "hippocampus" - inoshanda kubatanidza uye kutora ruzivo pazvinenge zvichidikanwa - zvichienzaniswa nekuzorora.

Vatsvakurudzi vakaratidza kuti hippocampus inoderera nezera uye nzvimbo yehuropi inoratidzirwa kune mapuroteni anokuvadza anotungamirira kuchirwere cheAlzheimer.

"Ongororo dzakapfuura dzakaratidza kuti kurovedza muviri nguva dzose kunogona kuwedzera huwandu hwehippocampus, asi kudzidza kwedu kunopa ruzivo rutsva rwekuti kurovedza muviri kwakanyanya kunokwanisa kukanganisa iyi yakakosha nzvimbo yehuropi," akadaro muongorori anotungamirira Carson Smith.

"Sezvinongoita mamhasuru anoenderana nekudzokorora maekisesaizi, maekisesaizi ega ega anogona kuwedzera neurocognitive network nenzira dzinowedzera kuchinjika kwavo kukwegura, kuwedzera kutendeseka kwetiweki uye kushanda, uye kubvumira kuwana kunobudirira kundangariro."

Chirwere cheAlzheimer ndicho chinonyanyo zivikanwa sechirwere chedementia, uye chinotungamira mukuramba kuchidzikira mukugona kufunga nekushanda kwehuropi, uye kurasikirwa nendangariro. Chirwere ichi chinofambira mberi zvishoma nezvishoma kusvika pakurasikirwa kwekukwanisa kuita mabasa ezuva nezuva, uye kutaurirana nemhoteredzo, uye mamiriro acho anogona kuipa kusvika pakushayikwa kwekushanda kwekushanda.
