Cov txiaj ntsig ntawm txoj kev tshawb pom tshiab qhia tias ntxiv rau lub hlwb, peb saj thiab hnov tsw kuj tseem cuam tshuam nrog sab nplaig.

Cov kws tshawb fawb tau ntev xaus tias tib neeg pom kev saj qab los ntawm lawv lub hlwb. Qhov tseeb, thaum peb nqos los yog pom ib qho khoom noj, peb tus nplaig thiab lub qhov ntswg paub txog nws qab thiab xa cov cim rau peb lub hlwb. Cov cim no tau ua tiav thiab cov ntaub ntawv tau muab rho tawm uas qhia peb tias peb noj dab tsi.

Tsis ntev los no, hauv txoj kev tshawb nrhiav tshiab hauv Philadelphia, cov kws tshawb fawb xaus lus tias nws ua tau rau cov khoom noj saj thiab hnov ntxhiab ua ntej los ntawm tus nplaig.

Lub tswv yim rau txoj kev kawm no yog los ntawm pab thawj coj pab pawg 12-xyoo tus tub, Dr. Mehmet Ozdener, kws paub keeb kwm ntawm lub xov tooj ntawm Monel Center for Chemical Research in the Senses nyob Philadelphia.

Tus me nyuam tub nug nws txiv, Dr. Ozdener, yog tias muaj nab npuaj lawv tus nplaig kom deb li deb vim tias lawv xav hnov ntxhiab ib puag ncig lawv.

Qhov tseeb, tus menyuam yeej yog lawm. Cov nab tau siv lawv tus nplaig los kuaj ntxhiab. Los ntawm nws, lawv ntes lawv cov lwg me me thiab xa tawm mus rau qhov thiaj li hu ua Jacobson plab hnyuv siab raum - lub cev tshwj xeeb uas muaj nyob hauv lawv qhov ncauj. Cov kab mob no muaj nyob hauv amphibians, tsiaj yug menyuam thiab qee cov tsiaj reptiles. Nws yog ib qho khoom siv ntxiv txuas nrog olfactory hloov khoom nruab nrog. Yakhauj lub cev tso cai rau nab rau lawv kuj tseem hnov ntxhiab tsw dhau tus nplaig tsis yog los ntawm koj lub qhov ntswg.

Raws li tib neeg, saj thiab ntxhiab tsw yog nyias muaj nyias cov kab ke, cov ntaub ntawv los ntawm kev sib koom ua ke thiab ua hauv lub hlwb.

"Kuv tsis tau hais tias yog tias koj qhib koj lub qhov ncauj, koj yuav hnov ntxhiab dab tsi. Peb txoj kev kawm yuav pab piav qhia qhov tsw tsw ntxhiab lwg me qauv hloov peb kev nkag siab saj. Qhov no tuaj yeem pab tsim cov ntxhiab tsw-tsw qab ua kom pab tua tau cov ntsev ntau dhau, qab zib thiab rog uas cuam tshuam nrog cov kab mob xws li kev rog dhau thiab ntshav qab zib, "hais tias Dr. Ozdener.

Rau lawv cov kev tshawb fawb, pab neeg tau siv tib neeg kev saj cov noob uas tau loj hlob hauv cov khoom neeg tsim sim kuaj. Zoo li cov khoom ntuj tsim, lawv muaj cov tshwj xeeb lwg me me uas nyob hauv olfactory cov hlwb hauv peb lub qhov ntswg thiab paub txog cov ntxhiab tsw.

Cov kws tshawb fawb tau siv cov txheej txheem tshawb fawb zoo ntawm "kev paub txog calcium", uas tau sim seb cov keeb kwm ncau rau cov hlwb hnov zoo li cas rau cov ntxhiab tsw txawv. Lawv pom tias thaum raug ntxhiab tsw, lawv tau tawm los ua olfactory.

Pab neeg no yog thawj ua qhia txog tib neeg li cas saj buds tuaj yeem pom cov ntxhiab tsw. Qhov no txhais tau hais tias nws muaj peev xwm ua rau olfactory thiab gustatory receptors nyob rau ntawm tus nplaig los koom tes hauv kev ntes tus ntxhiab.

Qhov xaus ntawm txoj kev tshawb no tau lees paub los ntawm kev sim txuas ntxiv ntawm cov kws tshawb fawb los ntawm Monel Center.

Tus sau hais tias txoj kev tshawb fawb no hais tias "muaj olfactory thiab gustatory receptors hauv tib lub xov tooj ntawm tes ua rau peb tshawb xyuas qhov sib txheeb ntawm qhov hnov tsw thiab saj hauv lub qhov ncauj,"

Cov kws tshawb nrhiav tau hais tias lawv tsuas yog nyob rau theem pib ntawm lawv txoj kev kawm. Lawv npaj ntsuam xyuas seb puas yog olfactory receptors muaj nyob hauv txhua lub cell saj lossis tsuas yog hauv qee qhov ntawm lawv thiab cov pa tsw tsw zoo muaj rau ntawm qhov saj uas pom los ntawm cov receptors saj.
