Qee cov zaub mov tsis qab los noj mov los ntawm kev cuam tshuam rau lub hlwb los ntawm kev saj buds.

Kev noj qab haus huv yog tswj los ntawm thaj tsam ntawm lub hlwb hu ua hypothalamus. Tom qab noj mov, lub cev nce cov tshuaj hormones insulin thiab leptin. Lawv ua rau lub hypothalamus, thiab nws blocks qab los noj mov.

Txawm li cas los xij, nws muaj peev xwm tswj tau qab los noj mov yam tsis muaj cov tshuaj hormones - los ntawm kev saj buds. Qhov no yog ua tau ua tsaug rau lub hlwb hlwb, tanycytes, uas kab lub fundus ntawm lub thib peb ventricle nyob rau hauv lub hlwb. Tanycytes tau txais cov ntaub ntawv hais txog zaub mov los ntawm lawv cov saj ntawm tus nplaig thiab xa cov cim qhia rau hypothalamus raws lawv cov ceg ntev.

Nws tau xav tias lawv tsuas teb rau cov qab qab zib xwb. Tab sis tsis ntev los no, cov kws tshawb fawb tau pom tias tanycytes kuj tau qhib los ntawm saj ntawm umami. Qhov no yog "thib tsib saj" uas tshwm sim los ntawm muaj cov amino acids nyob rau hauv cov zaub mov.

Hauv kev tshawb fawb los ntawm University of Warwick, cov kws tshawb fawb tau ntxiv cov amino acids tseem ceeb rau lub hlwb tseem ceeb. Qhov muaj zog thiab ceev tshaj cov tshuaj tiv thaiv ntawm tanycytes yog muab los ntawm ob yam tseem ceeb amino acids: lysine thiab arginine. Tsuas yog 30 vib nas this, tanycytes pom cov amino acids thiab xa cov ntaub ntawv mus rau hypothalamus.

Thaum koj noj cov zaub mov uas nplua nuj nyob rau hauv arginine thiab lysine, umami saj receptors ntawm lub saj buds ntawm tus nplaig ntes lawv muaj thiab xa cov lus mus rau lub hlwb. Nyob ntawd, tanycytes teb rau lawv, xa cov cim rau hypothalamus, thiab qab los noj mov.

Cov qib amino acid hauv cov ntshav thiab hauv lub hlwb tom qab noj mov yog qhov tseem ceeb heev uas qhia tau tias muaj kev puv puv. Qhov tseeb tias tanycytes ncaj qha paub cov amino acids yuav pab tsim txoj hauv kev tshiab los tiv thaiv kev rog.
