Cov thawj lub mloog pob ntseg cortex nyob hauv qhov zoo tshaj ntawm lub cev nqaij daim tawv ntawm lub lobe sab hauv thiab nthuav mus rau sab sulcus ib sab thiab lub cev nqaij daim tawv transverse (tseem hu ua Heschl's gyri). Kev ua suab zaum kawg yog ua los ntawm parietal thiab frontal lobes ntawm tib neeg lub paj hlwb cortex.

Ib yam li ntawd, nws tau nug, qhov twg yog thawj lub mloog pob ntseg cortex nyob qhov xeem?

Nws yog thaj tsam ntawm lub lobe ntawm sab cev nqaij daim tawv uas tau txais lub suab thiab yog lub luag haujlwm rau lub peev xwm hnov. Nws yog ib qho tseem ceeb ntawm lub paj hlwb cortex uas lees txais hnov cov ntaub ntawv los ntawm lub cev nruab nrab nruab nrab. Nws yog thawj cortical thaj tsam ntawm hnov txoj kev.

Ib yam nkaus, lub hemisphere twg yog lub mloog pob ntseg hauv? Nyob rau hauv qhov zoo tshaj ntawm qhov lub cev nqaij daim tawv ntawm txhua lub hemisphere, lub mloog pob ntseg cortex muaj ob qho tib si thawj (idiotypic) thiab theem nrab (tsis yog homotypic) cortices. Qhov qub yog nyob hauv lub sijhawm operculum (Brodmann cheeb tsam 41 thiab ib feem ntawm 42) thiab raug xa mus ua Heschl's gyrus.

Ib qho ntxiv, qhov twg yog qib ob lub pob ntseg mloog pob ntseg nyob?

Thawj lub mloog pob ntseg yog nyob raws ntawm lub qhov ncauj ntawm lub lobe sab hauv sab hauv sab nraub qaum. Secondary auditory cortex , uas tau txais kev kwv yees los ntawm thawj lub mloog pob ntseg , lus dag raws ntug zoo tshaj ntawm ib sab ntug ntawm lub lobe sab cev nqaij daim tawv yog li ib puag ncig thawj cortex.

Lub chaw hnov lus ntawm lub paj hlwb nyob qhov twg?

Thawj hnov cortex (A1) yog nyob ntawm qhov ua tau zoo tshaj plaws ntawm lub cev hauv lub lobe ntawm sab cev nqaij daim tawv thiab tau txais cov ntsiab lus taw tes-rau-taw qhia los ntawm kev faib tawm ntawm lub nruab nrab ntawm lub nruab nrab geniculate complex; yog li, nws muaj daim ntawv qhia tonotopic tseeb.
