Qhov sib txawv tseem ceeb ntawm kev hnov lus thiab somatosensory yog qhov kev hnov lus hais txog thaj chaw somatosensory thawj zaug uas tau txais cov ntaub ntawv hnov qab thaum somatosensory hais txog thaj chaw somatosensory theem nrab uas yog lub luag haujlwm rau kev ua cov ntaub ntawv hnov qab.
Tib neeg lub hlwb tau txais cov cim ntawm lub paj hlwb thoob plaws hauv lub cev thiab ua cov cim qhia txhawm rau tsim cov kev tsim nyog los tawm tsam cov stimuli tau txais. Yog li ntawd, lub hlwb yog lub luag hauj lwm rau kev ua txhua yam stimuli paj hlwb generated. Sensory yog thawj cheeb tsam somatosensory tam sim no nyob rau hauv lub ridge ntawm lub cortex. Lub cheeb tsam somatosensory theem nrab nyob tom qab mus rau thawj cheeb tsam somatosensory. Ob qhov chaw hnov qab thiab thaj chaw somatosensory ua raws li txoj kev somatosensory uas suav nrog peb lub neurons: thawj, theem nrab, thiab qib siab.
Dab tsi yog Sensory?
Sensory yog thaj tsam ntawm tib neeg lub hlwb uas tau txais cov ntaub ntawv hnov lus xws li siab, kub, mob, thiab kov. Primary somatosensory cortex (S1) yog lwm lo lus uas piav txog kev hnov qab. Thaj chaw hnov tsw yog nyob rau hauv tib neeg lub hlwb, tom qab ntawm lub hauv paus sulcus (postcentral gyrus). Cov cheeb tsam no tau txais kev kwv yees los ntawm nuclei ntawm thalamus ntawm lub hlwb. Qhov no suav nrog tau txais kev sib txawv ntawm cov receptors nyob thoob plaws lub cev.

Cov kev xav no muaj xws li mob, kov, kub, siab, thiab proprioception. Lub cheeb tsam kev hnov lus yog suav nrog Brodmann thaj chaw 1, 2, 3a, thiab 3b. Tawm ntawm plaub qhov chaw, cheeb tsam 3 yog lub luag haujlwm rau qhov siab tshaj plaws ntawm somatosensory tawm tswv yim los ntawm thalamus. Lub cheeb tsam hnov tsw muaj peev xwm los nrhiav thaj chaw tiag tiag uas qhov kev xav tshwj xeeb tshwm sim. Qhov no tso cai rau tus neeg los txheeb xyuas qhov tseeb qhov chaw ntawm qhov kov, mob, siab, thiab lwm yam. Cov cheeb tsam hnov tsw kuj pab txiav txim siab kwv yees qhov hnyav ntawm ib qho khoom los ntawm kev saib nws.
Somatosensory yog dab tsi?
Somatosensory yog thaj tsam ntawm tib neeg lub hlwb uas pab kom tau txais thiab ua cov ntaub ntawv xav tau los tsim cov lus teb thiab kev nco. Kev txais cov cim muaj xws li kov, qhov mob, thiab qhov kub ntawm lub cev. Secondary somatosensory cortex (S2) yog lwm lo lus uas piav txog somatosensory. Nws yog tam sim no posterior thiab nyob ib sab mus rau thawj cheeb tsam somatosensory (sensory) nyob rau sab sauv ntawm sab laug sulcus ntawm lub cortex ntawm lub hlwb. Somatosensory txuas nrog rau thaj tsam hnov qab. Nws kuj tau txais kev kwv yees ncaj qha los ntawm thaj tsam thalamus ntawm lub hlwb. Lub cheeb tsam somatosensory muaj Brodmann thaj chaw 40 thiab 43.
Daim duab 02: Somatosensory Region
Somatosensory lossis theem nrab somatosensory yog koom nrog hauv kev paub txog cov khoom tactile thiab nco. Yeej, thaj av somatosensory pab khaws cia, txheej txheem, thiab khaws cov ntaub ntawv tau txais los ntawm cheeb tsam sensory. Lub cheeb tsam somatosensory muaj kev sib txuas nrog hippocampus thiab amygdala. Qhov no yog qhov laj thawj tseem ceeb uas tso cai rau kev txais cov ntaub ntawv los ntawm ib puag ncig thiab tsim kev txiav txim siab yuav ua li cas nrog qhov xwm txheej uas siv cov ntaub ntawv khaws cia los ntawm cov xwm txheej zoo sib xws yav dhau los thiab tus neeg xav li cas txog cov ntaub ntawv ntsig txog qhov xwm txheej.
Dab tsi yog qhov zoo sib xws ntawm Sensory thiab Somatosensory?
- Sensory thiab somatosensory muaj nyob rau hauv parietal lobe ntawm lub hlwb.
- Cov cheeb tsam no code somatosensory information.
- Ob qhov chaw hnov qab thiab thaj chaw somatosensory muaj cov neurons zoo sib xws.
- Cov lus teb neural no yog cov lus teb zoo sib xws.
- Ob cheeb tsam muaj Brodmann thaj chaw.
Qhov txawv ntawm Kev Ntsuas thiab Somatosensory yog dab tsi?
Lub cheeb tsam hnov los yog thawj thaj chaw somatosensory tau txais cov ntaub ntawv hnov los ntawm ntau qhov chaw ntawm lub cev thiab cov txheej txheem. Lub cheeb tsam somatosensory lossis theem nrab somatosensory yog lub luag haujlwm los tsim cov lus teb tactical rau cov ntaub ntawv xav tau txais thiab khaws cov lus teb hauv kev nco. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev xav thiab somatosensory. Sensory nyob rau hauv lub postcentral gyrus, thaum somatosensory nyob rau hauv lub Upper ib feem ntawm lub lateral sulcus. Ntxiv mus, Brodmann cov cheeb tsam 1, 2, 3a thiab 3b yog tam sim no nyob rau hauv lub sensory cheeb tsam thiab 40 thiab 43 yog tam sim no nyob rau hauv lub somatosensory cheeb tsam.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm kev hnov lus thiab somatosensory hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Sensory vs Somatosensory
Sensory thiab somatosensory yog ob thaj tsam ntawm somatosensory system. Sensory yog thawj cheeb tsam somatosensory, whilst somatosensory yog cheeb tsam somatosensory theem nrab. Thaj chaw hnov tsw tau txais cov ntaub ntawv hnov lus, thaum thaj tsam somatosensory tsim cov lus teb tactical rau cov ntaub ntawv xav paub raws li kev paub dhau los. Ob leeg muaj Brodmann cov cheeb tsam thiab zoo sib xws ntawm cov neurons. Yog li, qhov no qhia txog qhov sib txawv ntawm kev hnov lus thiab somatosensory.
