Kan taksa peng mak leh buaithlak ber chu thluak hi a ni. Supercomputer ang mai a ni. Kan ngaihtuah, kan hriat, kan hriat reng leh kan zir zawng zawng hi he taksa peng te tak te hian a thunun vek a ni. Chuvangin vawiin hian he supercomputer-a thil pawimawh ber, thluak pawn lama awm "bark" chungchang kan sawi dawn a ni. Damdawi lamah chuan hei hi cerebral cortex , emaw `(Cerebral Cortex)` kan ti a.
Cerebral Cortex hi eng nge ni?
A awlsam zawngin sawi ila, cerebral cortex hi kan thluak hmun zau tak, cerebrum an tih vel, pawn lam ber, te tak te, layer te tak te a ni. Thluak thlalak i hmuh tawh chuan a hrual leh a inzawm khawm angin a lang, a dik em? Chu wrinkled appearance chu he cerebral cortex vang a ni.
Ngaihtuah teh, lehkhabu lian tak chu bawm te tak teah i dah duh chuan i fold a, i chil a ngai a ni lawm ni? Chutiang bawkin kan thluak hi hetiang hian neuron tam thei ang ber awm theihna turin wrinkles atanga siam a ni. Heng wrinkles te hian cerebral cortex surface area nasa takin a tipung a ni. A dik tak chuan square centimetre 2,500 vel a ni! Hei hian kan thluak hian information tam zawk a process thei a, thil buaithlak zawk a ngaihtuah thei bawk.
He layer hi millimeter tlemte chauh ni mahse, kan thluak mass zawng zawng atanga 50% vel a ni. Nerve cell tluklehdingawn 14 leh 16 vel a awm nia chhut a ni .
Hetianga a hring hring (wrinkled nature) avanga groove thuk lo lo awmte hi ``sulci`` an ti a, a fold sang zawkte chu ``gyri`` an ti bawk. Hengte hi kan thluak hnathawhna atana pawimawh nerve cell maktaduai tam tak awmna structure te an ni.
Engvangin nge hei hi ‘Gray Matter’ an tih?
'Gray matter' tih thumal hi i hre tawh ngei ang. Chu chu he cerebral cortex hmun hi a ni. He part-a nerve cell-te hian `(myelin)` tih hming pu fatty covering an nei lo. Chuvang chuan a gray a ni. Thluak chhunga 'white matter' awm nerve fiber te hi `(myelin)` in a khuh a, chuvangin a var a ni.
Cerebral cortex peng lian ber ber leh an hnathawh dan
Kan cerebral cortex hi hemisphere inang pahnih ah then a ni ber. Chu chu veilam hemisphere leh dinglam hemisphere a ni . Heng hemisphere pahnih hi nerve fiber tam tak atanga siam bridge hmanga inzawmkhawm an ni a, chu chu ``corpus callosum`` an ti a ni. Hei hmang hian hemisphere pahnih inkarah hian information inthleng a ni.
Chu bâkah, heng hemisphere tinte hi bial lian pali, a nih loh leh lobe-ah an inṭhen belh leh a ni. Heng lobe tin hian hna bik an nei vek a. Eng nge an nih i han thlir teh ang.

Cerebral cortex a chhiat chuan eng nge thleng ang?
He thluak hmun pawimawh tak hi a chhiat theih chhan lian tak tak engemaw zat a awm. Entir nan:
- Thluak natna (brain tumor) a awm
- Thai
- Thluak chhunga thisen chhuak
- Autoimmune natna te
- Lu hliam na tak tak a awm
A chunga table-a kan hmuh ang hian thluak hmun chhia a zirin a natna lan chhuah dan a inang lo hle. Entirnan, mi pakhat chu a hmalam (frontal lobe) a chhiat chuan a mizia a danglam thei a ni. Chutiang bawkin occipital lobe a chhiat chuan mi mit a bo thei a ni.
Pawimawh tak: Nangmah emaw i hriat emaw hian heng symptoms te hi i neih chuan engmah ngaihtuah suh la , doctor emaw doctor emaw thiam tak hmu nghal rawh. Thluak kaihhnawih thil hi a sensitive hle a, chuvangin doctor thurawn rang taka lak a pawimawh hle.
Thluak hi kan taksa thununna hmun a ni. "Keini" min siamtu chu a ni. Chuvangin, chu supercomputer-a thil pawimawh ber, cerebral cortex chungchanga heng thudikte hi hriat hian kan hriselna hriatna kawngah min pui nasa hle ang.
Take-Home Thuchah a ni
- Cerebral cortex hi kan thluak pawn lam ber, hrual, ngaihtuahna nei ber a ni. "Gray matter" an ti bawk.
- A wrinkles leh folds te hian hmun tlem zawkah nerve cell tam zawk a nei thei a ni.
- Section lian pali (frontal, parietal, temporal, leh occipital)-ah ṭhen a ni a, chungte chuan hna bik (thusawi, mit hmuh, hriatrengna, leh thutlukna siam ang chi) an nei vek a ni.
- Cerebral cortex chhiatna chhinchhiahna hi chhiatna thlenna hmun azirin a inang lo.
- Thluak kaihhnawih symptom i neih chuan mahni inhriatchhuah loh a, a rang thei ang bera doctor pan a pawimawh hle.
