Ko te roro te okana tino whakamiharo, tino uaua hoki o tō tātou tinana. He rite ki te rorohiko nui. Ko ngā mea katoa e whakaarohia ana, e pā ana ki a tātou, e maumahara ana, e akohia ana e tātou, e whakahaerehia ana e tēnei okana iti nei. Nō reira, i tēnei rā ka kōrero tātou mō te wāhanga tino nui o tēnei rorohiko nui, arā, ko te "kiri" kei waho tonu o te roro. I roto i te rongoā, ka kiia tēnei ko te cerebral cortex , ko te `(Cerebral Cortex)` rānei.
He aha te Cerebral Cortex?
Ki te kī ngāwari, ko te roro matua te paparanga angiangi rawa o waho e karapoti ana i te wāhanga nui o tō tātou roro e kiia nei ko te roro matua. Mēnā kua kite koe i tētahi pikitia o te roro, he āhua kōpikopiko, he piko hoki, tika? Nā tēnei roro matua taua āhua kōpikopiko.
Whakaarohia, ki te hiahia koe ki te tākai i tētahi pepa nui ki roto i tētahi pouaka iti, me whakapiko, me kuru, tika? Waihoki, he mea hanga ō tātou roro ki ngā kita hei whakauru i te maha o ngā neuron. Mā ēnei kita ka nui ake te horahanga o te mata o te cortex roro. Tata ki te 2,500 henimita tapawha te rahi! Mā tēnei ka taea e ō tātou roro te tukatuka i ngā mōhiohio me te whakaaro i ngā mea uaua ake.
Ahakoa he torutoru mirimita noa te matotoru o tēnei paparanga, e 50% pea te matotoru o te katoa o te roro. E kiia ana kei roto i tēnei paparanga te 14 ki te 16 piriona pūtau io .
Ko ngā awaawa hohonu e puta mai ana i tēnei āhua miro ka kiia ko ngā "sulci" ā, ko ngā kopa kua ara ake ka kiia ko ngā "gyri". Koinei ngā hanganga e pupuri ana i ngā miriona pūtau io e tika ana mō te mahi a tō tātou roro.
He aha i huaina ai tēnei ko 'Gray Matter'?
Kua rongo pea koe i te kupu 'hina hina'. Koinei te tikanga o tēnei wāhanga o te roro. Kāore he hipoki ngako o ngā pūtau io i tēnei wāhanga e kiia nei ko te `(myelin)`. Koia te take he hina. Ko ngā muka io i roto i te 'matū mā' i roto i te roro kua kapihia ki te `(myelin)`, nō reira he mā.
Ngā wāhanga matua o te roro me ā rātou mahi
Ko te nuinga o te wā, e wehea ana te roro kia rua ngā taha maui me te taha matau. Ko te taha maui me te taha matau ēnei taha e rua. E honoa ana ēnei taha e rua mā te piriti i hangaia mai i te tini o ngā muka io e kiia nei ko te "corpus callosum". Mā tēnei ka whakawhitiwhiti kōrero i waenga i ngā taha e rua.
Hei tāpiritanga, kua wehea anō ia o ēnei tuakoi ki ngā rohe matua e whā, arā, ngā lobes. He mahi motuhake tā ia o ēnei lobes. Me titiro tātou ki ērā.
| Pūwero | Ngā mahi matua | Ngā tohu o te kino |
|---|---|---|
| Te Pūwero o Mua Te wāhanga o mua rawa o te roro, i muri i te rae |
|
|
| Te Pūpū Parietal Kei te tihi o te māhunga, i waenganui i ngā wheua o mua me ngā wheua parietal |
|
|
| Te Pūwero o te Wā Kei runga ake i ngā taringa, i ia taha o te roro |
|
|
| Te Pūwero o te Tuakiri Te tuara o te upoko, i runga ake i te kaki |

He aha te mea ka tupu mēnā ka pakaru te cortex roro?
He maha ngā take matua e pakaru ai tēnei wāhanga nui o te roro. Hei tauira:
- Ngā pukupuku roro
- Whiu
- Te toto ki roto i te roro
- Ngā mate pūnaha ārai mate
- Ngā whara nui o te upoko
E ai ki te ripanga i runga ake nei, he rerekē rawa ngā tohu i runga i te wāhanga o te roro kua pakaru. Hei tauira, ka rerekē pea te āhua o te tangata mēnā ka pakaru te pito o mua o te roro. Waihoki, ka ngaro pea te tirohanga mēnā ka pakaru te pito o muri o te roro.
He mea tino nui: Ki te pāngia koe, tētahi atu rānei e mōhio ana koe e tētahi o ēnei tohu, kaua e whakaaro noa , engari me toro atu ki tētahi tākuta whai tohu tonu. He tino tairongo ngā take e pā ana ki te roro, nō reira he mea nui kia rapu tohutohu hauora wawe tonu.
Ko te roro te pokapū whakahaere o tō tātou tinana. Koinei te mea e "tātou" ai tātou. Nō reira, ko te mōhio ki ēnei kōrero mō te roro matua, te wāhanga tino nui o taua rorohiko nui, ka tino āwhina i a tātou kia mōhio ki tō tātou hauora.
Karere Tangohia ki te Kāinga
- Ko te roro matua te wāhanga o waho rawa, te wāhanga miro, te wāhanga whakaaro o tō tātou roro. E kiia ana hoki ko te "mea hina".
- Mā ōna kita me ōna kōpuku ka taea te pupuri i te maha atu o ngā pūtau io i roto i te wāhi iti ake.
- E whā ngā wāhanga matua (te taha mua, te taha parietal, te taha temporal, me te taha occipital), ā, he mahi motuhake tā ia wāhanga (pēnei i te kōrero, te tirohanga, te mahara, me te whakatau kaupapa).
- He rerekē ngā tohu o te pakaru ki te cortex roro i runga i te wāhi e puta ai te pakaru.
- Mena kei a koe ētahi tohu e pā ana ki te roro, he mea tino nui kia kaua e tātaritanga whaiaro, me te toro atu ki tō tākuta i te wā e taea ai.
