# Te Tūranga o ngā Pūtau Niho i roto i te Whakawhitiwhiti Kōrero a ngā Pūtau Niho
He tukanga tino uaua te whakawhitiwhiti kōrero i roto i te pūnaha io, he mea nui mō te whakarite i ngā mahi maha e tika ana mō te ora. Kei roto i tōna pūtake ko ngā neurotransmitters – arā, ngā karere matū e whakahaere ana i te tuku tohu i waenga i ngā pūtau io, ngā neurons rānei. Ka rukuhia e tēnei tuhinga te tūranga nui o ngā neurotransmitters i roto i te whakawhitiwhiti kōrero i roto i ngā pūtau io, me te tūhura i ā rātou tikanga, ngā momo, me ō rātou pānga whānui ki ngā tukanga ā-tinana me te hinengaro.
## Ngā Tikanga o te Mahi a te Neurotransmitter
I roto i te ao o te pūtaiao roro, he mea nui ngā neurotransmitters mō te horapa o ngā nekehanga io puta noa i ngā synapses – arā, ngā āputa iti i waenga i ngā neurons. Ka tīmata te tukanga whakawhitiwhiti kōrero me te nekehanga hiko, e mōhiotia ana ko te pūmanawa mahi, e haere ana i te axon o te neuron presynaptic ki te pito axon. Kia tae atu ki te pito synaptic, ka whakaohohia e te pūmanawa mahi te tukunga o ngā neurotransmitters kua rongoatia i roto i ngā vesicles.
Ka haere ēnei neurotransmitters puta noa i te āputa synaptic ka herea ki ngā kaiwhakawhiwhi motuhake i runga i te neuron postsynaptic. Ka taea e tēnei herenga te whakaoho, te aukati rānei i te neuron postsynaptic, i runga i te āhua o te neurotransmitter me te momo kaiwhakawhiwhi e whai wāhi ana. Ka akiakihia e ngā neurotransmitters whakaoho, pērā i te glutamate, te depolarization o te membrane postsynaptic, ka whakanui ake i te tūponotanga o te pūmanawa mahi. I tetahi atu taha, ka puta te hyperpolarization i ngā neurotransmitters aukati pērā i te gamma-aminobutyric acid (GABA), ka whakaitihia te tūponotanga o te pūmanawa mahi.
He tino whakahaere te tukanga o te mahi a ngā neurotransmitter, kia tika ai te tuku tohu. Whai muri i te tukunga o ngā neurotransmitter me te herea o ngā kaiwhiwhi, ka whakarite ngā tikanga maha kia tangohia mai i te kapiti synaptic. Ko te tango anō, te whakahekenga whākōkī, me te horapa ngā tukanga matua e whakamutu ana i te mahi a ngā neurotransmitter, e pupuri ana i te homeostasis synaptic me te aukati i te whakaohooho tonu, te aukati rānei i te neuron postsynaptic.
## Ngā Momo o ngā Neurotransmitters
Ka whakarōpūtia ngā neurotransmitter ki ētahi wāhanga whānui i runga i tō rātou hanganga matū. Ko ētahi o ngā neurotransmitter e tino rangahauhia ana, e tino māramahia ana hoki:
### Ngā Waikawa Amino
Ko ngā waikawa amino ētahi o ngā neurotransmitters tino taketake i roto i te roro. Ko te Glutamate, he neurotransmitter whakaoho, e whai wāhi ana ki ngā mahi hinengaro pēnei i te ako me te mahara. Ko tōna hoa mahi, ko te GABA, te neurotransmitter aukati matua i roto i te roro, he mea nui hei pupuri i te taurite i waenga i te whakaoho me te aukati, kia kore ai e nui rawa te mahi a ngā neurons.
### Ngā Monoamine
Ko ngā monoamine, tae atu ki te dopamine, te norepinephrine, me te serotonin, i ahu mai i ngā waikawa amino, ā, he mahi nui tā rātou ki te whakahaere i te wairua, te whakaohooho, me ngā mahi hinengaro. He mea nui te dopamine ki te pūnaha utu o te roro me te whakahaere nekehanga. Ka mahi te norepinephrine i roto i te urupare whawhai-rere rānei, e whakarerekē ana i te aro me te urupare ki te ahotea. Ka pā te serotonin ki te wairua, te hiahia kai, me te moe, me ngā ngoikoretanga e hono pinepine ana ki ngā mate wairua pēnei i te pouri.
### Ngā Peptide
Ko ngā neuropeptides he mekameka poto o ngā waikawa amino e mahi ana hei neurotransmitters, hei neuromodulators rānei. Ko ētahi tauira ko te matū P, e whai wāhi ana ki te kite i te mamae, me ngā endorphins, e hono ana ki te whakamamae i te mamae me te ahuareka. He rerekē ki ngā neurotransmitters tawhito, he maha ngā pānga roa o ngā neuropeptides ki ō rātou neurons ūnga.
### Acetylcholine
He neurotransmitter ahurei te Acetylcholine, ā, he mahi āna i roto i ngā pūnaha io taha me ngā pūnaha io matua. I roto i te pūnaha io taha, he mea nui mō te whakahohenga o ngā uaua. I roto i te pūnaha io matua, he mahi nui tāna mō te aro, te whakaoho, me te mahara. Ko te koretake o te whakahaere o te acetylcholine he tohu o te mate a Alzheimer.
### Ngā Pūrini
Ko te ATP me tana hua pakaru adenosine he neurotransmitters purinergic. Ka mahi te ATP ki ngā kaiwhakawhiwhi purinergic, ā, he pānga whakaohooho i roto i ētahi ara neuronal. Ko te adenosine, i tetahi atu taha, he mahi aukati, ā, e whai wāhi ana ki te whakatairanga i te moe me te whakawhānui i te toto.
## Te Pānga Whānui o ngā Neurotransmitters
He mea nui te mahi tika o ngā pūnaha neurotransmitter hei pupuri i te homeostasis ā-tinana me te hinengaro. Ko ngā whakararuraru i roto i ngā tohu neurotransmitter e whai pānga ana ki te maha o ngā mate pūnaha io me te hinengaro.
### Ngā Mate Pūnaha
He hononga tata ngā mate pēnei i te mate a Parkinson me te mate haurangi ki ngā koretake o ngā neurotransmitters. Ko te nuinga o te mate a Parkinson nā te pirau o ngā neurons e whakaputa ana i te dopamine i roto i te substantia nigra, ka puta ai te ngoikore o te nekehanga. He maha ngā wā ka pā te mate haurangi ki te koretake i waenga i ngā neurotransmitters whakaoho me ngā neurotransmitters aukati, ka hua ake he pupuhi neurons rerekē me ngā hopuhopu.
### Ngā Mate Hinengaro
E whakaatu hohonu ana ngā mate hinengaro i te hiranga o te taurite o ngā neurotransmitters. He hononga nui te pouri ki te korenga o ngā monoamines pērā i te serotonin me te norepinephrine. Ko te schizophrenia, he mate uaua e tohuhia ana e te psychosis, e hono ana ki te koretake o ngā ara dopamine. Ko te mahi tahi uaua o ngā momo neurotransmitters e whakanui ana i te uaua o ēnei āhuatanga.
### Ngā Mahi Hinengaro
Ko ngā neurotransmitters anō hoki te pūtake o ngā tukanga hinengaro. Hei tauira, he mea nui te acetylcholine mō te ako me te mahara, ā, ka kitea ngā ngoikoretanga nui i roto i ngā āhuatanga pēnei i te mate a Alzheimer. He mea nui te Dopamine mō te ako me te hihiri e ahu mai ana i te utu, e awe ana i ngā whanonga mai i te whakatutukitanga mātauranga ki te waranga.
### Te ahotea me te manukanuka
Ko te urupare a te tinana ki te ahotea me ngā tikanga o te manukanuka he maha ngā neurotransmitters e uru ana. He mea nui te norepinephrine me te cortisol i roto i te urupare ahotea ohorere, e whakarite ana i te tinana mō te mahi tonu. Heoi, ka taea e te ahotea mau tonu te arahi ki te koretake o te whakahaere o ēnei pūnaha, ka whai wāhi ki te manukanuka me ētahi atu mate e pā ana ki te ahotea.
## Ngā Aronga ā-Mārama me ngā Pānga ki te Hauora
Mā te mārama ki ngā mahi tika a ngā momo neurotransmitters ka huaki ngā huarahi mō ngā wawaotanga rongoā. Ko ngā maimoatanga o nāianei mō ngā mate e pā ana ki te neurotransmitter ko ngā rongoā pēnei i ngā selective serotonin reuptake inhibitors (SSRIs) mō te pouri me ngā benzodiazepines mō ngā mate manukanuka. Heoi, kāore ēnei maimoatanga e whai hua whānui, ā, he maha ngā pānga taha ka puta mai.
Ko ngā rangahau hou e aro ana ki ngā huarahi whai kiko ake, pērā i ngā tikanga whakarerekētanga roro me te rongoā ira, e whai ana kia whakahokia mai te mahi noa o ngā neurotransmitter me te tino tika. Hei tāpiri, ko ngā whanaketanga o te neuroimaging me te koiora ngota ka oati ki te wetewete i ngā uauatanga o ngā pūnaha neurotransmitter, ka whakarei ake i tō tātou māramatanga me te maimoatanga o ngā mate pūnaha io me ngā mate hinengaro.
## Whakamutunga
Ko ngā neurotransmitters ngā pou here o te whakawhitiwhiti kōrero pūtau io, e whakahaere ana i te whānuitanga o ngā tukanga ā-tinana me te hinengaro. Ko ā rātou tikanga uaua me ngā momo rerekē e whakaatu ana i te matatau o te pūnaha io. I a ngā rangahau e haere tonu ana ki te whakatairanga i tō tātou māramatanga ki te mahi me te whakahaere a ngā neurotransmitter, kei a ia te kaha ki te huri i ngā maimoatanga mō te maha o ngā mate neurological me te hinengaro tino uaua. Ko te mārama ki te tūranga o ngā neurotransmitters ehara i te mea ka whakarei ake i tō tātou māramatanga ki te roro engari ka whakatuwhera hoki i te ara mō ngā rautaki rongoā whakarei ake, ka poipoi i te hauora hinengaro me te hauora io pai ake mō te miriona.
