He aha te wiri 40 Hz? Ko te rangahau a te MIT e whakarerekē ana i te pūtaiao o te mate a Alzheimer

Ka taea e te wiri tinana katoa 40 Hz te whakahohe i te ara o te roro ki te whakakore i ngā pūmua e pā ana ki te mate Alzheimer's. Ehara tēnei i te whakapae noa iho — he hua tēnei o te tekau tau o ngā rangahau a MIT, i manatokohia motuhaketia e ngā taiwhanga puta noa i ngā whenua maha. Ki te hiahia koe ki te mārama ki te pūtaiao kei muri i te whakaora wiri, tīmata i konei.

He aha i tika ai kia aro nui ki tēnei rangahau

He ngāwari noa iho te whakakorekore i te wiri whakaora. He maha ngā tau e whakapau kaha ana te umanga oranga ki te tāpiri i ngā kereme hauora koretake ki ngā taputapu engari he iti noa iho te mahi. Nō reira, ki te tino pakari te pūtaiao, ka hunaia e te haruru.

He rerekē tēnei. I ahu mai te rangahau mō te whakaohooho 40 Hz i te Picower Institute for Learning and Memory o MIT — tētahi o ngā whare wānanga pūtaiao roro e tino whakahuatia ana i te ao. I tīmata me tētahi pepa i te tau 2016 i roto i te Nature , tētahi o ngā hautaka pūtaiao tino whiriwhiri. Mai i taua wā, kua tāruatia, kua whakawhānuihia hoki e ngā tīma motuhake i te Harvard Medical School, ngā whare wānanga i Kōtirana, me ngā whare wānanga rangahau i Haina.

I te marama o Poutū-te-rangi 2025, i whakaputa te taiwhanga o Tsai i tētahi arotake whānui i roto i te PLOS Biology e whakarāpopoto ana i ngā kitenga mō te tekau tau puta noa i ngā rangahau maha. Kāore i āta tirohia, i āraia rānei te whakatau: he pono, he tipu haere, he ōrite hoki te pūtake taunakitanga mō te whakaohooho gamma 40 Hz me te hauora o te roro puta noa i ngā taiwhanga.

Ehara tēnei i te rangahau kotahi e whai hua ana. He tekau tau tēnei o ngā taunakitanga whakakotahi mai i ngā umanga motuhake. He mea nui taua rerekētanga.

He aha te 40 Hz, ā, he aha ngā mea e tupu ana i roto i te roro?

Ka whakaputahia e tō roro ngā aukume hiko i ngā auau rerekē i runga i tāna mahi. I te wā moe hōhonu, ka puhoi ngā ngaru. I te wā e mataara ana, ka tere ake ngā ngaru. I te 40 huringa ia hekona — 40 Hz — ka whakaputahia e te roro ngā mea e kiia nei e ngā tohunga roro he ngaru gamma. E pā ana ēnei ki te aro nui, te mahara mahi, me te mahi tahi i waenga i ngā rohe roro rerekē e ahu mai ana i te whakaaro mārama.

I roto i te hunga e pāngia ana e te mate a Alzheimer, ka tino heke te mahi gamma. Ka ngaro te manawataki o te roro. Mō ngā tau, i whakaarohia tēnei he tohu o te neurodegeneration - he mea e puta ana i te whanaketanga o te mate. I pātai a MIT i tētahi atu pātai: me pēhea mēnā ko tētahi wāhanga hoki o te mea e akiaki ana i te mate ki mua? Ā, mēnā koinā, ka taea e te whakahokinga mai i taua manawataki te whakahohe i ngā parepare o te roro?

Āe te whakautu. He pūnaha whakakore para tō te roro — he momo whatunga rerenga wai ā-roto e tango ana i ngā pūmua paitini i ngā wā okiokinga me te whakaohooho. I kitea e ngā kairangahau o MIT, mā te whakaohooho 40 Hz ka whakahohe i tēnei pūnaha. Ka tahuri i te tukanga horoi o te roro, ka whakanui ake i te whakakorenga o ngā pūmua amyloid me te tau e kohia ana i roto i te mate a Alzheimer.

Te Tikanga o Tēnei — Mō Te Hunga Katoa e Whakaaro Ana Mō Te Hauora o Te Roro

Kāore te hiranga o tēnei rangahau i te herea noa ki te hunga whai mate a Alzheimer. Ko ngā tikanga i kitea e ia — te pūnaha whakakore para o te roro, te tiaki i ngā hononga io, te whakaiti i te hanga pūmua — he mea nui ki te hauora o te roro puta noa i te roanga o te oranga.

Mena kei te hiahia koe ki te tiaki i te mahi hinengaro i a koe e pakeke haere ana, koinei tētahi o ngā huarahi kore-rongoā kua tino tuhia paitia kei raro i te rangahau pūtaiao nui i tēnei wā. Kāore e whakamahia he rongoā, kāore e hiahiatia he tirotiro haumanu mō te whakamahinga hauora, ā, kei te mārama haere te tikanga.

Mena kei te tautoko koe i tētahi mema o te whānau kua kaumātuatia, kei te mahi rānei koe i tētahi wāhi e āwangawanga ana mō te hekenga o te hinengaro, ka tukuna e te rangahau tētahi mea tūturu: he auau motuhake, he tikanga motuhake, me tētahi huinga taunakitanga kei muri i tēnā - ehara i te kereme oranga koretake.

I whakaatuhia i roto i tētahi rangahau i te tau 2023 mō te neke atu i te 100 tāngata i Kōtirana he pai ake te maumahara mā te whakamahi i te whakaohooho auau-gamma. I whakaatuhia e tētahi tīma o Harvard te whakahekenga tau ine i roto i ngā tūao tangata. Ehara ēnei i te rangahau kararehe. Kei te haere tonu te whakamaoritanga ki te tangata, ā, he rite tonu ngā hua wawe ki ngā mea i matapaetia e ngā tauira kararehe.

Kāore e taea e ngā taputapu wiri katoa te mahi i tēnei

Koinei te wā e whai pānga tika ai te pūtaiao ki ngā mahi tūturu.

I whakamahia e te rangahau ngā taputapu e taea ai te tuku i tētahi tohu 40 Hz pumau, tika hoki. Ehara i te mea tūpono noa iho taua motuhaketanga — ko te kaupapa matua tēnei. Ka uru te roro ki te manawataki e whiwhihia ana e ia. Mēnā he hē te auau, he koretake, he hē noa rānei, kāore te pānga e puta.

Ko te nuinga o ngā papaaho wiri a ngā kaihoko e whakamahi ana i ngā motuka hiko hei whakaputa wiri. Ko te auau e whakaputaina ana e rātou ka whakatauhia e te hanganga ā-tinana o te motuka — kāore e taea te whakahaere tika, ā, kāore e taea te raka pono ki te 40 Hz. Ko te mea ka rongohia e koe i runga i te pereti wiri paerewa he nekehanga ā-ringa, ehara i te auau kua whakaritea.

He rerekē te mahi a te hangarau wiri oro. Ka whakamahia e ia ngā whakawhiti oro - he rite tonu te kaupapa ki te kaikorero - hei huri i te tohu hiko hei wiri ā-ringa. Nā te mea ko te auau e tautuhia ana e te tohu hiko, ka taea te whakarite me te pupuri me te tika. Ko te 40 Hz he 40 Hz, he pumau, he pumau hoki puta noa i te wā.

I hangaia ngā taputapu a Didahealthy i runga i tēnei mātāpono, i hangaia hei tuku i ngā auau e tika ana mō te haumanu — tae atu ki te 40 Hz — me te tino tika e hiahiatia ana e te rangahau. Tirohia ngā whakaritenga katoa mō te taputapu i konei.

Ngā mea kāore anō kia whakapumautia e te rangahau

Ko te pono ki ngā herenga he wāhanga o te whakaaro nui ki te pūtaiao.

Ko ngā taunakitanga tino kaha mō te whakaohooho 40 Hz me te mate a Alzheimer i ahu mai tonu i ngā tauira kararehe. Kei te haere tonu ngā whakamātautau tangata, ā, he pai ngā hua wawe, engari kāore anō kia oti ngā whakamātautau whakahaere matapōkere nui i roto i te tangata. Kei te whakatauhia tonutia te tikanga tino pai - te roa, te auau, te kaha.

Ko tā te rangahau e whakaatu mārama ana ko te ahunga: ka uru te whakaoho gamma 40 Hz ki ngā tikanga koiora tūturu, he rite tonu ngā taunakitanga puta noa i ngā taiwhanga motuhake, ā, kei te anga whakamua te mara ki te whakamahinga tangata me te maia haere. He pakari te pūtaiao. Kei te haere tonu te arotautanga.
