Ntchito ya Alpha ndi chitsanzo cha zochita za ubongo zomwe zimasonyeza kukhala maso ndi maso otsekedwa ndipo nthawi zambiri zimayambitsa kugona. Zimapezeka ndi chiyero cha masentimita asanu ndi atatu kapena 13 pamphindi (Hz) ndipo zimayesedwa bwino m'dera la occipital la ubongo, lomwe liri kumbuyo kwa mutu.
Zomwe mawonekedwe a Alfa amachita zimatanthauza kuti ubongo uli momasuka, koma ukadali maso.
Mafunde a Alfa alipo pomwe mukukambirana kapena mukuganiza mozama kapena kusinkhasinkha, ndipo akhoza kupangidwanso panthawi yochita masewera olimbitsa thupi. Kuwonjezereka kwa ntchito ya alfabeta kunapezedwanso kuti kulimbikitsa kulenga, ndipo kungachepetsere zizindikiro za kuvutika ndi kupweteka kosalekeza poonjezera luso lanu losanyalanyaza zowawa, kafukufuku amapeza.
Ukagona, ubongo nthawi zambiri sumabala mafunde a alpha. Koma nthawi zina, zochitika zosayenera za alfabata zingachititse kuvutika kwa kugona. Apa ndi momwe machitidwe a alpha akuyendera, ndi zomwe muyenera kudziwa momwe maubongo amakhudzira kugona kwanu.
Kodi Olemba Ntchito Akuyesedwa Bwanji?
Chiyeso chodziwika kwambiri pa mawonekedwe a ubongo, kuphatikizapo mafunde a alpha ndi ntchito ya alpha, ndi electroencephalogram ( EEG ). Kwa mayeso, ma electrodes ang'onoang'ono a zitsulo omwe amatha kuyeza ubongo amaikidwa pamphuno. Zotsatirazo zimawerengedwa ndi katswiri wa zamaganizo, omwe angagwiritse ntchito chidziwitso kuti adziwe zovuta zosiyanasiyana, kuphatikizapo matenda okhudza kugona komanso chiopsezo cha kugwidwa.
Pamene Ntchito ya Alpha ikudodometsedwa
Zosokonezeka zamtundu wa alpha zingapangitse kusakhoza kupumula ndi khalidwe labwino la kugona. Chitsanzo chimodzi cha izi ndi alpha-EEG yosavomerezeka , kachitidwe kakang'ono kogona komwe kamapezeka makamaka mwa anthu omwe ali ndi fibromyalgia. Pamene agona tulo tofa nato, ubongo uyenera kubala mafunde a delta.
Kwa anthu omwe ali ndi matenda a alpha-EEG, ubongo umapanga mafunde a alpha nthawi yomwe zimangotulutsa mafunde a delta, zomwe zingachititse kuti asakhale ndi nkhawa komanso asagone.
Mitundu Yina ya Mafunde Aubongo
Mafunde a Alpha ndi amodzi mwa maubongo ambiri omwe amagwira ntchito momwe timaganizira, kumverera, kulankhulana, kugona komanso kugwira ntchito.
Delta Waves: Pa .5 mpaka 3 Hz, mafunde a m'mphepete mwa nyanja ndi mafunde ochepa kwambiri omwe amabwera ubongo ndipo amawoneka akugona.
Theta Waves: Pakati pa 3 mpaka 8 Hz, mafundewa amabwera nthawi yogona, ndipo amawonedwa m'maganizo akuluakulu a kusinkhasinkha.
Mafunde a Beta: Awa ndi mafunde ambiri a ubongo wamasiku, omwe ali ndi chiwerengero cha 12 mpaka 30 Hz. Iwo ali otchuka mu mayiko odzuka bwino komanso pamene mukuika maganizo pa zokhudzana ndi chidziwitso ndi ntchito zina, monga kuthetsa mavuto kapena kusankha zochita.
Mafilimu a Gamma: Awa ndiwo mafunde amphamvu kwambiri, omwe ali ndi chiwerengero cha 25 mpaka 100 Hz. Amakonza zambiri kuchokera kumadera osiyanasiyana a ubongo ndipo ali ndi udindo wozindikira.
