Alpha mafilimu a ubongo: kufotokoza, maonekedwe ndi ntchito

Ubongo ndi njira yovuta komanso yankho lokhazikika. Chifukwa cha zochitika zakunja, iye akhoza kusintha chiyero cha ntchito yake. Makhalidwe ake amapatsidwa mphamvu zowonongeka, malinga ndi momwe ntchito yamagetsi imagwirira ntchito.

Masiku ano, zilembo zinayi zazikulu za ubongo zimasiyana, kuphatikizapo alpha rhythm. Talingalirani chomwe chiri ndi chifukwa chake n'kofunika kwambiri kuti mukhale mu nyimboyi.

Mfundo zazikulu za ubongo

Masiku ano, mitundu ikuluikulu ya mawonekedwe a magetsi a ubongo wa munthu amasiyana. Iwo ali ndi maulendo awo omwe amadziwika ndi maulendo awo.

1. Chizindikiro cha alpha chikuwonekera panthawi yopumula mukumuka.
2. Beta-rhythm - mwachizolowezi akadzuka.
3. Mtundu wa Delta umapezeka mu tulo tofa nato.
4. Mtambo wa Theta ndi chikhalidwe cha kugona kosaya kapena kusinkhasinkha kwakukulu.

Alpha nyimbo ya ubongo: kupezeka

Mafunde a Alpha anapezeka zaka makumi angapo zapitazo ndi Hans Berger, yemwe anali ndi matenda a maganizo a ku Germany, pamene adazindikira kusuntha komwe maulendo angapo anali a dongosolo la 10 pamphindi. Matalikidwe awo ndi ofooka kwambiri, kupitirira 30 millionths of volt.

N'zochititsa chidwi kuti chiwerengero cha alpha chikuwonetsedwa mwa anthu okha. N'zosadabwitsa kuti patadutsa zaka zoposa makumi anayi, gawo lonse la sayansi linawonekera, lotchedwa electron-cephalography, kapena EEG.

Maphunziro a al-rhythm ndi ziwonetsero za Earth-ionosphere

Mu 1968, D. Cohen mwa njira yosayanjanako anawulula maginito osokoneza mutu pamutu omwe anawoneka pamodzi ndi magetsi okhudza ubongo. Mwafupipafupi, iwo amagwirizana ndi omwe amadziwika kuti "alpha zizindikiro za ubongo." Anatchula kuti magnetoencephalogram.

Wasayansi wina, Gray Walter, kumbuyo kwake, kumbuyo kwa 1953, adalongosola kuti ubongo umatha kuzindikira zotsatira za magetsi kumapatsa mwayi wogwirizana ndi mphamvu yowonjezereka ya zinthu zonse. Zimadziwika kuti mawonekedwe a magetsi otchedwa electromagnetic, omwe amafanana ndi maulendo a alpha-rhyth, ali pafupi ndi kutalika kwa dziko lapansi ndi chiwonetsero cha "Earth-ionosphere".

Zomwe zikuchitika, zimakhala zomveka bwino ataphunzira ntchito za Schumann, yemwe mu 1952 analosera, ndipo zitachitika izi zinatsimikizira kuti pali ziwonetsero za dziko lapansi-ionosphere. Maulendowa ankatchedwa mafunde akuyima m'mphepete mwawonekedwe "Earth-ionosphere". Kutalika kwa mawonekedwe a electromagnetic a main resonance ali pafupi ndi kutalika kwa chiwerengero cha Dziko lapansi. Schumann, pamodzi ndi Kening, adanena kuti tsiku lomwe amatchedwa "sitima", omwe matalikidwe ake amafikira 100 μV / m, ndi mafupipafupi a 9 Hz, amakhala makamaka kuyambira pa magawo atatu mpaka khumi, koma nthawi zina masekondi makumi atatu, anayamba kugwira ntchito. Mizere yochuluka kwambiri inalipo kuyambira 7 mpaka 11 Hz. Kawirikawiri mkati mwa tsiku mafupipafupi amafalikira amapezeka m'mabuku ochokera ku +/- 0,1 - 0,2 Hz.

Masana, mphamvu zowonongeka za dziko lapansi-ionosphere zalembedwa. M'masiku otetezeka pafupipafupi 8 Hz, kuchuluka kwa masewerawa ndi 0.1mV / m Hz, ndipo panthawi yamkuntho maginito kuwerenga kumawonjezeka ndi 15%.

Akatswiri ambiri amavomereza kuti chisangalalo cha magetsi opangira magetsi chimakhudzana ndi kutuluka kwa magetsi. Tikukamba za mphezi, zomwe zimawoneka pamwamba pa dziko lonse lapansi.

Chofunikira cha alpha nyimbo

Mu ubongo waumunthu, mawonetseredwe a ubongo, komanso zilembo za alpha, zikuwonetseratu zovuta zokhudzana ndi maganizo a psychophysiological. Deta yofufuza ndi chiwerengero imasonyeza kuti chiwerengero cha alpha chikhoza kukhala chibadwidwe komanso ngakhale cholowa.

Asayansi Warren McCulloch ndi Gray Walter adaganiza kuti ndi alpha-rhythm, mawonekedwe a mkati mwa zithunzizo amachitika pamene akuyang'ana pa vuto lina. Zochitika zochititsa chidwi zinapezeka pakati pa nthawi ya maonekedwe a maonekedwe ndi maulendo a mafunde a alpha.

Biorhythms pa nthawi yogona ndi kudzuka

Munthu akatseka maso ake, zizindikiro zake za ubongo zimakhala zolimba. Ndipo pamene maso akutseguka, ambiri a anthu mafunde awa amatha. Malingana ndi izi, Gray Walter adanena kuti chiwerengero cha alpha ndicho kufufuza njira zothetsera mavuto omwe amapezeka atapezeka.

Mafunde a Alfa amayamba kutsogoleredwa ndi ata nyimbo pooneka ngati akugona. Ndipo munthu amene akugona mwakachetechete, mafunde ambiri amatha kuwonjezeranso panthawi yogona ndi zizindikiro zina, mwachitsanzo sigma rhythm.

Gray Walter akukhulupirira kuti kugona ndilo gawo la nthawi zakale za munthu pamene anafunikira kuchoka ku ntchito yogwira ntchito. Mafunde a Delta mumalo amenewa, amateteza ubongo.

Maganizo osaganizira ndi othamanga

Mafilimu a ubongo a ubongo ndi munthu aliyense payekha. Kafukufuku wasonyeza kuti mu chiwerengero chachikulu cha anthu omwe adawafotokozera, kuthekera kwa kulingalira kosadziwika kunkachitika.

Zina mwazinthuzi, ngakhale kuti sizinali nthawi zambiri, anthu adakumana ndi omwe analibe alpha nyimbo ngakhale atatseka maso awo. Kwa anthu oterowo anali oyenera kulingalira mothandizidwa ndi zithunzi, koma zinali zovuta kwa iwo kuthetsa mafunso osadziwika.

Chizindikiro cha alpha-rhythm, malinga ndi sayansi, chimakhudza liwiro la mayankho ndi maganizo. Ndili msanga mofulumira, liwiro limene lingaliro ndi ntchito zikupangidwira.

Kuchokera pa zomwe zanenedwa zimakhala zomveka bwino kuti chilembo cha alpha chimagwirizanitsidwa ndi malingaliro omwe amapezeka mu ubongo. Kukhoza kwa malingaliro, kutsogolo ndi kuwerengera kunali kobadwa mwa munthu ngakhale m'mayambiriro oyambirira a mbiriyakale. Koma njira zogwiritsira ntchito ndi kuganiza zosawerengeka zinapezedwa kanthawi pang'ono. Timatcha makhalidwe ngati chifuniro cha munthu.

Kusiyana pakati pa munthu ndi zolengedwa zina zonse

Alpha nyimbo ndizofunikira kwa anthu. Ichi ndi chimene chimasiyanitsa ife ndi zinyama. Mu ubongo wa zinyama zokhazokha ndi zosavomerezeka pazinthu zina zoterezi zinalembedwa.

Anali Kening ndi othandizira ake omwe poyamba adapeza kugwirizana pakati pa chiwerengero cha alpha ya ubongo wa umunthu ndi chiwerengero chachikulu cha dziko lapansi mu 1960. Chifukwa cha maphunziro a misala kwa nthawi yaitali zakhala zikupezeka kuti pamene mphamvu ya kumunda yowonjezereka, zotsatira zake zachepetsedwa ndi pafupifupi 20 msec. Pakadakhala osasintha kuchokera pa 2 mpaka 6 Hz, nthawi inkawonjezeka ndi 15 ms.

Chofunika kwambiri cha alpha nyimbo

Alpha nyimbo mu ana amapangidwa ndi zaka 2-4. Kwa munthu wamkulu, amamuwona atatseka maso ake ndipo saganizira chilichonse. Panthawiyi, zozizwitsa zake zowonongeka zimachepa, ndipo mafunde omwe amasintha kuchokera ku 8 mpaka 13 Hz akuwonjezeka.

Malingana ndi kafukufukuyu, kuti mudziwe zambiri, nkofunika kuti mukhale ndi ubongo mu chiganizo chanu. Pamene mukusangalala, popanda kuganizira chilichonse, chikhalidwe cha mtendere chimabwera, chomwe chimatchedwa "chikhalidwe cha alpha". M'machitidwe a kumbuyo masewera a martial, amatchedwanso dziko la mbuye. Ndi panthawi zovuta kuti kuyankha kwa minofu kukuwonjezeke ndi chinthu cha khumi kapena kuposerapo, kusiyana ndi machitidwe a beta.

Mafilimu a Alpha ndi beta amachititsa kuti munthu wathanzi azikhala mwamtendere. Ndipo choyamba choyamba, chocheperako chimakhala chosautsa, makamaka munthu amatha kuphunzira ndi kupuma mokwanira. Nthawi zina, thupi limapanga enkephalins ndi beta-endorphins. Awa ndiwo mtundu wa "mankhwala", omwe ndi zinthu zomwe zimayambitsa mpumulo ndi chimwemwe.

Oledzera ndi osokoneza bongo sangathe kulowa mu chilembo cha alpha popanda zopatsa zina. Koma mukumwa kwauchidakwa, mphamvu ya alpha mkati mwake imakula kwambiri. Izi zikufotokozera chizoloŵezi chawo.
