Gut Brain Evidence

Meicníocht

Cad é an gnáthóg ghoile-bréine i ndáiríre?

Cór comhoibrithe fíor, atá curtha in iúl go forleathan i n-ainmhithe, agus atá i bhfad níos lú bunaithe i na daoine a dhíoltar é.

Na cosáin

Conas a dhéanann an gut comhoibriú leis an inchinn
CosánMeicníochtFianaise i ndaoine
Nervus vagusIonsruth na snáitheanna a iompar comharthaí an ghoile chuig an mbrainstamBunaithe go hanatamaíoch; tá sé deacair ról cúiseach a thástáil
Táirgí miocróbachTá aigéid shóideacháin ghearra agus réamhábhair neurotransmitter ag dul isteach sa chiorcalInmhéadraithe; éifeachtaí síos an sruth neamhchinnte
Comharthaíocht imdhíonachtaInmhéadaitheacht an ghoile agus cytokines inflamatóireBunaithe na comhoibrithe; tá an treo conspóideach
Aicsean HPAAthraíonn hormóin struis feidhmiú an ghoile agus vice versaDúbailte agus go maith doiciméadaithe
Cór néarógach entericNeuróin ghoile intíre ag feidhmiú go leath-neamhspleáchGo maith curtha in iúl

Níl aon rud anseo i gcéin. Tá céadta milliún neurón i gcór néarógach enteric agus feidhmíonn sé le neamhspleáchas suntasach. Tacaíonn staid an ghoile le giúmar agus tacaíonn giúmar le feidhmiú an ghoile, mar a fhios ag duine ar bith a bhí neirbhíseach roimh scrúdú.

Cosáin comhoibrithe gut-brain

An fadhb treo

Taispeánann athbhreithniú córais difríochtaí microbiota idir daoine le dúlagar nó imní agus rialuithe [2]. Is é an cheist a chinneann gach rud cén treo a thagann an saighead.

Athraíonn dúlagar an méid a itheann daoine, cé mhéad a ghluaiseann siad, conas a chodlaíonn siad agus go minic cén cógas a thógann siad. Athraíonn gach laige sin an microbiome. Mar sin, tá difríocht i gcomhdhéanamh miocróbach go díreach mar a bheadh ​​ag súil le dúlagar a chúisíonn athrú ar an microbiome agus nach ndéanann an microbiome aon rud ar chor ar bith.

Tá an deacracht chéanna i bhfeidhmiú an chonradh meitibileach [3] agus i ngníomhaíocht an autistice [4], áit a bhfuil rogha aiste bia coitianta agus a thabharfadh difríochtaí microbiome ar a shon féin.

Cad a shocróidh é

Trialacha randamacha maidir le hidirghníomhachtaí microbiome sainithe le críochfoirt cliniciúla, tréimhse chuí agus méid sampla cuí. Tá na cinn sin ag tosú le feiceáil agus is é an chúis a athróidh an leathanach seo. Go dtí sin, is é an suíomh macánta ná go bhfuil an t-aicsean ann agus nach bhfuil na hiarratais tomhaltóra bunaithe air cruthaithe — féach probiotics.

Ceisteanna coitianta

An bhfuil an putóg i ndáiríre ina "dara hinchinn"?
Tá an córas néarógach einteiriceach mór agus leathneamhspleách, mar sin tá bunús leis an meafar. Ní smaoiníonn sé, agus tá an frása ag déanamh níos mó oibre margaíochta ná oibre tuairisciúla.
An dtagann 90% den seratóinin ón bputóg?
Déantar an chuid is mó de sheratóinin an choirp sa phutóg, agus ní thrasnaíonn sé an bacainn fola-inchinne. Is dobhareanna atá ar leithligh den chuid is mó iad seratóinin an phutóig agus seratóinin na hinchinne, rud a fhágann an t-éileamh ar lár de ghnáth.
An féidir le hathrú m'aiste bia m'aoibh a athrú trí mo phutóg?
Bíonn tionchar ag aiste bia ar aoibh trí go leor bealaí. Níor éiríodh leis an micribhiaim a leithlisiú mar an idirghabhálaí i ndaoine fós.
Cad ba cheart dom a dhéanamh i ndáiríre?
Ith níos mó snáithín agus bia coipthe. Is í seo an idirghabháil a bhfuil an fhianaise is fearr agus an costas is ísle aici — féach snáithín.
