Color vision mak tak tak i nei bawk em? He theihna tlemte (Tetrachromacy) hi i zir dawn teh ang!

Mi thenkhatin keini aia rawng an hmu tam thei em tih i ngaihtuah ngai em? Vawiin hian chutiang thiltihtheihna danglam tak, mak deuh, mahse mak tak mai chu kan sawi dawn a ni. Hei hi medical science-a `(Tetrachromacy)` an tih chu a ni. A awlsam zawngin, thil thleng chu mi ṭhenkhat, a bik takin hmeichhiate chuan mi dangte aiin rawng maktaduai tam tak chu fiah lo zawkin an thliar hrang thei a, an hre thei bawk. Mak a ni lo maw? Hetiang thil hi engtin nge a lo awm tih i lo en ang u.

Tetrachromacy chu eng nge ni?

A awlsam zawngin `(Tetrachromacy)` hi theihna tlem tak a ni. Hetiang theihna nei te hian an mit ah hian cell chi li an nei a, chu chuan rawng a hmu thei a ni. Mi tam zawk chuan heng cell chi thum hi kan nei a. Heng cell te hi `(cones)` kan ti thin. Kan mit hnung lama `(retina)` ah an awm a. Heng cone te hi light detect tu leh thluak ah rawng chungchang information thawn thintu an ni.

Tunah chuan han ngaihtuah teh, cone chi thum nei mi pakhat chuan rawng maktaduai engemaw zat a thliar hrang thei a, a hre thei bawk. Tin, he cone chi palina neitu hi engtin nge ni ang? Anni hian rawng maktaduai za tam tak an thliar hrang thei a, an hre thei bawk ! Chu chu kan hmuh aiin khawvel rawng hrang hrang leh nung zawk an hmu mai thei tihna a ni.

Mahse buaina tlemte a awm. Mithiamte chuan he natna, ``Tetrachromacy'' tia koh hi a awm leh awm loh hriat theihna tur test rintlak an la hmu lo. Chuvangin engtiang chiahin nge a awm fo emaw, a tlem em tih emaw chiang taka sawi a harsa hle. Internet-a i zawn chuan "Tetrachromacy Test" tih ang chi hi i hmu mai thei. Mahse, dik tak chuan online-ah he thil hi dik taka hriat theihna tur a awm lo . Chuvângin, chu fiahnate chu rin lutuk loh chu a ṭha ber.

Engtin nge tetrachromacy hian hna a thawh?

``Tetrachromacy'' nei te hian cone chi khat extra an nei tih kan sawi tawh a. He extra cone hian rawng tam zawk an hmu thei a ni. Kan mitmenga awm tlangpui cone chi thum hi han thlir ila:

• Red (L cone): Red hian wavelength sei tak a nei a. Chuvang chuan L cone an ti a ni.
• Green (M cone): Hei hi hmuh theih spectrum lai takah a awm a, wavelength chu medium a ni. Chuvang chuan M cone an ti a ni.
• Blue (S cones): Blue hian wavelength tawi a nei a. Chuvangin hengte hi S cone an ni.

``Tetrachromacy`` nei te hian he cone type palina hi an nei fo thin a, chu chu orange hnaih ber rawng ah a sensitive ber a ni. He cone type palina hi genetic mutation avanga lo awm a ni. Chu chu genes inthlak danglamna a ni.

Chuti a nih chuan, engtin nge he cone palina hian color vision hi a fiah lo em em?

Hetiang hian han ngaihtuah teh. He cone chi palina hi cone dangte’n color information an khawlkhawm nen a inang a, mahse a inang chiah lo.Thu hriat belh a ni. Tichuan i thluak chuan heng rawng hrang hrang information zawng zawng hi a process vek a, chu chuan i rawng sensitivity chu a tipung lehzual a ni. Chuvangin ``Tetrachromacy'' nei te hian a let za tam takin rawng an hmu tam zawk a ni.

Engvangin nge mi thenkhat chuan he cone palina hi an siam chhuah?

Hei hi a chhan chu kan genes-ah a awm a ni. A bik takin, L cone control tu gene, red detect tu chu X chromosome -ah a awm a ni.

Tunah en teh, mipa i nih chuan X chromosome pakhat i nei a ni. Chuvangin, chutah chuan mutation a awm a nih chuan i L cone zawng zawng chu a danglam vek ang a, color blindness chi khat i nei thei bawk.

Mahse, hmeichhiate hian X chromosome copy pahnih an nei thung. Chuvangin, copy pakhatin mutated gene a neih chuan normal L cone a nei thei a, chutiang bawkin mutated L cone pawh a nei thei bawk. Hmeichhia 12% velin he natna hi an nei a ni. Mahse, an vai hian `(Tetrachromacy)` dik tak an nei vek lo. Chutiang a nih theih nan chuan thil pahnih dang tihhlawhtlin a ngai a ni:

1. Cone palina hian frequency sensitivity danglam tak a nei tur a ni. Chu chu cone dangte aiin rawng hrang hrangah a sensitive tur a ni tihna a ni. Chutiang a nih loh chuan thluak hian extra cone atanga information a dawn hmang hian color sensitivity a tipung thei dawn lo.

2. I thluak hian color information process nan color channel pali a neih a ngai a. A tlangpuiin mihring thluak hian colour channel pathum chauh a nei a. Cone chi li nei mah la, color channel pathum chauh i neih chuan chu extra color information chu i hmang tangkai thei dawn lo.

Cone chi li leh color channel pathum i nei ang tih han ngaihtuah teh. Chutih lai pawh chuan tetrachromacy "chak lo" tak i nei thei a ni. Chutiang mite chuan mi pangngai aiin color vision test-ah an ti tha zawk tlangpui. Mahse, heng tetrachromacy level chak lo/chak tak takte hi a awm tak tak em tih leh an hnathawh dan hriat chian nan zirchianna neih belh a ngai a ni.

Pawimawh: Hei hian `(Tetrachromacy)` hi extra cone neih mai ni lovin, thluak insiam dan pawh a ni tih a tilang.

Engtin nge tetrachromacy dik tak chu test a nih?

Tetrachromacy i neih leh neih loh hriat nan zirchiangtute hmanraw lian ber pakhat chu DNA testing hi a ni . Kan mit chhunga cone awmte hnathawh dan tur chu eng gene nge thunun tih zirchiangtute chuan an hre chiang hle. Chuvangin mutations awm theihna hmun leh a thlen theihna tur mutations bik thenkhat chu an hre chiang hle.

Mahse, DNA test ringawt pawh hian Tetrachromacy i nei tih a finfiah thei lo. Hardware specialized tak, man to tak a mamawh a ni. Tin, test te hi lighting condition in result a nghawng lohna hmunah tih a ngai bawk. Hengte hi research center leh university nena inzawm hospital-ah te tih a ni tlangpui.

Online test i nei thei lo em ni?

No. `(Tetrachromacy)` hriat theihna tur online test dik tak a awm lo .. Hei hi computer leh technological device tam tak hmanga tih theih a ni lo. A awlsam zawngin, device tam zawk screen-ah hian taksa lamah chuan ``Tetrachromacy'' nei te chauh hmuh theih tur khawpa rawng a lang thei lo .

Kan hmanraw hman zawng zawng (desktop, laptop, tablet, smartphone) ang bawkin screen hian color channel pathum a nei a, chungte chu: red, green, leh blue (kan mit a cone awm ang bawkin). Heng channel te hi a tam ber a, a chhan chu mi tam zawk mit hian chutiang chuan hna a thawk tha ber a ni. Mahse, tunlai screen-ah hian colour channel palina a lantir thiam lo a, chuvangin tetrachromacy a lantir thiam lo.

Online color sensitivity test pawh hi rintlak a ni lo. A chhan chu an dik theih nan chuan i hman tur monitor/screen hi a calibrate tha hle tur a ni. I awmna room rawng pawh hian a nghawng thei bawk.

Tetrachromacy nei te hian engtin nge an hmuh?

Tetrachromacy "chak lo" nei te hian mi pangngai aiin colour vision an nei tha zawk. Mahse, Tetrachromacy "chak" ("Tetrachromacy" tia koh dik tak) nei te hian rawng sensitivity level mak tak an nei a ni . A tlem berah chuan mi pangngai aia a let sang tam takin rawng an hmu tam zawk.

Hei hi tlem tal hriatthiam theih nan dichromacy (cone chi hnih chauh) nei te hi han ngaihtuah teh. Cone chi hnih chauh nei mahse, rawng chi hrang hrang 10,000 vel an hmu thei. Keini ang mi, trichromats (cone chi thum nei) te hian rawng maktaduai khat atanga maktaduai sawm vel an hmu thei a ni. Chu chu dichromat aiin a let 100 atanga 1000 velin a tam zawk a ni. Tichuan, tetrachromacy nei mi pakhatin rawng a hmuh theih dan tur chu han ngaihtuah teh!

Thil pawimawh dang chu rawng i hmuh dan hi ``subjective`` a ni . Chu chu, i tana danglam bik, mimal thila rawng i hmu tihna a ni. Research atanga a lan dan chuan hei hi color vision danglamna nei lote zingah pawh a dik a ni. Chu chu thil pakhat rawng chungchangah miten an inrem lohna chhan pakhat a ni (Internet-a ``viral`` post-a hmuh tur a awm fo angin).

Chuti a nih chuan, engtin nge tetrachromacy i nei tih i hriat theih ang?

Vanduaithlak takin he zawhna hi chhanna awlsam a awm lo. Online test hian eng ang pawhin tiam mah se, he zawhna hi chhan theih a ni lo. Pakhatnaah chuan hmeichhia chauhin `(Tetrachromacy)` an nei thei niin a lang . Tin, `(Tetrachromacy)` dik tak hi a tlem em em a, hri kai hmuhchhuah hi an tlem hle bawk.

Tetrachromacy i nei mai thei nia i ngaih chuan a finfiah theihna awmchhun chu scientific researcher-te nena special test neih hi a ni. Tetrachromacy chak tak i nei tih i hriat chuan i chhehvel boruak i en thei a, mi tam zawkin an tawn ngai loh leh an hriatthiam ngai loh angin rawng tin, rawng tin, rawng tinreng i tawng thei ang.
