Indlela ezibona ngayo

i-zebrafish ibona kanjani umhlaba?

Iziteshi ezine zamakhoni kanye nokubuka okuseduze kwepanoramic

I-zebrafish inezigaba ezine ze-cone—i-ultraviolet, eluhlaza okwesibhakabhaka, eluhlaza nokubomvu—kwi-retina eyakhelwe amanzi agqamile angashoni. Amehlo ayo aseceleni ahlola ama-degree angu-339 emzimbeni wonke, kuyilapho ukuhlolwa kokuziphatha kwabantu abadala kubeka ukuqonda kwendawo emijikelezweni engu-0.56 kuya ku-0.58 kuphela ngedigri ngayinye. Imininingwane emihle iyafiphala, kodwa umbala kanye nokumbozwa okuseduze kwepanoramic kuhlala kumaphakathi.

Ukubona kuka-i-zebrafish kucace kangakanani?

Amehlo ayo ahlukanisa cishe ama-cycles angu-0.57 ngedigri (No direct Snellen equivalent; 0.56–0.58 cpd behavioural OKR), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-339°.

i-zebrafish ubona kanjani umuntu?

Amehlo ayo ahlukanisa cishe imijikelezo engu-0.57 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-105 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.

Yimiphi imibala i-zebrafish engayibona?

Amakilasi ama-cone amane aphakela amasekhethi e-retina aphikisana nombala. Ezibungwini, ishaneli ye-ultraviolet endaweni engaphezulu yangaphambili ikhethekile ukuze ibone inyamazane ekhanyayo e-ultraviolet.

i-zebrafish ibona kanjani ebumnyameni?

I-retina iqukethe izinti nama-cones. Kumaseli abantu abadala angawodwa, izimpendulo zenduku zazicishe zibe izikhathi ezingama-40 kuya kwezingu-220 ezizwela kakhulu kunezimpendulo zekhoni; umbala ngokuyinhloko uwumsebenzi wokukhanya okukhanyayo.

Ukubona kuka-i-zebrafish kuqhathaniswa kanjani nokomuntu?

Abantu basebenzisa izigaba ezintathu zamakhoni futhi ababoni i-ultraviolet; I-zebrafish isebenzisa ezine futhi ikhava amadigri angu-339 kunokuba cishe u-200. Isikrini se-RGB singasebenzisa kuphela umbala ongamanga kanye nokufiphala okulinganiselwe ukuze kukhulunywe lowo mehluko, singalokothi sikhiqize kabusha ngokoqobo.

Yini eyisipesheli ngokubona kuka-i-zebrafish?

Amakilasi ama-cone amane, kufaka phakathi imisebe ye-ultraviolet
Ukumbozwa kwabantu abadala okungu-339-degree enomkhakha wezimpumputhe wangemuva ongu-21-degree
Fronto-dorsal acute zone; ama-larval ultraviolet cones asebenza ngokukhethekile ekubambeni inyamazane
