| Abstract |
|
Spectral sensitivity of the dark-adapted frog's eye, eye cup and isolated retina was studied by means of an electroretinogram between 280 and 580 nm. Spectral sensitivity curve of isolated retina shows three peaks corresponding to α-, β- and protein absorption bands of the rhodopsin. Quantum yield of retinal excitation in the protein band, at 280 nm, is 0.45. Ocular media ofRana temporaria are transparent down to 330 nm so that the whole eye shows an appreciable sensitivity in the near ultraviolet. This fact may be of some ecological importance.
