dc.description.abstractA four-parameter model of spectral sensitivity curves was developed. Empirical equations were designed for A(1)- and A(2)-based visual pigments with the main a-band maximum absorptions (lambda(max)) from 350 nm, near the ultraviolet, up to 635 nm in the far-red part of the spectrum. Subtraction of the alpha-band from the full absorbance spectrum left a "beta-band" described by a lambda(max)-dependent Gaussian equation. Compatibility of our templates with A(1)- and A(2)-based spectra was tested on the electroretinographic (ERG-derived) scotopic action spectra recorded in dogfish shark, eel, Prussian carp and perch. To more precisely estimate the accuracy of our model, we compared it with widely used templates for visual pigments. There was almost no difference between the tested models in fitting the above-mentioned spectral data. One of the advantages of our model is that in the fitting of spectral sensitivity data it uses non-transformed wavelengths and the shape of the curve remains the same for a broad range of lambda(max) values. Compared to multiparameter templates of other authors, our model was designed with fewer (four) parameters, which we believe can bring us closer to understanding the true nature of the absorption curve.en
