Negative phototaxis not only facilitates predation evasion: avoidance of the blue-violet spectral range could also promote the larvae to withdraw towards the river midline in the case...

Moreover, we predicted the visual pigment absorption spectra based on electrophysiologically determined spectral sensitivity in two...

...Amy Streets; Hayley England; Justin Marshall ABSTRACT Stomatopod crustaceans, or mantis shrimps, are known for their extensive range of spectral sensitivity but relatively poor spectral discrimination. Instead of the colour-opponent mechanism of other colour vision systems, the 12 narrow-band...

We examine their spectral sensitivity along with their dynamic range and temporal resolution. Our results show that they possess one class of photoreceptors with a single visual...

All photoreceptors have some sensitivity to UV light, which is noticeably decreased in B. bufo and virtually disappears in R. temporaria...

Depending on the experimental conditions, spikes varied from small to action potential-like events, with their amplitudes and rates decreasing...

Spectral sensitivity, which affects both achromatic and chromatic (colour) vision, also varies across the retina, though the function of this inhomogeneity is less clear.

... of the locust. In addition to previously characterized opsins of long-wavelength-absorbing (Lo1) and blue-absorbing visual pigments (Lo2), we identified an opsin of an ultraviolet-absorbing visual pigment (LoUV). DRA photoreceptors exclusively expressed Lo2, had peak spectral sensitivities at 441 nm and showed...

... sensitivities of the photoreceptors are rather simple, and peak in the ultraviolet, blue and green wavelength regions. The ommatidia have neither perirhabdomal nor fluorescent pigments, which modulate photoreceptor spectral sensitivities in a number of other butterfly species. These features are primitive...

Intracellular recordings demonstrated that the spectral sensitivities of the proximal photoreceptors (R5–8) of all ommatidia in both sexes are strongly tuned by the perirhabdomal pigments...
