Presynaptic membrane capacitance measurements indicate coordinated exocytosis but argue for a lesser degree of coordination than suggested by postsynaptic recordings.

Intracellular recordings identified four photoreceptor classes with peak sensitivities in the ultraviolet, blue, green and orange wavelength regions (at 360, 465, 550, 580 nm, respectively) and two morphological ommatidial types were identified.
Photoreceptor responses of fruitflies with normal and reduced arrestin content studied by simultaneous measurements of visual pigment fluorescence and ERG

A steady-state stochastic model was developed to interpret the dependence of the PDA on effective light intensity and arrestin content and to help deduce the arrestin to rhodopsin ratio from the sensitivity and PDA data.
Rhabdom constriction enhances filtering by the red screening pigment in the eye of the Eastern Pale Clouded yellow butterfly, Colias erate (Pieridae)

The remarkable anatomy of the eye of the Eastern Pale Clouded yellow butterfly, Colias erate, is reported, showing the presence of a violet-absorbing pigment that acts as a short-wavelength filter for the proximal photoreceptors.

An imaging scatterometer is described allowing hemispherical reflectance measurements as a function of the angle of incidence, and the instrument's performance is illustrated by measurements of the scattering profiles of the blue-iridescent dorsal wing scales of the nymphalid Morpho aega and the matte-green ventral wing scale of the lycaenid Callophrys rubi.
Photoreceptor spectral tuning by colorful, multilayered facet lenses in long-legged fly eyes (Dolichopodidae)

It is conjecture that the green and orange facets narrow the spectral bandwidths of blue and green central photoreceptors, respectively, thus possibly improving color and/or polarization vision in the dolichopodid Dolichopus nitidus.
Horsefly object-directed polarotaxis is mediated by a stochastically distributed ommatidial subtype in the ventral retina

- BiologyProceedings of the National Academy of Sciences
- 7 October 2019
It is reported that horsefly retina contains 2 ommatidial subtypes that separately analyze polarization of light and color, and how stochastically distributed sensory units with modality-specific division of labor serve as separate and opposing input channels for visual guidance is revealed.

A wavelength combiner based on a reflective planar diffraction grating and light emitting diodes with emission peaks from 350 to 630 nm that were positioned at the angles corresponding to the first diffraction order of the reversed beam that is intrinsically capable of multi-band output.
Spatial reflection patterns of iridescent wings of male pierid butterflies: curved scales reflect at a wider angle than flat scales

Study of the iridescence in the males of a few members of Coliadinae, Gonepteryx aspasia, cleopatra, G. rhamni, and Colias croceus shows that the pigmentary colouration is diffuse whereas the structural colouration creates a directional, line-shaped far-field radiation pattern.
