Changes in electrophysiological properties of photoreceptors in Periplaneta americana associated with the loss of screening pigment. J Comp Physiol A Neuroethol Sens Neural Behav Physiol. 2018;204:915-928 pubmed publisher
    ..Overall, these differences can be related to the loss of screening pigment function and to a compensatory decrease in the rhabdomere size in W-E retinae. ..

    ..3 bits s(-1), much higher than in G. lacustris but smaller than in N. glauca. These findings support the hypothesis that Corixa's retinal function is adapted to its diurnal life-style, which is also consistent with field observations. ..

    ..On the other hand, the Ca(2+) channel results are consistent with previous observations indicating that, in contrast to K(+) channels, strength of celecoxib effects on LTCCs strongly varies from species to species. ..

    ..We conclude that TRPL channels provide high-gain/high-noise transduction, suitable for vision in dim light, whereas transduction by TRP channels is relatively low-gain/low-noise and allows better information transfer in bright light. ..

    ..These findings raise the issue of whether the evolutionary tuning of photoreceptor properties to visual demands proceeded differently in Blattodea than in Diptera. ..
