This chapter focuses on the anatomical location of photoreceptors and clocks. Although individual cells—in protists and metazoa—probably contain or constitute clocks in their own right, it is probable that particular groups of cells or organs in the metazoan organism have a particular clock ...
Distribution of photoperiodic receptors in the compound eyes of the bean bug, Riptortus clavatus The bean bug, Riptortus clavatus shows a long-day photoperiodic response with respect to the control of adult diapause. The location of photoreceptors for... A Morita,H Numata - 《Journal of Comparat...
However, without receptors, the body wouldn't have these special powers. Receptors are usually protein structures within or near each of the sensory organ cells that allow the organ to detect various changes to complete the sensory process. For example, photoreceptors detect changes in light, ...
Advanced photodetectors with intelligent functions are expected to take an important role in future technology. However, completing complex detection tasks within a limited number of pixels is still challenging. Here, we report a differential perovskite
Miniature eye movements refresh photoreceptors, preventing images from disappearing, as occurs when those images are stabilized on the retina. Miniature eye movements also cause the autokinetic illusion, the tendency to see a single, stationary point of light wander about jerkily in a dark surround. ...
241 provide methods for inducing desired biological responses in an organism by emitting a photon signal from one or more LED lights with two or more components that are designed to induce a biological response by stimulating photoreceptors of an organism and/or then resetting the photoreceptor to ...
the one hand, faces the ends of the fibers to the corresponding photodetectors of the array of photoreceptors, and on the other hand, the ends of the fibers of the tow are facing the output of the optical objective of the photodetector device and are located in its focal plane, the ...
We recorded intracellular membrane potential responses from a superfused, sliced preparation of the locust ( Locusta migratoria) eye which allowed localized stimulation of the photoreceptors. The average amplitude of bumps was affected very weakly by stimulus location, in a way which could be accounted...
However, zebrafish react most strongly and consistently to lateral, nearly equatorial stimuli, consistent with previously reported higher spatial densities in the central retina of red, green and blue photoreceptors. Upside-down experiments suggest further extra-retinal processing. Our results demonstrate ...
Choroidal metastasis showed a minimally "lumpy, bumpy" surface topography and with overlying subretinal fluid and shaggy photoreceptors. Choroidal hemangioma showed a smooth, dome-shaped topography, with expansion of the affected small, medium, and large choroidal vessels. Choroidal lymphoma showed varying...
