Horizontal cells (HCs) mediate negative feedback to photoreceptors. In the mammalian retina, there are two types of HCs, which are extensively coupled to neighboring cells through homologous gap ...

Vertebrate vision relies on two types of photoreceptors, rods and cones, which signal increments in light intensity with graded hyperpolarizations. Rods operate in the lower range of light intensities ...

Horizontal cells in the retinas of cats and rabbits are morphologically similar; in both species, two types can be distinguished in Golgistained material. Horizontal cells and their processes are ...

Scientists are developing a clearer picture of how visual systems develop in mammals. The findings offer important clues to the origin of retinal disorders later in life. Scientists are developing a ...

Nearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers have discovered in fish ...

Cross-section through part of a retinal organoid: On day 143 of their differentiation, the inner nuclear layer (bottom) contains the cell bodies of functionally distinct cells: those of the amacrine ...

June 28 (UPI) --A team of scientists has developed a new model of the retina that can predict with high precision the outcome of a defined perturbation, which serves as an important step toward a ...

For individuals with inherited eye disorders such as retinitis pigmentosa or macular degeneration, the irreversible degeneration of the retina—a layer of photoreceptors at the back of the eye—can ...

In a genetic association study, investigators integrated data from genome-wide association studies of various disorders with retinal transcriptomic data. Findings revealed that the polygenic risk of ...

BUFFALO, N.Y. – Scientists are developing a clearer picture of how visual systems develop in mammals. The findings offer important clues to the origin of retinal disorders later in life. In research ...
