they demonstrated that eye movements are finely tuned to provide optimal sampling by the cones. Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific ...

Each eye is about the same volume as the animal's brain ... where many individual lenses focus light onto groups of photoreceptor cells. This group of hard-shelled prehistoric creatures had crystal ...

Each eye has a unique density pattern in their ... of the visual stimuli on the retina to later determine which photoreceptor cells contributed to vision in each participant.

As blood leaks into the eye, it can cause a separation of the light-sensing photoreceptor cells from the retinal membrane. This separation prevents cells from receiving much-needed nutrients ...

The study found that small, controlled eye movements (fixational drift) helped participants see details smaller than a single photoreceptor cell (the tiny light-sensitive cells in the eye). The ...

This particularly affects the eye's photoreceptor cells, causing retinitis pigmentosa. The retina slowly degenerates, leading to blindness. The fact that defects in eleven different Usher genes ...

Here, we used deep full-length single-cell RNA-sequencing to distinguish post-mitotic cone and rod developmental states and cone-specific features that contribute to retinoblastomagenesis. The ...

Some cases result in the patient making a photoreceptor protein ... that sits in the back of the eye is considered a retinal ...

The Saint Louis University Department of Ophthalmology is a major tertiary eye care center, staffed by members of ... in the context of retinal degenerations Molecular mechanisms of photoreceptor ...

iPS cells are being used to treat eye diseases to address donor shortages. We explore advancements made in Japan, such as the transplantation of iPS cell-derived corneal cells and retinal sheets.
