Sentences with phrase «types of photoreceptor cells»

The eyes contain two different types of photoreceptor cells that affect the way everyone sees things, and this is true of both dogs and people.

It took nearly eight decades for scientists to investigate his claim and prove him right: The eye really does contain a third type of photoreceptor cells that sense light intensity without detecting images.

Not exact matches

The downside is that people with these eye diseases are losing sight in large part because they're losing a different type of eye cell: the photoreceptors that sense light in the retina.

After initiating photoreceptor loss in the fish retinas, the researchers monitored the immune system's response by tracking the activity of three types of fluorescently labeled immune cells in and around the eye: neutrophils, microglia and peripheral macrophages.

They were able to follow the activity of the immune cells using time - lapse 3 - D microscopy imaging of fish retinas and found that neutrophils, the type of immune cells that are typically the first responders to tissue injury, were largely unresponsive to photoreceptor death.

The second layer is made of bipolar cells that act as a conduit between the photoreceptor and the third type of cell, the ganglion, which transmits the light signals to the brain.

Functional damage to these photoreceptors, or pathological loss of the cells that bear them, results in inability to register light impinging on the retina — and is responsible for various types of visual impairment and certain forms of congenital blindness.

The researchers injured the mice retinas with a toxin that causes cell death in retinal ganglion cells and interneurons, another type of retinal cell whose job it is to transmit signals from photoreceptors to the brain.

In wild - type, retinal ganglion cell layer (GCL), inner nuclear layer (INL), inner plexiform layer (IPL), and nuclear layers of rod and cone photoreceptors are distinct, and rod outer segment (OS) is observed at the outer-most layer of the retina.

These cells can develop into any type of retinal cell, including RPE cells or photoreceptors.

These retinal cells are the type that are killed off in macular degeneration, eventually leading to the death of photoreceptors, and the gradual loss of central vision.
