photoreceptor cell

The eyes are simple in structure, sometimes with just a single photoreceptor cell.

Thus defined, they need not consist of more than one photoreceptor cell.

Without proper function of the photoreceptor cells, vision is not possible.

The exact mechanism of photoreceptor cell death is not clearly understood.

The retina, at the back of the eye, contains photoreceptor cells.

This explains why colors cannot be seen at low light levels: only one type of photoreceptor cell is active.

Once photoreceptor cells die, however, they cannot be restored.

The photoreceptor cells involved in vision are the rods and cones.

The simplest photoreceptor cells in conscious vision connect light to movement.

They help integrate and regulate the input from multiple photoreceptor cells.

Eventually, the photoreceptor cells die, leaving the animals blind.

It has been suggested that pinealocytes are derived from photoreceptor cells.

Visual system consists of the photoreceptor cells, optic nerve, and V1.

Therefore the tips must contain the photoreceptor cells although the bending takes place lower down on the shoot.

A transient increase of only 10 C can destroy retinal photoreceptor cells.

A common theory on the evolution of pinealocytes is that they evolved from photoreceptor cells.

In advanced stages of the disease, photoreceptor cells may be irreversibly damaged.

The only neurons that are directly sensitive to light are the photoreceptor cells.

This disorder is characterized by the progressive loss of photoreceptor cells and may eventually lead to blindness.

Photoreceptor cell death is the eventual outcome of retinal degeneration.

Photoreceptor cells are around 3 m in diameter.

The Hartline-Ratliff model describes interactions within a group of p photoreceptor cells.

A light photon interacts with the retinal in a photoreceptor cell.

Behind each lens lies a single cluster of photoreceptor cells, termed a retinula.

Oil droplets are found in the eyes of some animals, being located in the photoreceptor cells.
