parietal eye

Of all living tetrapods, the parietal eye is most obvious in this animal.

The parietal eye is part of the pineal system.

The tuatara has a third eye on the top of its head called the parietal eye.

This eye is known as the parietal eye, which looks just like a pale scale on the top of their head.

The parietal eye, as it is called, is only visible in hatchlings.

The parietal eye is only visible in hatchlings, which have a translucent patch at the top centre of the skull.

He thus named himself after the tuatara, a lizard with a parietal eye or "third eye".

The skull had prominent otic notches behind each eye and a parietal eye.

Like many lizards, water dragons have a parietal eye, a light-sensitive "third eye" in the top of the head.

Massive skull roof, with openings only for the nostrils, eyes and a parietal eye, similar to the structure of the anapsids.

Like other iguanids, Cuban iguanas have a white photosensory organ on the top of their heads, called the parietal eye.

Sauroctonus's flattened, triangular skull was about 25 centimeters long, with a parietal eye, a primitive character, on the crown.

A parietal eye, also known as a third eye or pineal eye, is a part of the epithalamus present in some animal species.

The lizard-like reptile tuatara has a "well-developed parietal eye, with small lens and retina".

Unlike other early archosauromorphs, they do not have parietal foramina, which in many reptiles holds a parietal eye.

The parietal eye on top of the head assisted the animal with orientation, rather than its vision, and its presence is regarded as a primitive characteristic.

The parietal eye fields, farther back in the brain, are involved mainly in reflexive saccades, made in response to changes in the view.

"In animals that have lost the parietal eye, including mammals, the pineal sac is retained and condensed into the form of the pineal gland."

The parietal eye uses a different biochemical method of detecting light than rod cells or cone cells in a normal vertebrate eye.

The brain of the Russian Melovatka bird, about 90 million years old, is an exception, and it shows a larger-than-expected parietal eye and pineal gland.

OMA can also be associated with bilateral hemorrhages in the parietal eye fields (PEF).

The roof itself formed a continuous cover over the whole of the head, leaving only openings for nostrils, eyes and a parietal eye between the parietal bones.

The parietal eye fields begin reflexive saccades on the abrupt appearance of visual targets, allowing reflexive exploration of the visual scene.

The triggering of saccades is done by three separate cortical areas, the frontal eye fields, the parietal eye fields and the supplementary eye fields.

The function of the parietal eye is unknown, but it may be useful in absorbing ultraviolet rays to manufacture vitamin D. It may also do other things.
