The optic nerve connects the brain to the eye. To biologists, the optic chiasm is thought to be a turning point in evolution.   It is thought that the crossing and uncrossing optic nerve ...

The optic nerve is the nerve that transmits visual information from the retina to the brain. The optic nerve is composed of retinal ganglion cell axons and support cells. It leaves the orbit (eye ...

The optic nerves transmit visual signals from the eye to the brain. Optic nerve glioma is rare, accounting for only 5% of all childhood brain tumors. They are most common in children under the age ...

The optic chiasm is the place within the brain where some of the nerves from each eye cross. An MRI can also show any other brain abnormalities that may be present.

As the tumor grows, it may compress the optic chiasm, a critical structure directly above the pituitary gland. This is where the optic nerves from each eye cross and then project to the brain.

The optic chiasm senses light and controls daily body rhythms. It is the first place in the brain the optic nerve touches. It took the severed nerve cells about six weeks to regrow to the optic ...

"This indicates that the M1 treatment sustains long-distance axon regeneration from the optic chiasm, i.e. midway between the eyes and target brain region, to multiple subcortical visual targets ...

Traumatic injury to the brain, spinal cord and optic nerve in the central nervous system (CNS) are the leading cause of disability and the second leading cause of death worldwide.

Researchers describe a previously unknown component of brain anatomy that acts as both a protective barrier and platform from which immune cells surveil the brain for infection and inflammation.
