The optic chiasma is in front of the pituitary gland where optic nerve fibers pass to the brain. The function of the optic chiasma is to relay electric signals as they pass from the optic nerve to the brain.

∙ 14y agoThe optic nerves send electrical signals from each eye to meet in the brain at the optic chiasma. Here, the left visual signal from one eye is combined with the other eye and the same goes for the right visual signal. Now the signals split again. The right visual heads for the left brain and the left visual makes its way to the right side of the brain. This way, visual messages from both eyes will reach both halves of the visual cortex. The brain then merges the image into one image which you are looking out at the world with. This partial crossing of the nerve fibers at the optic chiasm (or chiasma) is the reason why we humans have stereoscopic sight and a sense of depth perception.

What happens at the optic chiasm?
Axons from each retina cross at the optic chiasm.
The optic nerves from the eyes cross before entering the brain the crossed structure is known as?
optic chiasm?
What you see is carried to the occipital lobe by the?
optic nerve (at the back of the eye) which then crosses at the optic chiasm. From this point, the optic tracts travel to the lateral geniculate nucleus, and then on to the visual cortex in the occipital lobe.
Can pituitary gland tumor cause blindness?
Yes, if it presses on the optic chiasm, it can cause blindness. There is effective medical treatment to prevent or address this late complication.
How is the light optic tract anatomically different from the right optic nerve?
The right optic tract carries information from the left hand side of both eyes visual field, where-as the right optic nerve carries information solely from the right had eye. After the optic nerves from both eyes perform this partial intersection (in the optic chiasm) they then become known as the optic tract. Hope this helps.
Where is the optic chiasm?
The optic Chiasm is located where the optic nerves partially cross on the brain
What happens at the optic chiasm?
Axons from each retina cross at the optic chiasm.
Where do the two optic nerves reach the diencephalon?
The Optic Chiasm
What is the point called at which the optic nerves cross?
The optic chiasm
What is the white matter tracts between the optic nerves and optic tracts?
Optic Chiasm
What is the optic intersection in the brain?
The optic chiasm is where the two optic nerves cross in the brain.
Can you see the optic chiasma with an opthalmoscope?
No. The optic chiasm is located at the base of the brain.
Is Optic chiasm the blind spot of eye?
No. The blind spot in the eye is the optic disc, the point where the optic nerve meets the retina. At this point, there are no photoreceptors, so no detection of vision. The optic chiasm is the place near the brain where the optic nerves cross over.
The crossing over of the optic nerves is the?
Optic chiasm is located around the pituitary gland.
What is the anterior visual pathway?
The anterior visual pathway refers to the pathway that visual information takes from the eyes to the visual cortex in the brain. It includes the optic nerves, optic chiasm, optic tracts, and lateral geniculate nucleus. This pathway is responsible for transmitting visual signals from the retina to the brain for processing and interpretation.
What cant be seen as one looks into the eye with an ophthalmoscope?
Optic Chiasm - a crossing point of the optic nerves.
The optic nerves from the eyes cross before entering the brain the crossed structure is known as?
optic chiasm?
