the anatomical point behind the eyes in front of the pituitary gland where the left and right branches of the optic nerves join to form a cross-shaped structure Within the optic chiasm, some of the nerve fibers cross.
The site on the base of the brain where roughly half the nerve fibers from each eye cross to the opposite side of the brain and half stay on the same side. (From the Greek letter chi, X, whose shape is a cross.)
The point of decussation (crossing) of optic nerves.
A (Gr. crossed as in the letter X): Landmark for the rostral-most border of the hypothalamus on the ventral surface of the brain. It is the point of convergence of the optic nerves and where optic nerve fibers from the nasal halves of each retina cross the midline on their way to the contralateral thalamus and visual cortex.
the point under the frontal lobes at which some axons from each of the optic nerves cross over to the opposite side of the brain. (159)
The area in the optic tract where information from each eye crisscrosses. Fibers from each eye cross over to the opposite side, while other fibers remain on their respective side. It is in this way that information from each eye is received and processed on both sides of the brain.
The area where the 2 optic nerves cross.
Crossing of the fibers from each retina.
The cross over point of the optic nerve, where ganglion cell axons from the temporal and nasal portions of the retina are sorted to ipsilateral or contralateral projections to the lateral geniculate nucleus.
Part of the pathways that carry the visual information from the retina in the eyes to the lateral geniculat nucleus. In particular at this location, the axons carrying information from the nasal half of each retina cross, that is decussate, which the axons from the temporal retina do not decussate.
controls vision and the optic nerve. It is the area in the front of the brain where the optic nerves cross one another.
The optic chiasm (Greek χίασμα, "crossing", from the Greek χλαζειν 'to mark with an X', after the Greek letter 'Χ', chi) is the part of the brain where the optic nerves partially cross.
