optic chiasma การใช้

The specific area of the visual pathway at which compression by these tumours occurs is at the optic chiasma.
Fabrica, published in 1543, showing the base of the human brain, including optic chiasma, cerebellum, olfactory bulbs, etc.
After the optic chiasma the visual tracts are referred to as the optic tracts, which enter the thalamus to synapse at the lateral geniculate nucleus ( LGN ).
The axons from the nasal half cross the brain at the optic chiasma to join with axons from the temporal half of the other eye before passing into the lateral geniculate body.
Visual information is then sent to the brain from retinal ganglion cells via the optic nerve to the optic chiasma : a point where the two optic nerves meet and information from the temporal ( contralateral ) visual field crosses to the other side of the brain.
