THE VISUAL PATHWAY
We will organize our description of the visual system into six parts, which correspond to six regions of the visual pathway.
1) The region anterior to the optic chiasm.
2) The optic chiasm.
3) The region between the optic chiasm and the lateral geniculate nucleus - in other words, the region where the optic tract conveys information centrally.
4) The level of the thalamic relay for visual information - through the lateral geniculate nucleus.
5) The pathway by which visual information traverses the internal capsule to reach the visual cortex - termed the visual radiation.
6) The visual cortex.
