- Synopsis
- This image shows the pathway of the optic nerves from the eyes to the brain. There is a locator dot shown, which will be at the top left of the page when the image is the right way up. It is shown as a top-down (plan) view of a horizontal cross section through the eyes and brain (eyes on the left hand side, and back of head on the right hand side). It reads from left to right. The diagram is split into 5 vertical sections labelled above, and each section is separated by vertical dotted lines. The first section on the left is labelled Eyes, and below this are two circles representing eyes, with the left eye below the right eye. The sections after this are all within the brain. The second section Optic nerve shows a solid line extending from the left of each eye and a dashed line extending from the right of each eye. These are the optic nerves and labels next to the lines explain which side of the eye each optic nerve extends from. The next section Optic chiasm shows two of the optic nerves crossing. The left optic nerve from the right eye crosses the right optic nerve from the left eye. The next section Lateral geniculate bodies shows two circles. The lower one is on the left side of the brain, and the upper one is on the right side of the brain. The two solid lines from each eye meet at the lower circle and the two dashed lines meet at the upper circle. The final section Visual cortex shows the back of the brain, with the two hemispheres left and right. The dashed line from the right Lateral geniculate body goes to the right hemisphere and the solid line from the left Lateral geniculate body goes to the left hemisphere. This means that the right side of each eye is represented in the right hand side of the brain and the left side of each eye is represented in the left side of the brain.
