Fantastic animations about the eye, visual processing in the retina and the pathways that visual information travels in the brain.
Pay close attention to the "center-surround" aspects of retinal processing it this first video.
 |
| This animation shows how the photoreceptors, bipolar and ganglion cells of the retina are organized in "center-surround" arrangements that allow "bottom up" processing of visual information to begin in the retina. |
If a picture is worth a thousand words, an animation is worth way more. This animation really shows the visual pathway very well. Pay attention to how visual information is split in the Optic Chiasm and how it routs through the LGN of the thalamus as well as other areas specifically related to eye movement and the "biological clock" which controls circadian rhythms.
 |
| This excellent animation really explains how the visual information from the left and right visual fields makes its way to the right and left occipital lobes via the LGN of the thalamus. |
Check out this amazingly comprehensive video that covers the visual system in about 10 minutes. It's on YouTube, so it may be hard to watch at school. Link: http://youtu.be/AuLR0kzfwBU
