Resuming from where we left off last time, we continue our journey through the visual system by explaining the structure and function of the bipolar and ganglion cells in the retina, including their somewhat complex receptive fields. I then discuss the optic nerve and cross over of information from different visual hemifields at the optic chiasm. We end this part of our journey with a look at the lateral geniculate nucleus, and how it is structurally organised to process different types of visual information in different locations.
