All our senses are just action potentials that are passed along the neurons of our various sensory pathways. Arguably, the most relevant sense to the human condition is the sense of sight. We may believe that we see things in the real world, but do we?
In this week’s case study explain the process of how our sensory nerves turn the energy of light waves into nerve impulses that our brains can read. Then discuss how the visual field allows humans to navigate between locations through the construction of a spatial map.
