Our next insight into biological visual systems comes from a series of experiments conducted by scientists from Harvard University, back in the late 1950s. Nobel laureates David Hubel and Torstein Wiesel showed the world the inner workings of the mammalian visual cortex, by mapping the action of receptor cells along with the visual pathway of a cat, from the retina to the visual cortex. These scientists used electrophysiology to understand exactly how our sensory organs intake, process, and interpret electromagnetic radiation, to generate the reality we see around us. This allowed them to better appreciate the flow of stimuli and related responses that occur at the level of individual neurons:
The following screenshot describes how cells respond to light:
Thanks to their experiments in the field of neuroscience, we are able to share with you several...
