About the lecture

In the first mini-lecture, we introduce the sensory organ that allows us to see, the eye. The eye is introduced as part of the brain, as the connectivity between the two is quickly apparent as we appreciate the amount of the brain that is devoted to processing visual information. To begin, we discuss the journey that incoming light takes coming into the eye, allowing us to see visual stimuli. We discuss the importance of the lens, the cornea, the iris, and the retina. To finish off, we demonstrate using a binocular eye tracker to illustrate how the brain combines light intensity information from both eyes to determine how constricted both pupils should be.
