Visual Processing and the Visual Cortex

The video tutorial explores how sensory information is processed, focusing on vision. It covers the basics of how light interacts with the eyes, the structure of the retina, and the roles of rods and cones. The process of visual transduction is explained, detailing how light is converted into neural signals. The tutorial also discusses the pathways these signals take to reach the brain's visual cortex and how different brain regions interpret visual information.

Which sense is primarily responsible for perceiving objects around us?
