Lecture 3: Visual perception

Have you ever wondered how our brain processes information when we see objects from the outside world?

Many cognitive neuroscientists focus on visual perception, which would be the most important perception to people.

What are they?

• The dorsal pathway of visual perception helps us to identify where an object is and the relative position between the object and other things.
• The ventral pathway helps us to identify what an object is and its semantic relationship with others.
